    This is a fan problem. One or more of the fans is probably not spinning.

Some of the fans are encased in areas you can't see. If you have a meter and want to determine which fan is in failure, you can find the small 3 wire fan connectors and measure the voltages on the wires.

Black wire - Ground
Red wire - 12v
White wire - 5v (RPM wire)

Zero (0) volts on the RPM wire means the fan isn't rotating. You will only have about 10 seconds or so to check the fans, so measure quickly and turn the TV back on to measure the ones you missed when it shuts down. Even a rotating fan can have a bad RPM sensor internally to the fan.

NOTE - these fans operate the same way they do in computers, providing rotation RPM to the motherboard for monitoring.

You are correct that a 4 flash is a fan problem. It could be that one or more of the fans is not turning, I have also seen a failure of the fan rotation sensor that tells the TV that fans are turning cause this problem. Lastly, in rare cases a power supply problem can cause a 4x failure, when the supply for the fans fails.

Kdfe55a20 won't turn on at all It's a Sony


which LED lights on front are on and or blinking?

If the red or others blink look to see if they are blinking a specific number of times--like red one blinking 3 times, pause and repeating--this is a error code and may indicate what problem in set is.

Got a new lamp tv works great but wen I turn it off it has a very quiet hum is this normal also wen I turn it off the.red.light blonks green for a while befor eventualy going away what dose this mean...


Hello; The noise when turning set off is likely the fan that cools the lamp down gradually. The lamp can crack if the fan does not work. Dust in the fan can also add to the noise. When the set is turned on, the microcomputer watches the lamp come up to full brightness and shows this with the LED colors. All lamps containing mercury take time to get up to full brightness.This also applies to mercury compact florescent lamps, yard lights, and even neon signs that contain mercury.

Tele turned itself off, red light blinks 4 times then pauses and blinks 4 times again.


You can try unplugging it for a while and then plugging it back in, but according to the manual, the standby LED:
Lights up red when your TV is in PC power saving mode. If the LED blinks in red continuously, this may indicate the TV needs servicing.

Hi,
Red led blinks 4 times is an error code that shows that fan is not running in tv, check fans connections and make sure all are plugged properly.
Thanks.

Power LED blinks red


it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
