    No Picture no sound. Stand By Timer Light blinks 5 times on and off, then repeats. Sony Model #KV27TS27.

    We also have a Sony Trinitron 27 inch model number KV-27S45. T.V. comes on, but the picture just flickers, sound is okay. The Standby/Timer light is flashing 4 times and then the T.V. shuts itself off. We also tried to unplug it and waited, plugged it back in and it does the same thing. Help! We aren't comfortable with working on the "guts" of the T.V. and we really love this set!

    Confused and Sad!

Please update this with the blink count. That will indicate the circuit in which a problem was found. Once I have that information I should be able to give you the probable cause and remedy.

    The 4 blinks usually indicate the loss of vertical deflection. If you can solder and are comfortable wrking inside the set (realize that there are potentially dangerous high voltages present even when unplugged), you can fix this yourself.

    Look for a small flat IC attached to a heatsink that is marked TDA8172. That is the vertical IC. Try resoldering the pins first. If that fails to resolve the problem, replace the IC.

    Let me know the results as there may be other components in the circuit that need to be changed as well. If that is the case, the symptoms should change.

    Keep me posted,

I have a sony trinitron 27 in. model KV-27S45 1998 it will not turn on and the stand by timer is flasing 4 times dont know what to do

Vertical IC inside your Sony TV has damaged [shorted]. Four blinks of standby light denotes it. The number of blinks of standbylight in Sony denotes some fault, and can be determine according the the continueous blinks. In your case, the standby light will blink four times, then stop for a while and will continue to blink four times and so on. Vertical output IC should be replaced with same type and number. If you are aware in electronics and have tools, you yourself can do the work.

Sony Trinitron Color TV KV-35V65 - No Picture, red light stand/by timer flashing

A reset won't fix this. The standby light should be blinking a repeated count with a 3 second pause inbetween. Post that count here. That will indicate the circuit/condition that is preventing the set from turning on.

Sony kv-35s42 no picture, good sound timer light flashing

Usually, the CRT is is a temporary fix at best........try adjusting screen control on CRT socket module.

Only other possibility is solder pins of vertical output IC.
