You could have a faulty inverter or a CCFL lamp, To determine if you have a LCD screen, inverter or video card problem, read this and follow these 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 the monitor up first then the laptop, 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.

After the TV has been on for about an hour there is a clicking noise and the picture goes fuzzy on each clicking noise, this lasts for a few minutes, then the screen goes black for about 5 seconds and the picture comes back, this process is repeated about 5 or 6 times and sometimes the problem goes away or the clicking continues but last nite for the 1st time, the picture went black and never came back. This morning I turned the TV on and everything was fine until about an hour later and the same thing started all over again. Is the tube going bad or what? Thank you in advance for your response. Les
