Problem with Acer LCD monitor, one third looks ''burnt''

The top third part of my monitor went blank, it looks burnt and the images in that part of the image linger for a while. I have tried the monitor with another CPU and the result is the same, so I know the problem is with the monitor. Tried different cable, same result. I have contacted Acer but warranty has expired. Is there a way to upload a picture? The image is pretty self-explanatory.

I'm thinking that you need a new monitor.
You already satisfied yourself that it is not the computer by putting the monitor on another machine.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Va912b first cuts on with mostly blank but with broken strips of lines from top to bottom and have some together and some with blank seperation between them. then goes blank


joaye, First place to look would be the monitor's "switch-mode-power-supply" and /or the INVERTER circuit. When strange things start to occur with LCD monitor's w/CCFL backlighting, the first place to look would be the internal or external SMPS for the unit. You should be careful in your third use of the word "BLANK". Some monitors will be BLACK and not BLANK! Some will be both BLACK and BLANK. Read more Black screen stuff in my profile and you will understand WHY your unit is behaving like it is and some useful options you and other's like you have. Also visit www.ccl-la.com/badcaps.htm and www.lcdparts.com or YOUTUBE for videos on lcd repair or lcd monitor disassembly FYI DIY type stuff. I'm 12fixlouie on fixya.

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

My acer 9300 when switched on shows a blank screen (black with some faint white back ground) but the process of starting windows goes normally coz i can view this when connected to a monitor whats a miss ?...


If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

You could have an inverter problem, it supplies high voltage to the CCFL backlight lamp or you have a faulty CCFL lamp.

Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

Monitor Problem:


You may be encountering a hardware fault that numerous people appear to be having (myself included).

Get a bright torch and point it at the screen once it's 'gone blank'. Look for any text / images that you'd expect to be displayed.

You will normally see a faint display which shows that the problem is just with the backlights. Unfortunately the inverters for these are built into the power supply (Delta Electronics, model no. ADP-40AF) so you will more than likely need to replace this. It's probably easier, simpler and cheaper to buy a replacement (non-Acer) monitor!
