LCD panel on 6500 (709n) is gray and fading

The LCD panel on my 6500 wireless is becoming increasingly difficult to read. The letters/numbers are light, and in some cases are unreadable. Any way to remedy the situation?

You can access the internal settings of the printer by typing its IP address into the address bar of a web browser. You can get your printer's IP address by printing a WIreless Network Test from the Network menu on the front panel.

HELP! I just got a new HP printer that prints GRAY and FADED COLORS

I just got a new HP Printer, and all faxes are pure black, all copies are pure black, but anything I send to the printer from my mac prints GRAY and colors are all FADED... I have gone thru all the steps with HP and it seems it is some kind of setting in my mac that I am unaware of... Does anyone out there knows what setting(s) I need to get to in my mac to correct this?

Hi tydiva, and a warm welcome to the forums!
When the Print Dialog comes up, click on the Copies & Pages drop down, check settings under those, especially Colorsync & Pinter Settings or Quality.
Which HP is it?
When the dialog comes up, print as/save as PDF, does it look the same in preview as the printer?

How to connecttwo external 19" LCD panels over DVI to MBP

Hi,
Is it possible to connect two 19" LCD panels over DVI to a MBP and run them as a single extended desktop?
I've not been able to find an answer in the many posting and I get the impression its possible, but I'm not sure. I get more doubtful when I start to figure out how to do the cabling (daisy-chain the panels, use a DVI splitter?).
Any help is greatly appreciated!

Do you use this set-up with multiple monitors and the extended desktop?
I ask because I followed your suggestion but at the Matrox site (http://www.matrox.com/graphics/en/cadgis/products/th2go/th2go.php) all the indications are that it only works with Windows. Even the user handbook doesn't reference Apple at all.
It sounds like a great idea, but I'd like to verify it works before spending the $300.

OfficeJet 6500 709n and MicroSoft Office 2010 duplex print problem

I have an OfficeJet 6500 709n and was able to automatically duplex print with Windows 2003 no problems. I upgraded to Windows 2010 and now it won't see the automatic duplex printing. I can only select single page printing and manual duplex printing. Any ideas what I need to correct???? HELP PLEASE!!

Hello,
Make sure the Automatic Duplexing option is enabled:
Enter Control Panel > Devices and Printers.
Right click the printer icon, then click Printer Properties.
Click the Device Settings tab.
Set the Automatic Two-Sided Duplex Accessory as installed and click OK to save the change.
Now Automatic Duplexing should become available.

Purchased a LG FHD LCD panel and broken.

Hello everyone, I am using T520 4242- RU2 model in Thailand. I tried to upgrade my LCD panel from 1366*768 to 1920*1080. I bought a panel in e-bay and I replaced by myself. After few months, it becomes yellowish color on white image. So I removed it and replace default one. Well, I would like to buy a new FHD panel again. Do you know which one is recommend? AUO or LG or Chimei or whatelse...?? if you have recommended P/N or FRU, could you let me know? thanks and best regards,
Solved!

Hi, I have a 3 year old Macbook Pro 13" and I accidentally cracked the outer screen of my mac book, however the LCD panel is fine and works well. Please advise what to do

Hi, I have a 3 year old Macbook Pro 13" and I accidentally cracked the outer screen of my mac book, however the LCD panel is fine and works well. Please advise what to do. I live in India and I have gone to authorised Apple technicians and they infomed me that I will have to replace the LCD panel as well even though it is not cracked, is this really true or can I just change the outer shell? Also they say that they cannot do it in India... can I do it myself at home?

Since it is 3 years old find a local repair shop that can replace the glass Only. you may have to send it out to a Non Local shop for that but there are some that specialize in doiing that on Mac notebooks.
Apple will ony replace the complete screen enclosure with all normal parts included, LCD, Camera, Aluminum housing and glass as one unit. Which is very expensive. Or you could just use it as a desktop system with external monitor and buy a new notebook.

IBook has no backlight even after LCD Panel and Inverter Board Replacement,

I just got hold of an iBook G3 800mhz that works excellently aside from the fact that it has no backlight. Usually, I can figure this stuff out pretty well, and I had some parts around, so I replaced the inverter board and LCD panel. Still no backlight. I reset the PMU and NVRAM, and of course turned up the brightness in System Preferences. I can't figure this out. What else could it be?

Hi Guy,
As Rhonda suggests it's probably the inverter cable. I've repaired two recently both were broken at the hinge point where the cable is wrapped in this silver flex tape. One was the red wire, the other I forget. I diagnosed this by pushing the wires together at the hinge. Once I found the broken one and isolated the point that it was broken I soldered it together and used shrink tube to repair it.

Is there a way to change the color of the answer bubble for the texts? Mine is now in gray and very hard to read

I just updated my iPhone and would like to change the color of the bubble for the text reply. Mine is now GRAY and it is much more difficult to read. The outgoing text bubble is still blue. Can I do this?

Yes. Well, sort of: instead of a "path", set the pen tool to "shape" in the tool properties. Then set the fill colour to transparent, and the stroke colour to the colour you want. You can also set the stroke width.
Not perfect, but at least you can see the path more clearly - the anchor points and handles still remain the default colour. Open the path panel, and right-mouse click the path shape to create a selection based on that shape. The Paths panel menu also allows you to create work paths based on that shape.
Unfortunately when you try to move the handles the black thin outline appears again until you release the mouse button.
This is one of several things that works better in Photoline: in Photoline, once the path is set to a specific colour, editing the path uses the actual colour and stroke width. which is extremely handy for creating path based selection with awkward background colours and/or a high resolution screen. In Photoline the handles and bezier points are also much, much larger, which makes it rather simpler to work with as well - especially on a higher resolution screen. And when selected the handles and points are a clear red with a black outline - again easier to spot and identify. I just works better, in my opinion.

LCD Panel not supported (acpi brightness)

Hi all,
This is my first post, Hello! I have used several distros but this is my first time using Arch.
I have a dell d420 (dual core / intel graphics). I have installed Arch with lxde / compiz.
Things have been going pretty well so far, I really like the distro. However, I am having problems with laptop-tools and adjusting the brightness of my lcd on AC acpi events.
Basically, I have /etc/laptop-mode/conf.d/lcd-brightness.conf configured as follows:
# Should laptop mode tools control LCD brightness?
CONTROL_BRIGHTNESS=1
# Commands to execute to set the brightness on your LCD
BATT_BRIGHTNESS_COMMAND="echo 20"
LM_AC_BRIGHTNESS_COMMAND="echo 70"
NOLM_AC_BRIGHTNESS_COMMAND="echo 100"
BRIGHTNESS_OUTPUT="/proc/acpi/video/VID/LCD/brightness"
Further, laptop-mode is running and set up as a daemon.
The problem is when I plug/unplug the power cable the brightness of the panel does not change in the way I would expect it to. Sometimes it does not change at all, sometimes it gets brighter on battery than it does on AC!!! The brightness keys on my laptop work fine (however, they are I believe prgrammed into the bios and rely on no software to adjust the panel.)
Things I have installed / setup:
acpid
acpi
laptop-tools
I have noticed that there seems to be a problem recognising my panel, when I do a
cat /proc/acpi/video/VID/LCD/brightness
I get the response:
<not supported>
Also:
cat /proc/acpi/video/VID/LCD/info
device_id: 0x0400
type: UNKNOWN
known by bios: no
I think this is the problem, as laptop-tools and acpi seem to be configured correclty apart from this issue. Any thoughts?
Many, thanks.

OK, it looks like others have had a similar issue with the NVS 3100M adapter. I found this prior post:
I followed the advice there and installed the 32 bit A08 driver that I found here:
Now the backlight works fine on startup. Unfortunately my system has lost some other small functions and seems a bit slower, however, at least I can now work while I travel.
It's a bit disappointing that newer drivers seem to break my computer. I'd very much like for that not to happen.
Some steps of this, like updating the BIOS and installing the driver were a bit complicated, so I'm happy to give advice on how to do that if anyone needs. In the meantime if anyone has a better way to fix this, I'm keen to find out.

HP Officejet 6500 709n network scanner & fax problems

I have a HP p7-1298cb desktop computer that came with Windows 7 and I installed the HP 6500 709n to it successfully. Have a home network with several computers and they all use the printer. The printer was connected to the network with and RJ45 cable. I reciently upgraded my HP desktop to Windows 8 and only that computer has problems with scanning and faxing to this computer. I reinstalled the software (OJ_AIO_6500_E709_Full_Win_WW_140_408) several times HP desktop using wireless connectivity, wired connectivity and USB connection. Only the USB connection works with all of the printer functions, both wireless and wired only can print. The errors I get with the network connection are the following:
The scan cannot be performed because another program or computer is using the networked HP image device. Try again later. (from HP Solution Center)
Scan communication problems detected. You may experience limited functionality when scanning from your printer to your PC.
If you are using firewall software, verify TCP port 9500 is unblocked from your PC to your printer at 172.17.1.36.
If you are using firewall software, verify TCP port 9290 is unblocked from your PC to your printer at 172.17.1.36.
To fix the issue(s) try to power your printer off and on. (This message is from the installation)
I have added those ports to my firewall and it doesn't have any effect, I also turned off the firewall on the HP desktop and it also has no effect.
I have searched this discussion board and have found similar issues without a resolution.

Hi Moondoggytoo,
It looks like you need to do a full scrub of the printer software and re-install it. An issue like this can happen following an upgrade to Windows 8 when a printer was already installed. I have enclosed steps needed to take that will clear out programs that are no longer needed. This should allow for a clean start with a new install. Let me know how it goes.
Good Luck!
These steps should only be used on a Windows 8 computer.

Weird scratches in lcd panel (23" acd)

Well, i'm back. This 23" is the third one I got from Apple, the two previouso one's exhibited ghosting & the pink issue.
This one doesn't have these, only some backlight leaking when viewing black images fullscreen.
The thing is, the build quality on this one is below par, I think.
1 - If I tap the lcd panel itself on the right top corner, it moves about a mm. It's a little loose, and I can 'push' it inwards about 1 mm.
2 - There is 1 stuck pixel (red) in the bottom left corner, that doesn't bother me that much actually.
3 - There seem to be 2 scratches in my lcd panel. I can't describe it very good, but a picture will do the trick. Here are 2 of them. They're not stuck pixels, the shape doesn't match up right.
http://users.skynet.be/bk318948/screen4.jpg (the largest scratch)
http://users.skynet.be/bk318948/screen2.jpg (small one in the bottom)
Should I take this back again? The build quality doesn't resemble my 2500 euro I paid for it back, in july 2004.
This is my third replacement though, and I don't want to go through that process again, so either they give me a complete refund, or they compensate me in any way for this lower build quality.
Am I overreacting with this issue or not?

What's the latest Jan. 2010 spec LCD panel model #? (e.g. 9CBD, 9CA0, etc.)

Just wondering if anyone who has a 2010 assembled 13" MBP or recently warrantied MBP can confirm the latest Apple display spec model # (e.g. My MBP was built in Sept.09 and has a 9CBD panel) that is being used?
Got the dreaded light leak developing on the side and hinge edges of my MBP -- but considering that my colours/calibration are pretty much bang on for my eyes as well as the fact that I've painstakingly applied an Anti-Glare film 100% free of lint bubbles LOL -- my conundrum if the latest spec'd panels are really any better or if it's still a lottery on whether you get a good panel if replaced under warranty. The last thing I want is to go backwards in quality!
Also if you've gone through the warranty process I'm curious on whether you have any say on whether it is another 9CBD that goes in or if you can specify to them that you're only satisfied if a Jan. 2010 9CA0 (or whatever # it is) is put in?
I am planning to wait to see if Apple quietly updates the LCD panels in the MBP line at the Jan. 27 iTablet/iPhone OS4.0 event before taking it in anyways, but hopefully someone can shed some light into how Apple have been going about dealing with the light leak issues. Thanks again.

Thanks for your kind cmments matrixxzero. I agree rockykoston I will replace my keyboard eventually myself too, with all the stories here I'm terrified to hand my laptop into service, apart from not having the spare time, Idon't want it to come back scatched, damaged and/or unfixed. That doesn't augur well for Lenovo guarantees. I am fully cpable of servicing it myself but many customers aren't and shouldn't have to.
As I say the other issue is model lines. Our Chinese friends have proven they can maintain quality and innovate now but their shere manufacturing muscle means it's all too easy to have too many models and too many variants with too much crossover.
Why drop a great design like the Z710, only let down by a middling to poor Nvidia chip and introduce new 17.3" models with absolutely no maintenance covers and sealed batteries!! They should have upped the Nvidia chip (the same as the Y50) and a better WLAN card. Same with the 15.6" models - evolve the Z510 to have a case like the Z50 but the same or better components again. Similarly the Y50 should have been an evolution of the Y510 not a step down.
Lenovo has definitely gone cheap in the upper end of the consumer range, when they needn't as there are tons of cheap laptops from the brand.
Most of the reviews I came across for the Z510 described it as having very good build quality and since I changed laptops three times from the same store within my purchase period I had chance to compare closely, with at least Toshiba and Acer. I would not agree with these reviews it's OK but not great. The metal upper case fooled me a bit but it's less sturdy than a cheap i3 HP laptop it replaced. Again for around a $1000 it should be better.

Some LCD panel info

Hello all,
Like quite a few people on this forum, I recently purchased a new MB 13" aluminum and have been very disappointed in the quality of the LCD panel. In particular, I feel like the viewing angle on this display is significantly worse than my old Thinkpad X41 tablet, which is going on 4 years old. So, I went in search of some technical information, which I figured I would share...
There are three main technologies for TFT (thin-film transistor, or "active matrix") LCD panels. Twisted Nematic (TN) is the most popular type of panel because it's cheap to manufacture and has very fast response times. However, image quality on the TN panels is the worst of the three technologies. In Plane Switching (IPS, S-IPS) is the best quality panel, but is expensive to manufacture and has relatively slow response times. Vertical Alignment (VA, PVA, MVA) is a mid-range technology, somewhere between the cost of TN and quality of IPS.
This site provides a very nice explanation of the pros and cons of the three technologies:
http://www.pchardwarehelp.com/guides/lcd-panel-types.php
The vast majority of displays (notebooks and desktops) use TN panels because it keeps costs down and because the fast response times are better for games and movies. This trend was probably reinforced by the explosion of LCD televisions: for TVs, good response time is critical and vertical viewing angle is totally irrelevant.
There seems to be a consensus that all three lines of MacBooks use TN panels, but possibly with different levels of quality. I could not find much information on what causes quality to vary between panels that use the same technology (i.e., why is one TN panel better than another.)
Most IPS panels go into high-end displays, such as the Apple 30" Cinema display, for applications where image quality is crucial. It turns out -- and I did not know this at the time -- my old Thinkpad X41 is one of the few notebooks ever made with an IPS panel. I suspect they chose this panel because a tablet PC must be reasonably readable from a wide variety of angles (for example, laying flat on a desk), or it's useless.
So, maybe we just have to wait for a MacBook Tablet...Jobs, are you reading this?

SZGuy, nice digest of LCD info. You had me with every point except the one about viewing angle being irrelevant on a television. How so? When a family sits distributed around a room, all are entitled to a good view of the telly.
Every TV of at least 32" or larger uses a wide viewing angle technology panel. IPS and PVA are still hugely important in television and I don't see that changing soon. In fact, it is TN that is irrelevant in the world of TV.

2005 iBook G4 lcd display has turned streaky fuzzy pink and blue

Boot up laptop screen looks fine. Goes to sleep, wake it up, screen is now weird. Gone fuzzy, no true colors, looks streaky, pink and blue. I rebooted, no change. I'm plugged in, so it is not a power/battery issue. Since I've had this since 2005 I suspect I have to replace the screen, but heck I don't know. Can an expert help me here? I've got a screen shot to share, how do I upload it?

O&O,
I've got a screen shot to share, how do I upload it?
I think to upload here you have to have a membership. I just upload pics on PhotoBucket:
http://photobucket.com/
It would help to see a pic.
This is from the service manual for the 14" 1.42 GHz mid '05:
"xScrambled or distorted video
Check for video on external display.
• If video is fine on external display, replace LVDS cable.
• If video is scrambled or distorted on external display, replace LCD panel."
That last line is a bit extreme AFAIC. I suppose a bad display could cause the GPU to put out distorted video. So if it was me I'd unplug the LDVS cable and then if the external display cleared up then I'd replace the LCD panel.
The 1.42 also uses the ATI Mobility Radeon 9550 4x AGP I have one of these in a 1.33 12" and it went bad. My normal repair is to swap in a good chip from a PC laptop graphics card. Unfortunately I can't find a cross reference to that chip being used anywhere else but the iBook 1.33 and 1.42.
after it was sleeping for 3 hours and the screen is bad again
Have you tried resetting PMU? Does any of this involve moving the screen? That's one of my checks for a bad LVDS.

MegaPC 180 - Programming LCD Panel

Hi All,
I recently built my MegaPC180 and what a lovely machine she is too!. My old machine sounded like an aircraft taking off!, this is nice and quiet with lots of mod-cons in a SFF barebone.
One thing I'd like to take advantage of is the LCD panel at the front. I know the PCAlert tool uses this, and by the looks of things it doesn't make any direct calls to the dll file which I thought may be the API for the panel.
I'm very familiar with C++ and VB and want to use the panel in several utilities I've created.
I found the msidrvif.dll file in the Program Files\MSI\Common\Bin folder. It exports the following functions...
DIF_CheckHardware
DIF_CheckMBType
DIF_CheckModel
DIF_CheckOEMModel
DIF_FS_SetAPStats
DIF_FreeDrvIF
DIF_GetDriverSelect
DIF_GetModelName
DIF_GetVideoFormat
DIF_InitCheckDevice
DIF_InitDriverSelect
DIF_InitDrvIF
DIF_RD_AudioOff
DIF_RD_AudioOn
DIF_RD_CheckLock
DIF_RD_GetDefMem
DIF_RD_GetRemtKey
DIF_RD_LMute
DIF_RD_PanelOn
DIF_RD_QueryLockLevel
DIF_RD_RMute
DIF_RD_RadioOff
DIF_RD_ScanFreq
DIF_RD_SelHWMem
DIF_RD_SetArea
DIF_RD_SetBand
DIF_RD_SetDefMem
DIF_RD_SetEQ
DIF_RD_SetFreq
DIF_RD_SetHCC
DIF_RD_SetHWMem
DIF_RD_SetLCDTime
DIF_RD_SetLEDPanel
DIF_RD_SetMono
DIF_RD_SetSIJ
DIF_RD_SetSNC
DIF_RD_SetSRS
DIF_TV_AudioOff
DIF_TV_AudioOn
DIF_TV_FineTune
DIF_TV_GetFreeScanStatus
DIF_TV_SetChannel
DIF_TV_SetCountryCode
The unfortunate thing is....I don't know the syntax of the functions, such as params, and returns.
I'm hoping someone from these forums, or from MSI technical could tell me the declarations so I can get over this hurdle?

Hi Andy,
Perhaps you have already read the posts regarding control of the LED panel. Anyway, I have done a little research myself and was able to obtain the specifications of the Bluebird VL+ controller which actually controls all the pc-off functions (and the LED panel). In theory this controller can perform more tasks than MSI used!
I also contacted Liteon Optoelectronics for the design specifications of the MSI LED panel. Unfortunately they are not allowed to release them (prohibited by MSI). However, I found the blueprints of another LED panel from Liteon with a comparable product code. I think it is likely that Liteon used the same design basics when building the MSI panel.
You can send a p-mail when you are interested in these .pdf files.
