By 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. http://electronicshelponline.blogspot.com/

When i try to turn on my sony kv-27fs12 keep turn off and blink 4 time a red led make a pause and keep blinking 4 times, what that could be?


Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
Vertical sweep failure. Check all the solder terminals to vertical output IC. If it do not help, replace that IC.

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.

Sony kv 35s42 sound but black screen and constantly blinking stand by/timer red light


Your vertical IC will need resoldering. If you can take this board out and inspect the pins under the vertical IC, you will see rings around the IC. This is a common problem for you model of TV. Hope this helps...show a few hands of support.

Its blinking 4 times then solid then 4 blinks etc there is no picture can you help


4 blinks means vertical section is faulty. check the supply of vertical ic +/- 15 volts if present. if these voltages are present, re-solder or replace vertical ic.If not, check for faulty fusible resistors and rectifier diode near fly-back transformer.

Kv-32fs16, no picture or sound , red lights flash 4 times


Hi
In sony tv`s the 4 blink code(sony error codes)usually means that there is a vertical deflection problem.
It is often caused by a faulty vertical output i.c and/or related components. If you feel handy with a soldering iron let me know and i`ll help you with it.
Hope this help Merry Christmas

error code 4 is vertical deflecton failure . replace the vertical deflection ic. and the electrolytic capacitors in the vertical circuit. Or if you are lucky just resolder the vetical IC and resolder th horizontal section too.
