Easy Common Fix for Sony TVs KDL Red light blinking

The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.

Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.

basic sony reset below

The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.

1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
   
2. Unplug the television power cord from the electrical outlet.
3. Let the television remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
   
5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center

Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

The 4 blinks do not actually mean that your lamp is defective, but rather that something is wrong with the TV's A-board. Specifically, 4 blinks means no vertical deflection (V STOP), which screen goes to a single horizontal line then the video signal muted. My recommendation to fixing this problem would be to call Sony and ask for repairs, and you can contact them at:
800-222-7669 Mon-Fri 8:00AM-12:00AM
Sat-Sun 9:00AM-8:00PM EST
If you want to get a hold of a customer Rep quickly, you can try pressing the 0 key on your phone about 3 times.

Never a good sign when you have red flashing codes

4 times, Diagnosis: Vertical deflection stopped. Possible causes: +- 15V is not supplied. (D board), IC8003 is faulty. (A board) Symptoms of the problem: TV has entered standby state after horizontal raster, Vertical deflection pulse is stopped, Power line is shorted or power supply is stopped.


Please rate my help++++Thanks for using FIXYA

6 times red light blink shows error in power supply (GT) board because of no 12 volts output for some reason.
Replace GT board to fix the problem.
Let me know if you need GT board part number info.
Thanks.
