Picture has started to flicker rhythmically with the interim decreasing over time. It's like a flash at the top of the screen. it started out a few days ago with repeating part of the previous screen image before advancing to the next screen. Like a shadow of the previous screen - a flashback - very quickly - before the new screen appears.

The cables could either be loose or need to be replaced for your TV or the connection ports are broken. The LED lights or the T conn board could be causing the TV screen to flicker.

Defective CCFL backlight may has 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.

Hi...the flickering and the green is the colorwheel going bad. Very common for this model and an easy fix too.

try to decrease the screen resolution. try to 640 x 480 then raise to 800 x 600. for old CRT monitor maybe have a problem with 1024 x 768. if decrease not work, then you might have a hardware problem, you need to purchase a new one. try the test first. maybe you can test with your monitor of your friends first :-), if work, you need to purchase a new one.
