Sony TV Error Code - Four blinks.

You try to turn on your Sony TV and nothing happens. Then you notice that the standby light is blinking. Counting determines that it is four blinks about a second apart followed by about a three second pause. Perhaps you see a thin white line in the middle and across the screen.

Your problem is that you have no vertical deflection. Check IC1509, Q1505. These are on the deflection board. If you are not familiar with replacing discrete components look at my tip at http://www.fixya.com/support/r4751428-fix_no_vertica_drive_problem for more help. If you cannot solve the problem using my tip you may just want to purchase a new board.

Fortunately these days circuit boards are not that expensive. I would recommend replacing the defective board. The board with all the power supplies in a Sony is generally the "A" board and contains the High Voltage power supply. This is also where the vertical IC is located. You can determine which board you need by following the four wires from the yoke (coil on the neck of the CRT) to the board where they are plugged into. This is the board containing the vertical IC.

Two of the best places to get the board are http://www.encompass.com or http://www.shopjimmy.com . Prices are similar but both sites are trustworthy and will allow you to return the boards if they are not the problem.

If you haven't replaced a circuit board I have a tip at http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs which explains the process and should be helpful to complete the repair.

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.http://electronicshelponline.blogspot.com/

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.
