Question about Sony KV-32S26 32" TV
I'm having a problem with my old TV, which I had been trying to switch on the button the light tick flashed three times and gone off again... Is there a way round to this to make it work again? I had the problem before - by keeping pressing it every now and then it's finally stand to standby light and switch on by remote control, but now i couldn't make it to standby ever since... I'm thinking to take it to the TV repair guy but he asked for £50 upfront fee for an hour work to search the problem(!?) I thought myself (what a completed rip-off!) so I have been searching this internet website for SOS, and come to this..... hopefully someone out there can help me out, and point the direction to fix the TV alive again...? Regards PAUL
Paul first off, how much experience or training have you had repairing tvs?? None?? Ok Paul, theres Hi- voltage and X-ray radiation issues that you must know to work on these sets because of the hi voltage these sets store inside them EVEN when they are unplugged. Now its great you wanna fix this your self. But Paul, These sets have no user serviceable parts inside them that you can test such as tubes. Everything is soldered in and most of the time you can't just see something thats bad. You need special test equipment to trouble shoot these solid state sets. Now if you are a tech then the first thing I would check would be the horizontal output transistor. If thats shorted, then order that as well as a flyback transformer to replace at the same time.. If the transistor was'ent shorted then I would look at the solder connections on the horizontal driver transformer and see if a drive waveform was getting to the base of the horizontal output transistor. Then if all this looked good I would look at my switching power supply to see if the voltages were being loaded down when the set was being turned on. Paul do you see my point??? Good. Please pay for the est., as its better then getting your self killed over a few bucks!!! Good luck
