Hello,

The problem with the television is the lamp. It is faulty that is why the screen turns wavy in minutes.

The solution to that is to replace the light and your television will be in good condition once again.

Take care

It looks like you have a convergence problem here, probably a defective convergence IC.

You have problems with your power supply filters. I'd suggest you to change the mainfilter, that is the capacitor just after the ac rectifier and the b+ filter, that is the capacitor at the output of the smps, and then vertical filter and video filter. These are all capacitors with higher microfarad ratings, if you are not much comfortable, it's better to get some help from someone who is familiar with these. Pay attention not to reverse the polarity when changing the capacitors.

this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.
