U350 strange sound/video problem

Hi All,
 two days ago I bought U350 model and unfortunately I already have problems... Today I played a video and I noticed that sometimes it stops the video and audio for a couple of seconds and then continue. More rarely the sound just stops and returns only if I re-open the file. I also noticed that the computer very often loses sound when I am moving it( gently pushing that bottom right part - near the battery - around 80% of the cases).
Today my winamp crashed and made some horrible sound. No Ctrl-Alt-Del worked. I had to kill it by the Power button. I guess that this is hardware problem but I am not sure that I can reproduce it correctly in a service Can anyone help me explain what's the problem/solution so I can get it fixed? It has 2 year warranty..
Regards,
Tsveti

Hi,
I made a clear windows installation and updated the video/audio drivers.
The results pretty much surprised me. I tried to play one at the same movie with 4 players -  Windows media player, Windows player classic, VLC and KMPlayer.
I observed the same false bahaviour with all but Windows player CLASSIC. Only with this player everything's fine! The other three have same problem - when moving laptop(sometimes without even moving it) audio/video intermits(or sound stops functioning until re-open file).
I really don't have explaination for that...it turns out that problem may be partly software...Is it possible that Windows classic proccess files in some different way?
Later I will try to make Skype work too...
In this case maybe problem can be solved with new driver...
Thanks for the patience. If I make skype and youtube work fine(somehow) I won't need to go to service...

  • IMac 600 SE - strange power/video problems - need motherboard?

    Hello all,
    Got this "project" iMac, have no knowledge of its history. Here's what's going on:
    When I first got it, it would take 3 or 4 tries for it to fully boot up, on the first try it would shut off after a second or two, the next try it would get a little further along before shutting down and finally on the 3rd or 4th try, it would boot up completely.
    Initially, it had a dim display and a bunch of wavy horizontal lines, like a TV with bad reception using a "rabbit ears" antenna. The person I got it from said from what he had learned, he thought it was a power supply problem.
    So I replaced the down converter/power supply with a spare one I had leftover from a previous motherboard replacement, which made no difference at all, same problems.
    So I then checked the firmware, which was the latest version (4.1.9). Then I did a PRAM reset, which helped, followed by a PMU reset. I did the PRAM reset several times when problems cropped again, and have done the PMU reset twice, resetting the clock both times.
    The shutdowns on boot up have disappeared, but it will occasionally shut down out of the blue after being on for awhile now. The horizontal lines have disappeared, but it now has a strange video problem:
    The geometry of the screen is off-kilter by default, so when I go into System Properties to reset the geometry there, and I use the "Rotate" command to correct the overall incline in the display from right to left, the display gets dimmer, and sometimes the horizontal lines reappear, usually on the right side of the screen. When I click on "Factory Defaults", the display gradually brightens again, and if horizontal lines are present, they disappear. This phenomenon doesn't appear to occur when I adjust the display height and position, only with the "Rotate" command, rotating it counter-clockwise. I believe the iMac even shut down once when I was doing this.
    I have also noticed an occasional higher-pitched "whine" on boot up, which usually results in an eventual shut down.
    So, are these problems symptomatic of a bad motherboard or a bad video board/card? Since I have the latest firmware and have tried both PRAM and PMU resets, and the occasional random shut down still occurs, it makes me think it's a hardware problem.
    I just need some feedback here before I purchase a replacement motherboard.
    Also, can the video board/card be replaced separately?
    Thanks for any ideas/suggestions/help!

    In your situation I believe 2 components need checked first. PAV board and the CRT. Or essentially anything shared by the 2 items, such as the CRT yoke/gun board.
    As far as the logic board goes, the video chip-set is part of it (soldered in) and not repairable. Those parts rarely "weaken" (normally just die) so I would be less likely to suspect them.

  • Flash Player Sound & Video Problem

    Since I have downloaded flash player 11 my videos in explorer are not right. The video and sound are out of sync. Have searched the forums and found no fixes. Can you help? Thanks

    To help troubleshoot we'll need the following system information:
    Operating   system  
    Browser  
    Flash   Player version
    When reporting issues with video or audio, it's also helpful to get your system hardware and driver details.  Instructions for finding this information can be found here:
    Windows  
    Mac
    Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player.  I recommend trying both of the links below to see how they perform.  If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing.  You can verify the use of HTML5 by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the context menu.

    I bought this board to run a HTPC system and seem to be having problems with slow running and video playback.
    Apart from windows / drivers and PowerDVD nothing else is running on this machine, no firewall, virus checking etc.
    The first thing I noticed was how long it took to load windows, defrag the hard drive and load other applications, compared to my old Celeron 2.4 / MSI 865pe machine.
    Video play back using PowerDVD from the hard drive or DVD player is extremely stuttery, the sound is awful ( speech sounded like people were under water ).
    I disabled the on board sound and installed an old sound blaster card which improved the sound quality.
    Do I need to purchase a separate video and sound card to be able to watch DVDs or should the on board sound and video be enough.
    Thanks for the help   

    OK....that's consistent with prior reports of slow SATA performance with Win2K and SATA using that combination.  If you check Device Manager for the "IDE Channel" for the drive, it should also report operating in PIO Mode, i.e. it's not running DMA.  That would confirm the problem.
    I'm not sure yet what is a good solution.  The combination works in XP (IDE mode and XP IDE driver), but not Win2K, so I'm guessing DRIVER.  I did suggest trying install of the SATA driver and/or switching Bios mode to RAID and trying the SATA driver during Setup at F6 prompt to others, but don't recall seeing any posts suggesting those recommendations worked.
    In my opinion, that's the first item to work-on/fix.  I'm also aware that the latest ATI IGP driver 5.6 set is reported buggy and the Realtek drivers on the latest MSI CD are buggy.  Drivers on the orignal CD worked OK.  I did post a link for the original Realtek drivers for download on another Forum thread.

  • Sound/Video Problem after Downloading iTunes 10.5

    I recently downloaded the most recent iTunes update, 10.5. After downloading it, I am having problems with the sound and picture of television shows. When I try to watch a tv show, the sound is muffled, and the picture slows or skips constantly. This happens on every tv show I've tried to play, not just one. I haven't noticed any problems with sound from songs though. I had this problem once before after downloading the previous version of iTunes, and completely uninstalled and reinstalled iTunes to solve the issue, and it worked. However, I tried doing it once again this time, and there was no success. I've tried disabling sound enhancements, and that also had no effect. Quicktime is installed and updated as well. I'm running Windows 7. Any help or advice is appeciated.

    I'm not sure I quite understand what you mean. iTunes doesn't save a folder of playlists, but if you mean that the iTunes library is empty, or doesn't contain playlists that it had before the upgrade then either restore your backup or make use of the following...
    Empty/corrupt library after upgrade/crash
    Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps youshouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
    See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
    When you get it all working make a backup!

  • Strange sound/sync problem after encoding in CS4

    Hi guys and gals, wonder if anyone can help me out on this one?
    I'm running PPro CS4 on a purpose-built matrox rtx2 system, working mostly from DVCAM.
    I've done a complete edit, cutting various interview soundbites over  music to make a testimonial montage. After doing the complete audio mix,  everything sounds fine and dandy when I preview it after rendering. The  problem occurs when I output the film using AME to a variety of  different formats. Where previously I had precise edits on the timeline,  the audio cuts sound to be a couple of frames out. For example, one cut  occurs just after the line 'ideal product for our needs' and sounds  exactly as it should on the timeline, but on the outputted file it  sounds like he says 'ideal product for our nee...'
    Same thing occasionally happens on music mixes, when I cut to the beat  to use different sections of the backing track and crossfade through, it  sounds fine on the timeline but then after I output the file then cuts  the sound off the beat and the music sounds like it goes slightly out of  time on the transition.
    I've even tried rendering it out as a wav file, but that doesn't work either.
    Is it something I'm doing wrong? I've checked and it's all 48k sound  (and if it was a sample rate issue I assume it would appear on the  timeline as well). Or is it another to add to the long list of problems  we've had with the matrox setup?
    Any help will be greatly appreciated!
    Cheers,
    Kev

    Kev,
    Could it be that the preview of the timeline is inaccurate as opposed to the outputted file?
    Let's check this out. First, is there a red line above your Clips in the Timeline, just below the Timeline Ruler? If so, hit Enter to Render those Clips for smoothest playback. Note: Audio can need Rendering too. Does this help?
    If not, set the WAB (Work Area Bar) over a small section of the Timeline, though one that exhibits the OOS issue. Export to your desired format/CODEC and test. Do you get OOS in the Export?
    For a bit more on Rendering, see this ARTICLE.
    For a look at the WAB, see below:
    Good luck, and please report,

  • Hi! I´m having problems with showing video files in Qlab on my Macbook Air. A sound/video technician told me to "blow out" my Mac. Was told to use  cmd+ r  when restarting. Is this the right way?

    Hi! I´m having problems with showing video files in Qlab on my Macbook Air. It started suddenly. Consulted a sound/video technician who told me to "blow out" my Mac. Was told to use cmd+r  when restarting. Is this the right way to clean up my Mac? And is it likely that some kind of bug is causing problems for Qlab to show video files? I´ve already tried with a bunch of different video files and sometimes Qlab plays them and sometimes not. I need the Qlab playlist for a theatre show and only have a week until showtime so starting to really worry. Is there anyone out there who can help?

    It also takes time for the photos to be transferred out of your iPhone and into Photo stream on Apple's iCloud servers.
    Note that this can't happen if your iPhone is not connected to a WiFi network:
    When you enable My Photo Stream on your devices, all new photos you take or import to those devices will be automatically added to your photo stream.
    iOS devices: New photos you take are automatically uploaded to your photo stream when you leave the Camera app and are connected to Wi-Fi. My Photo Stream does not push photos over cellular connections.
    Macs: Any new photos you import to iPhoto or Aperture begin uploading automatically when you have a Wi-Fi or Ethernet connection. Or you can change your iPhoto or Aperture preferences so that only photos you manually add to My Photo Stream are uploaded.
    PC with iCloud Control Panel 2.0 or later: Open a Windows Explorer window and under Favorites select iCloud Photos if you are using iCloud Control Panel 3.0 (or Photo Stream if you are using 2.0 to 2.1.2). Open My Photo Stream. Click the "Add photos" button. Select the photos to import to My Photo Stream, then click Open.

  • My hard drive is doing a strange sound all the time for a week now, it's not like a clicking noise, it's something else, anyone has this problem too?

    Hi guys, my macbook pro is doing a strange sound, not a clicking noise like other users could have, I don't have any apple center closer than 2hours drive so if somebody had this problem too and solved it it would be great!

  • Problem 1/2 with lenovo T400s = strange sound

    Hello,
    my new lenovo T400s works quite fine. But two things are getting on my nerves!
    The first problem is a very strange sound. It's not very loud but its a very aggravating sound! In some forum posts people explained the reason of the strange noise is caused by the switching between the c2 and c4 processor state. So I tried the kernel option
    processor.max_cstate=2
    But the sound is still there.
    I would be very very glad if someone could help me. Every hint is very welcome.
    tia and greetings,

  • Strange sound problems with Terminal

    I've been having a strange sound issue for a couple months now that's driving me insane. What seems to happen is that when I launch/close Terminal the sound volume seems to change. It usually increases, but sometimes the output device toggles to the internal speaker. It's very strange, very frustrating, and very reproducible.
    I have reset PRAM, done an SMC reset, cleared every cache I can think of, reset preferences on Terminal, checked bash-related (profile, bashrc, etc) and nothing seems to help. It does appear that it's iTunes specific - the volume of DVD player doesn't change when I use terminal in a similar way. If I remember correctly, I had the problem before my Leopard upgrade as well. I have the MS intellitype/intellipoint utilities installed for my keyboard/mouse, although I don't know if that matters.
    Any idea what could be causing this?
    thanks!

  • Strange sound issue with my Satelite U300

    I've got a strange sound problem with my laptop.
    I have XP pro + SP3 (downgraded from Vista to XP)
    Couple week ago, a reinstall XP, because I thought it could solve my problem. But...nothing.
    This is a problem: When I turning my laptop on, it gives me a message, "warning, cannot access volume control". When I check device manager, the only yellow question mark is bout PCI memory controller and there is no more unrecognized devices founded.
    In Sound, video and game controller - Realtek High definition Audio is just missing.
    Usually , then everything is ok, in "Device manager - Sound, video and game controller " I have - Audio Codecs, Legacy Audio drivers, Legacy Video CApture Devices, Media Control Devices,
    Video codecs, Realtek High definition Audio. But then sound is missing, the "Realtek High definition Audio" is also missing.
    Computers restart doesn't help. Even, when I uninstall Realtek sound drivers from "Add and remove.." and install it freshly, it also doesn't help. I tried to update drivers - nothing..
    But, there is one strange thing: When a turning my laptop on couples hours later, or even next day (for exmpl) everything is ok. Sound works. And I can understand why....
    All drivers downloaded from Toshiba. BIOS is being updated.
    Maybe somebody know how to solve this problem? Any solutions?

    Hello
    This issue has been brought up on this forum several times under other topic headings. Look under Audio Driver Missing, for instance. I have had this exact problem since purchasing my Toshiba notebook more than a year ago. Toshiba tech support is useless - and you're right that BIOS updates or changes make no difference, at least so far. The other ideas or replies given so far on this forum also don't solve the problem. Unfortunately for now I think you have to live with it, until someone spends the time to figure out what is really going on. I am curious if it is a Toshiba problem, a Realtek problem, or a Vista / compatibility issue.
    I have two suggestions, which aren't fixes, but can help get your sound back when it disappears:
    1. Restart several times, not just once. Sometimes it works.
    2. Try the System Restore function. This used to work for me, until I updated the BIOS and now it no longer helps with this issue!
    Make sure you post a solution if you figure it out!

  • T400 - Video problems and a long wait for repair...

    Hi,
    I'd just like to state my experience with Lenovo Customer Support for a video problem with my T400.  Bottom line, as of today, it's been around 27 business days that it's been with Lenovo, and 41 days total since it's failed on me, and nobody, including Lenovo Customer Support, seems to know what its status is exactly, except that they're waiting on a part which has no ETA.
    In July 2009, I bought a T400, a 2764CTO version with the switchable graphics between the internal intel graphics and the ATI GPU.
    All was well until February 1st, 2010, when the LCD sudden wouldn't work.  Well, it would work, but the screen was very very dim, even with the display maxed out on brightness.  You would have literally bring your nose to the screen in order to even make out any text or images - definitely unusable.  However, if you hooked up an external monitor via the video output, the T400 would display video output properly that way.  When I did this, I noticed that the switchable graphics option wasn't there any more - couldn't switch to the ATI GPU.  Based on this, I figured it must be a video card or LCD issue, or a combination of both.
    So, I called Lenovo Customer Support (CS) at 1-800-565-3344, since I'm up here in Canada, and I initially was issued a case number of 41JRFSD, and I agreed to send it to a local Lenovo Repair Centre.  Oops, my bad, I made a mistake using the locator tool I was told to use at bplocator.lenovo.com, and thought the Centre was relatively close.  Not quite.  So, I called Lenovo CS again, and they issued me with a new case number, 40KWSYF, and said they'd send a box for return to depot.  And within 2 days, Feb 2nd or 3rd, I got a Purolator courier return box.  That's fast service!  Pleased, I put my T400 in according to instructions, and I sent it off.
    Fast forward to about mid-February.  I called Lenovo CS, and apparently there was a delay - the depot needed a part that wasn't in stock. Fine, I know these things can happen - I'll wait.
    Fast forward to March 1st.  I talk to a Lenovo CS rep, and it appears that the part needed has arrived, and they've put a rush order to get the computer back to me. Great!
    Fast forward to March 8th, still no computer.  I talk to another Lenovo CS rep... strange, there's no update.  The issue gets escalated to the Depot managers.
    Fast forward to March 12th.  Still no word on my T400's status.  An email fron CS has been sent to the depot.  Not even the CS reps know what's going on.  The rep I talk to figures there should be a response by the end of the day.
    Fast forward to today, March 13th, 4:50pm Pacific Time.  I just finish talking to Lenovo CS, there's been no response from the depot.  Apparently there's a part that they're waiting on for repairs, but there's no ETA on it.  Is it the same part that I've waiting on all this time?  Is it a new one?  I don't know. 
    At this point, I've been told to send an email explaining my situation, and I've also been told to talk to Scott the next time I call CS on Monday after 3pm Eastern.  I have to stress that the Lenovo Customer Support Reps I've talked to have all been very sympathetic and have been courteous, helpful, and professional - something I appreciate from having worked in Customer Support myself.  But the bottom line remains: my computer's not back to me.
    So, my questions to the community here: is my experience here typical?  Is there any hope of my seeing my computer back, or even at least just the hard drive?  I've used Lenovo computers for work for the past 7 years, and it was my good work experiences that led me to buying a Lenovo for home use.  However, it's been a while since I've been without my T400, and I was hoping to get my taxes done on the computer too, since they're due at the end of March.  I'll reserve judgement on Lenovo until I get my computer back, but at this point, all I can say is... I'm disappointed.
    If you're reading this, I'll let you judge my experience for youself.  I'll update my case as it progresses. 
    Thanks!
    Moderator edit: Removed support contact private information, per the Community Rules.

    Hi all,
    So, an update with some good news: my computer is finally back!  
    After a total of over 40 business days (just over 2 months) I finally have my T400 back at home, working again!
    According to the spec sheets, the repair depot had to replace: the systemboard/planar, display/LCD panel, LCD cable, PC card, bluetooth, and the inverter.  BIOS/Embedded controller was also updated, along with the regular diagnostics to ensure everything was working properly.
    I give Lenovo credit though: they got the final parts to repair the computer on Monday, April 5th, and shipped my computer back to me for the next day (today, April 6th).  That's fast service, once repaired!
    However, my case spans over 4 screens of updates and repair depot orders of parts.
    Also, it took me over 10 calls to Lenovo's Customer Service, plus an escalation to a higher-level manager after 1 month had passed, to get progress updates and ETAs for repair.
    Lenovo called me only once to give me an update, and that was the manager whom my issue was escalated to: all the other times, I called Lenovo for an update.
    The story doesn't end here, however:
    In talking to Customer Support, they told me that Sales might be able to sell me an extended warranty at a discount, given the issues I had.  And indeed, after talking to Sales, they offered me a 1 year warranty extension at a price of just over $100 CDN, plus tax.  This is a sale price, compared to the regular retail of $129.  Unfortunately, they can't sell me just one month.
    At this point, I refused their offer, and again escalated to a manager to request an extension of exactly 1 month on my existing warranty.  I figure 1 month delay in repairs, that's plausible - crap happens, and while most repairs take 5-10 business days, I can understand it can sometimes go higher.  Two months though....  My request for a warranty extension is being considered by the manager it was escalated to.
    So, one last question for you folks reading this: am I being unreasonable, talking to Lenovo support one more time to request a 1 month extension of my warranty, given the length of time it's taken for repairs?  I'll post the response Lenovo will give me tomorrow, as they've said they'll do.
    One thing for sure: Lenovo's response will definitely influence my choice of brand from whom to buy a new computer (and it will influence the choice of my friends who've heard my issues, and maybe yours too).  My particular repair problem may not come up often, but if it does happen to you, I'd be happy to know of your experience.
    Thanks for sticking with me through the drama!

  • Why does a Safe Boot fix my video problem?

    After visiting my local Genius Bar twice (and getting two different answers), I erased and reinstalled Snow Leopard 10.6 on my late-2006 "white plastic" iMac.
    I reinstalled the version of SL that came with the iMac, then upgraded it twice to OS 10.6.8. Software Updater says all of my OS components are up-to-date.
    My video-corruption problems ("ghosting", "tearing", pixelation of icon, then the kernel CRASHES within 20 minutes) appear when I boot normally. But they permanently disappear when I reboot into the Safe Mode! 
    I've search Apple.com and every other site I can find without a clear answer to this:
    What extensions, StartUp items, software daemons or gremlins DO NOT load in Safe Mode? Shouldn't one of them be the cause of my problem? Or does Safe Boot work on a hardware-level, too?
    This happens on ALL accounts, both Admin and regular users. No external devices are connected except the wired mouse and wired keyboard.
    I've zapped the PRAM three times, and I've unplugged it for hours. Disk Utility shows everything is good, too. There's about 50 gigs left on the internal 750 GB hard drive.
    The so-called "Geniuses" both ran their Triage OS off an external drive and my iMac hardware passed ALL of their tests. One said it just needed a reinstall (a free fix!!), and the other said my video card is bad ($800, and I have to use an outside repair shop).
    Can someone give me an idea how to proceed? I've been working in Safe Mode for days, but that prevents me from using: Sound, my home network, fonts, Preview, editing in iPhoto, etc.
    Thanks.

    Hi, Mike,
    Thanks for the quick reply.
    I read the linked post about QE, but I don't see how it could help me troubleshoot my problem. Could you clarify: is QE a piece of "software" (that is, a file -- like an extension)?
    If QE IS a piece of software that is disabled in a Safe Boot, I should be able to move it to my Desktop and restart. If my video problem is eliminated, the QE software is the problem, right?
    But then, if my problem is caused by a file/extension, why would the problem occur (and be eliminated in a Safe Boot) right after I re-installed the OS? Shouldn't all the System software be pristine right after re-installation? But since it's NOT fixed by the re-installation, it seems like a hardware problem -- like the expensive video card. That's what's confusing me.
    So, I'm proceeding as if the problem is caused by a file being loaded into memory and I'm trying to disable the items that don't load in Safe Boot Mode one-at-a-time. I just need a specific list of what those items are (and their locations on my hard drive).
    In OS/9, I used Conflict Catcher to do this automatically, but I haven't found an OSX app to do the same. So I'm trying to do it manually.
    Please excuse my layman's terms. Any help is appreciated.
