Question about Philips 36PT842H 36" TV
My television was turned on and was being watched for about 30 minutes when we went to change the channel the picture went blank. My daugher escaped out of the satellite menu and there was no picture. They tried to display the menu for satellite, still nothing. The TV was unplugged, turned back on and the light on front next to the power button blinks 5 times and is blank for a few seconds then blinks 5 times again. I switched satelitte receivers and still no picture or sound
first place to start on this chasss is with a known failure in the horizontal circuit. there is a capacitor 2455 and 2 transistors locations 7461 and 7463 that have caused a wide variety of failures. i would recommend replacing these components before proceeding as they could be the whole of the problem.

It sounds like the voltage regulator in your power circuit. Also you have a capacitor that's going bad somewhere and won't hold a charge. That's why the picture is fine for a while then turns green. Unless you service TV's this one will have to be brought into the shop. Unfortunately it'll cost more than the TV is worth to get it fixed unless it's still under warranty. These days TV's that small aren't worth fixing. You're better off buying a new TV.

You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.
