Re: hitachi hdtv flat panel tv no soundand no picture
Most of the case horizontal output transister failure cause these type of problems. Additionally flyback transformer failure also leads same problem but it depends upon aging of the tv. Whatever it is it could be fixed by service Technician only.

For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
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.
