Hello
In Sony TVs, number of blinks of the standby light denotes some problems inside the circuit board of that TV. The number differes with the section where the fault is. According to the number of blinks, we can reach to fault point easly. Just count the number of blinks, with TV switch On-Off with its front panel switch, not by the remote control. Keep this in mind. Ok.

The 4 blinks usually mean a vertical deflection problem. If you can solder you should be able to repair this yourself. Let me know if you wish to attempt the repair and I'll provide more details and instructions.

Hello,
There are 3 reasons for 4 blinls
1.unit went to stand by mode because of h-pulse
2.Vertical defflection pulse stopped
3. power line is shhorted or power supply is stoped.

Solution:
1. check 13vdc on A board of powersupply stage
2. Check IC561 on A-board.

Good Luck

The blinking red light at the the front of the television is the "Diagnostic STANDBY/TIMER LED".
This little red light will blink 2, 4, or 5 times and then stay off for three-seconds. And blink again for 2, 4, or 5 times. This cycle repeats. The most common diagnostic code is the 4-blink code.

When the red LED blinks 4-times, it means one of two possible causes:
1) +13V is not supplied on the A-board. Or, 2) IC502 is faulty.

It is best to take this television set to a repair facility and ask that the +13V power supply be repaired.
The copper tracks and integrated circuit pads are very thin and delicate on the KV-24FV12 circuit board, and will easily lift off of the circuit board, if the incorrect desoldering tool is used. Unless one has a good quality PACE vacuum desoldering unit, one should not attempt to repair the television.

Sony KP53HS10 5 blinks
Five blinks means "Video out abnormality detection". Possible problem areas are as follows:

Video out, IC7101, 7201, 7301 and others in C board circuit.
Q510, 516, 524 (A board).

There are actually three C boards, the CR, CG and CB boards. They are attached to the rear of the red, green and blue CRTs, respectively. I wouldnt attempt to repair the set myself. I would solicite the services of an authorized Sony servicenter.

Definitely bad picture tube==not worth fixing......T.

Due to playstation or dvd nothing will happen. 5 red flashes means jungle ic failure shows this display. Technical person only sorted out the above problem.
