What does it mean when the standby light flashes four times on a Sony TV Model # KV-24FV12 ?

These blinks [flashes] are fault indication (Error Codes).From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it.This will make repair easy.These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times.Count it carefully.If you wish to get some details, check the site linked here.It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
Blinking codes details to many popular brand TVs are given.Surf the site with patience.

I cant get sony trinitron to turn on. the standby/timer red light blinks several times and it wont turn on what can i do i am bored without tv

Likely damage to main power supply-------try to see if there is a specific number of blinks then a pause and repeats like 7 blinks a pause and repeats---that is an error code if there---with it AND THE MODEL NUMBER OF THE TV I might be able or not to help.

I have a Sony SRS BBE Trinitron (WEGA). The last few days when I tried to turn it on using the remote the Red Light would go on but the TV did not turn on. I would have to press the power button again to turn it on.. I tought the remote battery was just low.

Today when I tried to turn it on nothing is happening and the Red Light is blinking 9 times ??? I tried to unplug it and try it again, still does the same thing ???

We need help...

Sometimes tv won't turn on and standby light blinks and sometimes it works perfect

The key here is the number of blinks of the standby light. This is an internal diagnostic code. Please provvide that count and I should be able to suggest possible fixes.

Blinking Standby Light

KV32hs500 tv won't turn on. Standby light blinks 7 times, stops and then 7 more times, etc.. The tv will usually come on after about 2 hours or so of being off. Plays fine when on but once it gets turned off the problem happens again. Any suggestions? T.V. is 5 years old.
I have a similar problem . mine blinks 6 times or 7 sometimes also,and comes on with sound ,no picture for about 2 seconds then shuts off. Anything?

No Power

The first thing to check is the horizontal output transistor,it might have shorted out and opened the fuse or safety resistor that gives him power to operate,sometimes it goes bad by itself and sometimes the output transformer goes bad and takes him out too.If you are familiar with tv service you have a place to check but if you are not to familiar be safe and seek the help of a servicer.Let Us know how it goes or if you need more information.
