Do you see any pattern to the flashing ? How many times does the yellow and then the red blink?

Customer: replied 1 year ago.
The light stays green for a few minutes blinks yellow a few times then turns red.

Is this the bulb?
Expert:  Nathan replied 1 year ago.

No this is not a lamp issue.

There is an internal circuit failure. I'm trying to get a specific pattern from you to give you a better idea of the problem.

Expert:  Nathan replied 1 year ago.

Unplug power to the tv for 10 seconds, then plug back in, and watch the light carefully. Count how many red flashes, then how many yellow. It will pause, then repeat the pattern.
For example it may blink 3 times then 2 times, meaning a "32" code.

When I plugged the tv in the light blinked green 122 times, When I pushed the on button the light came on green but the tv did not come on.

Now the light has turned red. There is sound now but no picture,
Expert:  Nathan replied 1 year ago.

Again though it should be flashing in a specific pattern. a certain number of red, then yellow, pause, repeat.

Are you not seeing anything like that?

Can you hold the power button down for 10 seconds to reboot, then watch again

Green blinked 3 yellow blinked 5
Expert:  Nathan replied 1 year ago.

Are you sure it was green then yellow? It should be red then yellow.,

Expert:  Nathan replied 1 year ago.

None of the indications you are seeing at this point are consistent with any specific error, it is just random behavior.

Unplug power for a few minutes, plug in, press and hold power button 10 seconds.

Watch the lights again carefully. We're looking for a pattern of red blinks then yellow blinks.
