hi new to the forum
i have a 30"phillips lcd tv its around 2 years old for a while now when cold the tv would click on and off and the volume would go very high then start againtill turned off.
then today it was working fine till about half an hour ago went to turn it on now theres sound but no picture theres a hissing sound just before the screen go,s black
thanks for any advice as this tv is a real pain in the butt.
cheers david
Sounds like two differant problems. The problem with it going off by itself and needing to be turned off could be a common one where a power supply capacitor is going bad or has a cold solder connection on the leads that attach it to the printed circuit board. The second where theres no picture should be a backlight circuit trouble. Could be a fan problem where the lamp circuit overheats and shuts down, again a capacitor in the power supply, or even a problem with the lamp connections on the socket or the lamp power circuit. You should call an authorized repair center to have this set estimated, as it you dont and let the suspected trouble fester, it will get worse and most likly cost more to repair. Let us know how you made out with this and Good Luck.
