The picture dims fors few seconds and the returns to normal bightness. This happens occasionally. Was first noticed while watching a show recorded on DVR. Seems to happen after the TV has been running for over 1 hour. Not sure if the lamp is ready to go out or could be something else. The LED indicator lights on the front on set blink as if everything is normal when the set is turned on or when switched off.
It is possible that the TV image backlighting is failing.
The buzzing sound you most likely hear is the ballast trying to fire up the lamp. I would say replace the lamp and yes they can act up at will. If this is the first lamp replacement ever then you are doing good.

Yes, they dim as they age, and you've done well to get 3 years out of one.
Projection TV makers charge an arm and a leg for their replacement
lamps. They make it easy to do but as a result the custom lamp
assy is expensive. The trick is to just buy the bulb for your
model TV from any number of us aftermarket sources at a fraction of the
lamp price and install it in the old lamp yourself. really
easy.

Thank you so much for your help.
I own a 1998 Hitachi model no. 60EX38B serial no. V8E001713
As I was watching the TV the picture and sound went out.
The next day I turned it on and after an hour it went out again and has not come on since.
I have no video or sound. Would you be so kind and explain what could possibly the problem before I go to the exspence of any costly repairs with the TV being it's age.
Eagerly await your reply
Thank you for all your help

It is likely the projection lamp is weak, causing the picture to cycle on and off. Take the lamp out and examine the reflector. If it is dull and cloudy, it's time to replace the lamp. A new lamp will have a reflector that is shiny and looks like a mirror. Be sure to rate this solution. Thanks!
