Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.

Yes, he means 2200 microfarret (called uf from here on out). Another important concern when buying a replacement is the voltage. You need to get something that is at least 25v. I recommend a 35v or better. Another notable point is that this may not always fix the problem. As with mine, there was also a 1200uf (microfarret) 35v capacitor that was blown. You can tell this because they bulge at the top. I have both of these caps (2200uf 35v and 1200uf 35v) on order and they will be here tomorrow. If I do not post back here then they fixed the issue for me. I suspect that this will resolve the problem. Look for bulges on top of the caps. This is an indication that they are blown. Most all of you experiancing these symptoms will see the 2200uf cap bulging but you may also see others bulging too. If you do then you need to replace those too. No electrolitic capacitor should be bulging at the top so if its bulging its bad, and if its bad then your tv will definitely not work. Have fun.

The power board numbers you need to search for on eBay is 310432847531 or 310432838621 - they are compatible according to Philips.
