This is a common problem on many makes and models of LCD televisions. The backlight is going off intermittently. The inverter which powers the fluorescent backlight tubes is stopping due to inverter protection operating. It is more than likely a defective inverter pcb. It can on some ocassions be repaired but in most ocassions the pcb gets replaced.

Tv has no picture but has sound


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Screen lower half goes black/blank


The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.

TV Picture Goes Black


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.
Thanks to those who posted the solutions
