Question about Philips 15PF5120 15 in. LCD Television
First you should find out if the image is still there - if it is then the inverters for the CCFL tubes have failed. If they have failed it will be very easy for you to fix them - basic switching power source, probably the power transistor failed.
If not then the problem is either in the connections to the panel or the image processor. If it's in the processor then this monitor is dead - as you know unsoldering a processor involves a very special heat gun and a lot of patience for a very up to chance result. Add to that the fact that it will be almost impossible to find a new processor on its own and a replacement mainboard will cost you more than the tv. Time for a new one.

The backlight inverter has been a common failure for this set. Check the electrolytic capacitors C16 and C17 to make sure they aren't bulged or domed on top rather than flat, and make sure F1 (2.5 amp fuse) isn't open. If these parts are bad, you can replace them and save some money, or if you can find the backlight inverter board you can just replace the whole board. I searched a couple of our parts dealers and was unable to find the board in stock. It may be tough to find one. Good luck!
