The convergence ICs need to be replaced there are two of them they are both STK392-120 and you will also need about four of the 6.8 ohm 1 watt resistors also. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can do the repair yourself. Here is the link.

I have a phillips 50pp920217 tv and the problem is that one lens or lamp its burned. AT the bottom the pictures has a wave and shadow of color red.


Sounds like some of the coolant has been lost. Refill with the same glycol based coolant as original.
