Tv won't turn on


High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. 7 blinks to standby light indicates this. If you wish to get some details, http://electronicshelponline.blogspot.com/ Pull up older posts.

I had similar problem with my panasonic tv, turned out to be a fan failure causing power supply to shut down due to overheating, Also could be a capacitor fault in the power supply.

Sony KP-51WS500 will not turn on


I believe the problem is either in the G board ( power supply) or the D Board ( high voltage) as the 3 blinks indicate the G board, and 7 indicates the D board and 6 indicates the +5 line a and b boards. So with that many codes its most likely the G board (power supply) You can get a new replacement G board at the following link which comes with free tech support to help you plug the baord in which is very easy. Its listed under the Sony parts category and its the A-1316-566-A sony G board, Here is the link.

Sony Triniton Wega Model KV 32HS510. After pushing the power button,the tv starts to power up, then the standby light blinks 7 times then pauses before blinking 7 times again. It continues to do this,...


This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.
