17" studio monitor inverter board

I have a 17" studio monitor model M7649. It has started blinking, 2 short and 1 long, indicating the inverter board is bad. The monitor has also gotten darker. Any idea where I might find a reasonably priced 922-5534 inverter board, no luck on eBay.

This means that some backlights have gone. The flashing indicates that the logic board has detected this failure. Replacing the backlights usually makes no sense, and in my opinion your inverter is still in a good condition.
Go buy a new monitor with LED backlights. It consumes less power, gives you more screen size for less money and a better color space.

Monitor HP zr24w inverter board

Two tranzistors gets burned on inverter board inside my hp zr24w monitor. There is probably no chance to repair the inverter board. Is there any option to buy the inverter board from HP?

Hello niio,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that you have some transistors that have blown on the inverter board on your HP ZR24w 24-inch Widescreen LCD Monitor and you are looking to see if you can purchase the inverter board. Unfortunately, the parts that you can purchase for a monitor are very limited and the inverter board is not one of them. I am providing you with a link to what parts are available for your monitor through the HP Parts Store. The only options I can see for you is find someone who is selling the parts privately online or purchase yourself a replacement monitor.
If you decide to purchase a replacement monitor you can contact HP Technical Support for replacement options.
I would like to thank you for posting on the HP Forums. Have a great day!

Disassembled my Ti 1ghz/867mhz (w/DVI) and there's no inverter board? What?

Hello fellow travelers. My ten-year old son and I just finished disassembling my Powerbook G4. It's an odd model. It's got DVI. It's got GB ethernet. It's 1Ghz. It's got the vents of one model and the DVI of another. It's neither Mercury, nor Onyx, nor DVI. What the bleep is it?
It had all the symptoms of a bad inverter board. I'm a pretty good trouble-shooter. So, I ordered a board for the DVI model. Heck. It's got DVI. Just finished taken the entire thing apart as per ifix it (http://www.ifixit.com/Guide/Mac/). Guess what?
I see no inverter board.
Is there a model G4 Powerbook that doesn't have an inverter board? If so, then what the heck explains the "bad inverter board-like" symptoms such is "monitor image viewable with a flashlight from behind the apple," and "intermittent monitor working (mostly not working)" and "runs an external monitor?" not to mention the fact that I believe AppleCare replaced an inverter board (or so I thought) a few years ago.
Are there G4 Ti 15" models that don't have inverter boards?
Has an alien descended and removed mine? Am I losing my mind?

If poltergeists were the problem, you'd find rocks and smashed ashtrays and potted plants strewn around inside your Powerbook, along with tiny video cameras planted there by parapsychologists. That's not the issue.
These are two-dimensional aliens. They turn sideways when they see the camera; that's why you can't capture them on video. It also makes it very easy for them to slide in and out of the Powerbook through the vast empty spaces inside the Titanium atoms - not to mention the added efficiency of space travel without burdensome extra dimensions to scrape against all the ones they have to pass through to get here. Instead of thinking of them as a problem, consider what a lot of trouble they've taken to cross the universe just to inhabit your Powerbook, and try to make their visit more comfortable. You are an ambassador, or at least a deputy assistant chargé d'affaires, for all of humanity. Step up to your responsibilities!
Because the hard drive in a Tibook is so easy to get at, I suggest removing yours (with its flex cable)from the machine and then seeing whether booting from your external drive and/or optical drive goes any more smoothly. If there's no change, put the HD back in and remove the optical drive, then test again. I don't recall whether we've heard that a problematical CD/DVD drive can interfere with startup from another source, but it's definitely possible for a wonky hard drive to interfere with booting from other sources. Lastly, remove both drives and see whether you can then boot consistently from the external drive. If not, and if you're confident of the FireWire cable you're using and the external drive itself, then I'm afraid you've come down to the logic board and the aliens. They may just find that board really homey, so if you replace it, please keep it in a warm, dry place and address a cheery greeting to its occupants each time you pass by.

Reed switch versus Inverter board

I need help....
My display has quit working and the screen is black. I've read so much about this my brain is shorting out and now i need clarification.
Here's what i've done:
Took it to apple store - they denied my request to get it fixed even though im still under warrenty. They said they found liquid residue and declared it my fault - Tier 3 repair - +700$
They wouldn't identify the issue because it's my fault - meaning they wont put time into finding the cause becasue its not covered by warranty - meaning i have to pay to find the cause!
So, I've read the forums etc and determined its the inverter board because:
--I can use an external monitor perfectly
--There is no sleep function disorder - even when using an external monitor i can close the ibook and it sleeps ( ext. monitor turns off) and when re-opened,it turns back on without any issue.
So, i ordered a new inverter board - replaced it in 15 minutes (quite easy to do) by taking off the back panel of the display. Turned it back on and NOTHING!
Now, the inverter board i ordered was ONLY the board, no new cables. I have a feeling that the cables are pinched, worn and thats the issue.
I need answers for the following questions:
Could it be the Reed switch?
Do the inverter board cables only come with the reed switch?
Would an external monitor work perfectly if the reed switch was busted?
Do i need to take apart the entire body of the laptop to replace inverter board cables?
Any links to HOw-to's would be great.
Thanks for listening!
Why is it that PC's mostly have software issues and Macs mostly have hardware issues? Cant they form like Voltron and give the consumers what they paid for??

When my older iBook required services performed by wegenermedia.com
the cost was about sixty dollars plus parts; and while the computer was
open in their shop, other updates could be done for just the cost of parts.
Since their site has contact information; they reply to phone, email or slow
mail, it is best to ask questions direct and see what kinds of expense may
be involved in an out-of-warranty (but authorized-level of quality) repair. As
the company also has most if not all parts for many portable Macintosh
computers in stock and knowledge to repair them, they are a good bet.
Your iBook, if a 14" and running 1.33GHz processor, is next to last version
of that model, as the last model was 1.42GHz; while the 12" was 1.33GHz.
Mine is a mid-2005 model, and of the last ones made; bought direct online.
It still has AppleCare, but is not really seeing a lot of use due to weather
and lack of proximity to much indoor environment, away from my desktop.
Submitting a computer through the US Mail can be a safe bet, as an alter-
native to FedEx or UPS, etc; if that is what works best. Did for me, since
my mailbox is inside a warm post office. The delivery services have been
known to leave parcels outdoors in foul weather; or in their trucks undeliver-
ed for a week after they should have been received. I've gotten broken Macs
through FedEx. An iBook is fairly easy to make a padded container for, to
send it in; and then slide the whole thing into a 'flat-rate priority box' that you
can get ahead of time from the Post Office. Don't expect to see the box
when your iBook gets returned; I made a nice box, but didn't get it back.
Good luck in however you have to deal with your poor iBook's situation!

Digital Studio Monitors (speakers). Control?

I have a pair of Roland DS5 Digital Studio monitors.
Their are connected to the digital out connection of the G5.
I do not have control from the keyboard "volume keys".
I check the system preferences (audio),
I get a massage that stated that "The selected device has no output controls" ???
Well, why I can not have control over the speaker from the keyboard?
The way I have control is from the FCP audio mixer, which I forget to put the master back to "0" before I export a project. I dont think the audio mixer was made for that porpuse anyhow.
Any suggestions beside buying a external digital mixer?
Thanks.

Thanks for you reply.
I sent a feedback suggesting the addition of a very simple volume control. Digital volume control works with QuickTime, iTunes, iMovie, and so on, except FinalCut that does not have one. It's been done. Adding such a simple control improves overall usability and connectivity. More options.
I use a mixer and a capturing device when capturing. I do not see the point of having to route the audio through a mixer if I am just editing. I also do not use capturing boards since all my work is in DV and input/ouput is done with bi-directional converters (datavideo DAC-10). Can you suggest when is desirable to monitor through an external mixer? Thanks.

Inverter Board -how to replace on Powerbook 15 Alum

Please offer directions online-
I have the Inverter board to replace on Powerbook 15 Alum

My display was replaced on this laptop but the display only shows very faint images unless i put a flash light on the back of it or at an angle. Hope it is only the inverter board.
it does work fine with an external monitor so i have alot of hope.
thanks so much,

ifixit does not show you how to crack open the display cover. Anyone know the address of a site that does?

Studio Monitors - what to look for...

I'm going to say this right now - I'm NOT asking "hey, whats the best studio monitors I can get for x dollars." That's not what I'm interested in.
What I AM interested in is what TO look for, and what NOT to look for in buying a new set of stereo monitors.
I've decided I'd like to upgrade my studio monitors. I'm mixing on a pair of Event TR8 XL monitors - they're great, but i know there's better out there. I spent about $600 on the pair.
At this point, my limited knowledge of monitors only allow me to assume that more expensive means better, but I don't understand WHY, or what to look for. So, my question is this. What is more money buying me? Are there brands that are more or less reputable than others?
I'm really looking for general, or specific, advice on shopping for new monitors. Help me make an educated decision, there are too **** many monitors out there to choose from.
For what it's worth, I'd like to keep it under 1k. I'm interested in active near-fields, good for mixing, with decent clarity and few gimiks. Granted, nothing beats getting into a GC and listening to a few (which I intend to do in the next day or two), but I need a little more to go on when I take a look at these in person and listen to some of my mixes on them.
Thanks!
Chris

To add to the previous poster, I have a pair of old NS10's and I use them because I'm used to how they sound and how their sound translates to several other of my references, i.e. my SET/Bottlehead listening system, my car CD player, my table radio. One reason a studio owner would buy say Genelecs or Mackie HR 824's is because they have become somewhat of a standard and like the NS10's of 15 years ago, people know what they're getting once you're used the way mixes translate from them to other systems. That being said, get the Mackies, or Dynaudio BM5A's. Both those seem to be widely accepted and studio proven. That's a good place to start.

Why am I getting an intermittent buzz with preamp and studio monitors?

I've just gotten rid of my desktop computer speakers which plug into the mini-headphone audio out on my Macbook Pro (i7, 2.66, mid 2010). Instead, I've connected via firewire 800 to an older 8 ch Presonus Firestudio Project preamp, and have connected a new pair Fostex powered studio monitors to that for my audio (and scratch recording). When I first start playing music in iTunes it all sounds great. But after a while, I'l start to get these periodic loud electronic buzzes. It's not just in the background, it actually will cut off the song to make the loud sound for a brief second. Over time it will become more frequent, and at one point it got to the point that it was just a constant buzz, no audio at all. Unplugging firewire stops it. Since there are a number of components, I'm not sure what is causing the problem. Can anyone help?

The update didn't apply correctly, which will be typically due to an interuption within your setup. You will have to connect to iTunes via micro usb to restore.

External Studio Monitor??

I read the most recent thread regarding this subject but, suppose you are equipping a studio and money is not really that much of an object, then what would you guys suggest as a large screen external studio monitor. Currently we are using a professional JVC CRT monitor that really has worked quite well, just need something that will support the widescreen aspect ratio and will impress the client.
Thanks
John

If money is no object, get a very accurate, professional CRT monitor for critical monitoring and a larger, high-end presentation monitor/TV for comparison purposes.

Where is the INVERTER BOARD located in a 14" iBook G4?

Please please somebody help me who knows what they are talking about! I am trying to replace an iBook G4 14" 1.42 inverter board and cannot find it in the machine?! Thanks to whomever can lead me in the right direction!

Excellent! Thanks for pointing that out to me. Unfortunately, I replaced it and it did not fix my backlight issue! Do you think you could give me your opinion on what the best possible fix is. The LCD is in fact on and displaying the image, but is dim. I tried all of the simple tricks in the book if you know what I mean, but which do you think is most likely the issue:
1) The LCD itself
2) The backlight bulb
3) Inverter cable attached to display
4) Something on the Logic Board
Thank you for your time and wisdom. If you do chose one of those, explain what you would do as best as possible. It may be something else, but it is doubtful. I mean I could replace the entire display and it is fix (takes care of 1-3). If that does do anything, then we know it is 4.

HDMI cable/adapter causing feedback interference in studio monitors

Hi I just bought an HDMI cable/adapter to connect my MacBook Pro to my LCD tv and as soon as I connect my studio monitors through my MBox interface, I got really loud CPU feedback through my monitors. Any suggestions? really trying to have a nice studio set up here lol

Thanks for trying to help me out, rsannie. I had actually figured it out earlier, didn't get a chance to post. Under Sound, click Recording tab, click the device, click Properties, click Advanced tab, uncheck Enable audio enhancements. This was what was causing the interference/feedback type noise.
Just for the heck of it, to get better acquainted with the settings, I went to where you suggested but could not toggle that feature on/off. This feature looks like it deals with the external mic (the ones by the webcam) and not from a source fed through the minijack anyway.

I've acquired a nice 15" Apple LCD TFT studio monitor and would like to use it with my G4 but have found that the connections are incompatible. Are there any adaptors i could get to resolve this issue?

To get the connector terminology, take a look at the first page of this illustrated guide:

Buzz/hum when connected to krk studio monitors

ok so i have an imac (3.06 ghz intel core duo). i had a klipshe 2.1 speaker system connected with no problems. then i bought a pair of krk rokit 6's studio monitors and just have a whole lot of humming now. so far ive connected headphones to my imac and no hum.... connected my ipod to the krk's and no hum..... connected my krk's to my macbook pro (while it was plugged into the same outlet as my imac) and no hum..... bought a m-audio fast track and connected the krk's through that to my imac and still it hums.... what gives? please help. thanks

Shawn, I am getting a 1 KHz whine through Behringer Truth monitors using M-Audio USB Fast Track Ultra audio/midi interface with an iMac i5 27-inch with LED monitor. The whine occurs continuously from the moment I open Logic Studio or iTunes, when the output is routed through the Fast Track Ultra. The whine does not occur when I use the imac output to imac's speakers. I also get an electronic scraping noise when I use the blue tooth connected magic mouse. I have installed ferrites on the monitor speaker wires with no reduction in the whining noise or electronic scraping noise. I have also ordered the USB with ferrite collar to see if the connection between audio/midi interface and the imac is the source of the noise. I am considering a Hum-X, as well, but I am getting into serious money taking stabs at a problem for which there ought to be plenty of competent technical support. The fact that this whine is at 1 KHz and not lower suggests that I am not suffering a typical ground loop. I am a former Pro Tools user who never had a hum or whine from my Digi and G4, which I am seriously considering recomissioning so I can make music again. I am spending way too much time and money making educated guesses and trying to diagnose a problem that all but kills the utility and purpose of this new system. I too am calling on all great engineers to step up with a diagnosis and solution.
