Try removing the horizontal output transistor, and see if ther 135 comes back up. If it comes up a litle and shuts down replace the horizontal output transistor and the flyback transformer. But I must warn you of the extremly high voltage thats inside this set whn its even unplugged. Be carefull!! Good Luck

If lamp light is on at tv front then replace lamp as existing lamp sounds dead/ broken.
Lamp replacement procedure would be written in user manual of tv.
And if lamp light is not on but standby light is blinking then let me know how many times it is blinking to find out problem cause as standby light blinking is an error code.

Our sony will not turn on, we hear the click but nothing.

The 7 blinks usually indicate a high voltage problem (voltage too high). It can be a simple regulator problem or something more complex. Please update this to confirm your model as KV-32FS120 and some indication of whether or not you wish to attempt the repair yourself.


KV27S42 dead - 4 blinks

the +13 and -13 are generated by the flyback transformer as well as the 200 volts. the 135 is your B+ voltage and sould be there at start up. check the HOT and the Flyback. if there is no 135v check IC1751 on the C board sometimes if bad it loads down the 135v line. and can give a faulse vertical error.

I'm not certainly sure how many time the led blinking ?
