Lamp needed replacement. Changed lamp and TV still does not work. No picture or sound, just a buzzing noise. When on button is pushed the TV acts as if it is going to start up but only buzzes and makes a squealing noise. After it tries to start up and doesn't happen, then it sounds like it tries to shut itself off and then tries starting back up again. This continues for a minute or so and then finally does shut itself off showing all three lights again (timer, power, standby/high temp).
Possible bad color wheel... Pull the lamp out & look inside where the lamp sends the light- does the color wheel look defective? If so,replace it. Or, the lamp ballast may be bad.After that,usually replace complete engine.

I have same problem but color wheel looks to be ok, where is the lamp ballast and how can I change it.
Also, where can I get a lamp ballast? What is the part # ?
Any help would be great, Thx. -Darren
We have a 46"Sanyo with the same problem. 6 months ago we
replaced the lamp with a brand new Phillips which is supposed to be the
best and good for 1-2 years. 6 months in, our tv shut down 2
nites ago and this is the exact problem we are having. The tech
guy at the lightbulb place said most likely NOT the bulb and he said
the power supply. I can't believe on a set that is not even 2
years old this Xmas that I have to replace the power supply
already. I am not calling in service yet. What does a defective
color wheel look like? Or is ballast most likely issue to look
at?
some times i shut it off and back on i wiil get picture again
