I would replace the entire inverter board. Picking and choosing will cost more.

The set will need to be properly diagnosed to narrow down the problem. You could be looking at a bad inverter, bad CCFL lamp, fault in power supply or main board.

The backlight inverter which is also part of the power supply needs to be replaced. If you feel comfortable you can replace the blown capacitors on it.

Hello.The screen goes black means that the backlights of your LCD is not working.Maybe the problem is the power supply or the driver board of the backlights.They shutdown because there have a shorted parts on the circuit or power supply. Did you try to reset the power and turned on and get a picture or every time that you reset the power it will get a picture and the picture goes black?

it is your HD box. get another one.

Anytime an LCD has a shade of pink, that means the CCFL lamps are about to go out. Now that you have a black screen, I'd say you just need some new bulbs.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
