    Yes... The fan comes on when I power it up. The green power light flashes 102 times then lights solid green. The display however stays black. I can't even get the WEGA menu to come up.

    Thank you...

    Do you hear any fans turning when you turn it on.

    Did either of the suggested solutions work for you? I think I have the same issue. Thanks

You either have a Ballast that is not firing the Lamp or you have a communication issue that is not telling the ballast to fire. You can confirm this by opening the lamp compartment and removing the lamp. Turn the set on and see if you are getting a blinking red led that flashes a error code. If you have this then you probably have a bad ballast.
If you don't have a error code flashing you probably have a bad Q-Box. It is a common source for communication issues. You can order it by part# A-1110-067-A through Sony via 1-800-222-Sony if needed. I'm sorry I do no have the part# for the ballast. Retail cost
is 471.50
Well, that is all I could come up with.
Hope it helps,

While tv is on, at times screen just blacks out ...then comes on again.....audio remains but picture fades in and out....often


Replace lamp in tv because symptom shows lamp is near to end of its working hours life and causing that problem.
If lamp has not been replaced in tv in last 2-3 years, its time to replace it to solve the issue.
Lamp replacement procedure is easy and written in user manual.
Thanks.

If this is a KDF-E60A20, most likely you have a bad Lamp. It is a common symptom.
