It could be in the horizontal output circuits causing the power supply to shut down in a protect mode. Technician: Tim Rasch

Most likely the main power supply is defective.

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

Replaced bulb yesterday worked fine. Today light will not turn on. projector turns on both lights green for 10 seconds, then power goes red and status blinks green for about 5 seconds, then status light...

green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
