Red flashing light
  1. Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Sony kds-60a2000 power light flashes 5 times, no picture
5 flashes - Lamp Driver - (lamp driver faulty)

This is the error code that usually means the ballast (it is the power supply for the lamp) is bad.

Computer shut down and red light flashing five times then three second pause and repeats
According to the troubleshooting guide for this model, the red light flashing five times indicates a problem in the RAM (memory), before the video subsystem is ready. You may just need to open the case and make sure the memory sticks are fully locked in their slots. If you just added new memory, it might not match the required specs.

Blank screen and the power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.)

Cause Pre-video memory error.

Solution
1. Reseat DIMMs. Power on the system.

2. Replace DIMMs one at a time to isolate the faulty module.

3. Replace third-party memory with HP memory.
4. Replace the system board.

MY wega 42inch wont turn on...the little green light flashes like five time as if it where to turn on but never does...and then it turns red and flash six times pauses and then again the red light flashes...
Six blinks indicates a faulty power supply. often caused by open thermistor located at under lamp assembly or beside it. Or a defective regulator on power supply section.. Check the thermistor and replace if found defective.. Or contact the nearest Sony service center at your area.

TV black on light flashes 3 times and pauses before it flashes 3 times again. When I put the TV on it was OK for 2 minutes and then it went black and the red light started flashing. No sound or picture.
This is probably an error code .this is to help service personnel to find the fault.

Sony Wega
Please count light flashing again. Light flash time is "0.3 Sec" and there would be pause (light Off time) for "3 Sec". Start counting after pause to next pause.
