Screen blinked and then there was a dark band across the top of the screen


This sounds like one of the back lights have failed. This could be its power supply, and or the lamp itself.

Not all the screens can be service for back light failure. This is design dependent. Also, if you are going to change a back light and you can, it is best to replace all of them at the same time. If not the coloration of the screen will be different from one part to the other. With age the color of these lamps changes a little.

I would suggest with such an old set, I would get one of the newer LED/LCD sets. They are very far improved over the one that you have. Your set will be expensive to service, if it can be serviced.

Acer Laptop Screen Flickers & Jumps


Hello,



Please connect the laptop to an external monitor. If no flickering on monitor screen, from my previous experience, this is more likely loose connection of video cable connected to the LCD. So talk to Acer support again and require the replacement of LCD.

Looks like a black thumbprint blocking 1/3 of the screen. No LED's lit on front of TV. Started as black dots, and filled in almost completely. Initial lamp lasted 2 years. The replacement lamp lasted 3...


It looks like DLP chip is failing. It is installed on DMD board that in turn belongs to optical engine. Issue should get progressively worse. If you look at screen up close - you see that "tumbprint" consist of little small dark-gray squares, some of them flickering.
Cheapest solution - to replace DLP chip. instead of replacing whole optical engine.
This repair have to be confirmed (by running test patterns in service mode first) and done by professional.
Repair could cost aroung $400.
During procedure I would recommend to turn ceiling fans and other air blowing devices off. Single little dust speckle landing on the chip surface will ruing all effort and same amount of labor have to be applied yet again just to get rid of it (been there, done it).
Good luck.
Russ.

Acer screen looks dark?


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

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.

Dark Screen and flickering black screen


I am having the same problem and I think it is the bulb in the TV or the board that the bulb is on. Only had mine for 4 weeks!! Apparently this is a common problem with LG TV's that occur as often as 3 times a year with a minimum cost of £290 just for the bulb!! Wish I had known that before I bought it!

Would recommended contacting the store you bought if from and ask them to repair it seeing as it is so new, I am awaiting the engineer at present!

Screen rolls


Hi,
I'm writing to you on a screen that is rolling and sometimes flickering right now. I've tried 3 different screens on the same outlet, and they all have the same problem.

1. If you have any speakers near your monitor, try moving them away, this might help because they might not be shielded enough.

2. Try another screen, if the problem persists, it may be your power outlet.

3. If you don't want to spend money on a new screen, spend some time looking for a 3-prong grounding adapter.

I used the 3-prong grounding adapter, those little adapters that plug into the wall using 2 prongs, and then you can plug a 3 prong appliance into them on the other site, and it helped make the rolls not appear as often, and not as dark.

I think it is something with my power or the plug I am using.

Hope this may have helped a tiny bit
