Question about Philips Smart 25TS54C 25" TV
I'm helping a friend trying to repair their tv. It's a Philips smart series 25ts54 c122. A part on the board has burned up (It's blue-green and assuming it's a capacitor) the position on the board it C506. Unfortunately it burned up enough I can't get any details from the piece. The TV started to smell funny and then smoke started coming out so they unplugged it. Later when they plugged it in, it wouldn't turn on but was making a quick ticking sound and then started smoking again. I removed the burn part and the TV now turns on and works without smoking. Obviously the parts there for a reason and would like to replace it but I don't know exactly what c506 is. Any help would be appreciated. I was told that the C506 was a 820pf 2kv capacitor and I've seen on other posts that they recommend replacing it with a 820pf 3kv capacitor. So I replaced it and and now the TV turns on and I have sound but now I only get a horizontal thin line. What happened? It was working OK without the capacitor at all and now it won't work with or without the capacitor - just a horizontal line in the middle of the screen. What should I be looking for now??
Solder the leads of the vertical output IC. Should be done on
every repair as prevent maintenance.If that doesn't help,then
scope the vertical signal starting at the jungle IC.Check B+
voltages as well.If good,check B+ voltages at vertical output IC.
Missing? Troubleshoot power supply ... present = replace IC
Use original NAP part # , no generics..........................T.
Note: C506 is a shaping capacitor.When it burns,it usually
does no harm to other components.Also,while increasing
the voltage rating does no harm, I have not had any recall
of the dozens completed thus far..w/820P/2KV........T.

Try to replace the original one capacitor with the best original specification. Don't do any experiment it might be damage the flyback of the TV screen.
Hope this will be helpful.
