Sony tv wont turn on, standby light just flashes

Wont turn on Sony-KV27S46 27" TV, Chassis BA-4D, made July 1999. TV Set is dead - no picture, no sound. A relay like click is heard when the power switch is pressed. It clicks again a few seconds later when the relay(?) drops out. Every 6 seconds the red standby light flashes 3 times. Nothing else glows inside set. Looks like a common problem. I would like to fix myself but do not know where to start. I have a Sams Photofact and lots of soldering experience. I would greatly appreciate any help. Larry

Check for an open resistor on the power supply, it is actually a fusible resistor, (white) if open, then check the converter, some sets have two separate and some have it as one. it will be on a heat sink on the power supply. if shorted then check for a shorted horizontal output transistor and repair cold solder joints on the horizintal drive transformer which is the real cause of this problem

Standby light continuously flashes with no picture or sound


count the number of blinks; you may have to unplug the set and try to turn on again--if it does not blink in a sequence(3 blinks, a pause etc) the set is in shutdown and many things can cause this.

I press the power button and hear the click but no picture appear


Unplug the TV Remove the cover wait until the TV cools then plug in, turn on and, it should come on... if it does; purchase a computer fan to cool the chassis of the TV wire it into the 12 volt side of the power supply and, install the cover

Sony Trinitron standby light flashes but no picture.


It is possible that the main power supply, and or the high voltage section is failing, and can function on the edge of specs after it has warmed up for a while.

I would be considering a new set rather than invest money in to it.
