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.

Sony tv red light blink 4 times on 60" WEGA


When your red light blinks four times on the Sony KDS-R60XBR1 60 inch HDTV, this is an error code for a stopped up fan. You will need to check the ASU board to verify Fan1-4 power to the fan is supplied, next check the fan connector to make sure it is properly connected, and finally make sure the fan is not caught in the wires or harness.

What does it mean when red light blinks 4 times on sony sxrd tv


The service manual lists 4 blinks as "Fan Stopped". Probable cause is - "Fan 1-4 power is not supplied. (AGU board) - "Fan connector is not attached securely." - :Fan caught wires or harnesses.
I had this problem recently and I was able to clean it up and get it running again.

I have KDS-50A2000 Sony SXRD Projection TV. Serial #9028985. It was working fine then a few days ago I went to turn it on and the red power light was blinking 4 times and repeat... I then opened the lamp...


hello, this can cause the red power light to flash 3 time also if the lamp cover is not fitted securely this can also cause the light to flash 3 times 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 hope it helps

Power light flashed red 4 times then repeats no pic,new bulb/fan!


Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.
