Hi All, need some help here. I came home the other evening, turned on my set, then after 5 minutes the picture just went out. Sound is still fine I can change between video sources but nothing on the screen. Not even the volume bars. I'm not getting any led code flashes either. I've tried the 4 hour reset, but still the same problem. Any help supplied would be apreciated.

Re: Sound but no picture
The only time I have seen a Sony set with absolutely no picture and no on-screen menu but no error codes from the front LED, the main signal CXA jungle IC was bad and needed to be replaced. This is something that should only be attempted by a qualified tech familiar with Sont sets.

Hi DiBd. Some electronic components in a tv can go out of tolerance during long periods of inactivity. I think that's what's happened to your set. Some component in the video section of your tv has given up.
Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider
Your set is shorted circuit condition. The power supply is making the noise. Unfortunately almost any of the hi current circuits will do this. If picture went out 1st look for video or hi voltage problems.
Sounds like horizonal output transistor could be over heating. There could be other problems. But I would start there. You can find the part number on the schematic inside the set. If you change it yourself don't forget to use the included insulater. Part should cost between 15 & 20 dollars. You will need make & model # of set at electronic parts store.
Diagrahm inside set will show you location of transistor.
if you are hearing a click and electrical statics when you try to turn it ON, the flyback of the tv is busted there are alot of reasons for that problem lighting is one so dont leave the cable screwed in if ever youre going out for a long time. you can have it replaced by a technician ( flyback). but it would cost you. and im not sure if you can find an orginal flyback considering its 10years old. there are replacement flybacks but quality would not be as good as the original one.
it is best you buy another set my friend it is not worth fixing the money you have for repairs and the cost for components put it together and you will get a good tv free of repair worries plus with warranty.if you get that set fix bam you take it home then about a week it is back in the work shop again.you will have to spend more money.a 10 year old set is not worth to have it repaired.replace it.good luck my friend.
