    I have test my screen, which as the inverter in the screen assembly.

    The whole screen assembly was removed from the laptop and test on another laptop and it worked.

I am facing the same problem. A guy old me that there is an IC on MB that is responsible to power the inverter board...but he asked for 50 pounds for its repair. I am searching for that IC and till that, I am using an external monitor.

Hi:
If you have tested your screen, then the problem is most likely the LCD inverter assembly. It is usually mounted near the bottom of the LCD, is a tiny circuit board, approx 1/2" wide by 4" long. it is what powers up the backlight on the LCD, and they don;'t cost too much, maybe $15...Hope this fixes it!

    If I understand you correctly, you moved the entire screen assembly to test it? LCD, inverter board and cables?

Intermittent video problem on acer extenza 5620.sometimes video display backlight will work sometimes it fails.


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 or appear black.
  • 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.
