Sony kdf50e2000 will not stay on red light blinks 4 times

Does the front light stays green ? Or goes back to red ? The back-light going on/off maybe the problem, but it shoul return with a red blinking led (4 times ?) and if so it can be a power inverter problem.

The set should if shuts down have the power light blink a specific code or number of blinks-----3 blinks?

the lamp door cover is not secured properly or the lamp is not inserted correctly. Thats what the 3 blinks is indicating.

call Sony tech support

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.

Your lamp door switch or lamp switch (there are 2) may not be fully engaged or one may have failed. Try seating the lamp again, you may not have it fully installed.

Please intimate exact model of your Sony TV and also mention how many times red light blinks as there would be pause of 3 seconds in blinks so count pause to pause and let me know to find out problem.
How old is this TV and did you replaced its lamp?
