TV won't turn on. Green light blinks for a few minutes, then goes to red. There is a high pitched noise when green light is blinking.

If it EVER works, then the problem is not a failed part, but a weak part. The most likely component type to give you such problems are capacitors. But very few repair techs know how to find such problems, and even fewer have the equipment needed to find the bad one(s) in-circuit. The failure mode is high ESR (ESR means Equivalent Series Resistance). The lower the ESR, the better. Capacitors with high ESR cannot stabilize circuits which demand high pulse currents, such as in switch mode power supplies.

I had AWFUL customer service. (Sherry is DREADFUL her # is 1-877-543-8325 she is in"executive services". Ask to speak to her directly...if you would like ZERO help.)

They WILL NOT extend the warranty, even though they know there is a defect with this AND other models. Zenith name on the front...LG guts in the inside.
Ours turns on, screen black and then clicks three times and then turns back off.

My TV surname off after 5-15 minutes of use. The red light in the front blinks once every 3 seconds continuously. If I hold the power button down on the tv, it will turn on and do the same thing.

power light if it shuts down should blink a error code--count the blinks and a pause?

sounds like the projection bulb went bad. change the bulb and it should work. sometimes they make a high pitch noise when they are trying to turn on. the bulbs seem to last about 2 years for me.

Hi, Symptom shows high pitch sound is of color wheel that is not spinning any more so TV stay in protection mode and does not power up. TV requires color wheel replacement.

Check the lamp door (with green on) ,.. both green and red blink - bad lamp. Green off, red blinks..Try unpluging for 2 minutes and retry - if no different (sorry, call a service person).

I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.

the tv will try to reboot a few times. just let i try and eventually it will start blinking red. if you could count the red blinks then i can further assist you.
