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.

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.
If you wants anymore assistance, feel free to get me by Fixya.
Thanks for using Fixya.

TV SONY KV-HA21M80 BG2T

Thanks for reply and nice to know that you are in Algeria.

You need to pay attention on Screen Volts as wrong G2 (screen volts) can be cause of 4 times blinks as you already replaced vertical out put IC.

You can download service manual of KV-HA21M80 from HERE and it is free. Download all 3 parts of file and use WinRaR to unzip it. You will have complete manual in pdf format.

Good luck.
