KDF 50E2000 WONT POWER UP POWER LITE BLINKS RED 3 TIMES THANKS


Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.

If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

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.

If the issue continues to occur, service may be required.


Thanks for using Fixya.

Tv will shut off and red light will flash 3 times


If its Sony KDF-42WE655 TV that goes to standby and LED blinks 3 times then check Lamp Door that seems not fixed properly.
That happens when lamp replaced in TV.
If its different model number TV, let me know exact model number.

Pioneer Elite PRO-520HD wont stay on


It is most likely just solder connections on your power supply. If the only diag LED that lights is on the supply, then thats usually the case. You can unplug the set and remove the supply to fix it with a little soldering. You have to remove the metal board supporter from the bottom of the board and solder quite a few connections. Look for cracked connections on the power connectors to the rest of the set, and also connections on the main transformer. If you need soldering experience, get a kit at radio shack and build a little project to get some practice.
