This is usually due to the power supply going in to the protect mode, and failures in the scan amplifier and or the CRT drive sections. It is not a simple repair.

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


Hello
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.

My tv will not turn on


The blinking standby light is an indicator that an internal safety circuit has kicked in. The light shouldbe blinking a repeated pattern of count/pause/count etc. Can you please post the count here? That will indicate the problem circuit and allow us to provide you with the solution.

Thanks,

A frinds's grandson turned on the delay timer on her set. now she can't turn it on. how can she override it? She has trien the remote control and the manual buttons. She has unpluged it for up to 15 min....


Its not a problem ith any timer . That tv has no lock able to keep it from turning on. The tv is broken and the stby light is blinking a pattern indicating an error code. Probably six or seven blinks in a row maybe four. My guess is that it needs two regulator OSC I.C.s and a capacitor replaced. I think you should take it to a sony authorized servicer. Its a good model , worth repairing for no more than $250.00 or a little more if they'll pick it up and deliver it.

Standby light stays on and the tv will not go on


Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem.
You question shows standby light stays On that means TV does not receive power on command from remote.
If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution.
Thanks.

Standby light stays on


When attempting to turn on the set, the standby light should blink for a a while then stop once the picture comes on. If a problem is detected internally, the standby light should blink in a repeated pattern. Please count the number of blinks that are repeating and we should be able to help.

Sony kv35s26 TV: no picture, audio works, stanby light blinks.


First a couple of questions:

1) Does the standby light blink continuously or is there a repeating pattern?

2) If there is a pattern, can you please post the blink count?

With the above information, I should be able to provide you with a couple of possibilities as well as a few tests to perform. Please update this and we'll continue to try and resolve this.

Thanks,
Dan
