Sony Trinitron KV-28LS36U no sound or picture, the standby light flashing green and red but if i switch it on a little bit of sound comes and then switches off. how can i repair?


The unit is shutting itself down because a problem was detected internally. When this happens, the standby light should blink a repeated pattern. Please count the number of blinks and post the number here. That will indicate the circuit in which the problem occurred.

Thanks,

The usual cause of this is the sensing IC (there are 2 of them) on the power supply board. Sony usually recommends pulling the board and returning it to them for service.

Sony projecting tv kp-57wv700


Based on service manual info, it cant blinks 7 times as per symptoms, please count again blinks. It can be 5 times.
If its 7 times blink, Horizontal Deflection stopped in this case. If you want to repair it at your own, please let me know to guide you further but it is necessary you should have knowledge of electronics.

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.

I own a Sony T.V. model #KV36HS510, Serial # 9024184,Event# E36002407 and it"s aTrinitron brand name. Like the problems before no picture or sound, stand by light on front of unit flashes. When trying to turn it back on you can hear the power click, like it wants to turn on, but does not.
