Hello and thank you for the question.

How long have you had the set for and when did the problem occur?

Also, are there any blinking lights on the set?

Customer reply replied 4 years ago

About 9 years.


Just started acting up last week.


no blinking lights.

Thank you for the reply Robert.



When was the last time that you replaced the lamp on this set, and where was the lamp purchased from?
Ask Your Own TV Question
Customer reply replied 4 years ago

Never changed the lamp.

Thank you. Robert, the original lamp in the set is only designed to last trouble free for between 3-5 years tops under normal use, and a weak lamp (which this one undoubtedly is), will heat up and cause the symptoms you are having. You have to let the set cool for 40 minutes before you power it back up as well which is common with this problem as well. You really need to change the lamp at this stage as it is very tired and can damage the TV if you keep attempting to operate the TV this way.

The link below is where you can purchase the correct OEM (not a lesser priced sub), Lamp for your set to cure this problem:

Good morning,
I changed the bulb for an original as you suggested.
The picture is definately nicer but same original problem persists.
Set was off for about 3 hours yesturday. Fan was still running & I could not get a picture.
Sound came on & set turned itself off, tried to restart itself twice & stopped.
All 3 ligts were flashing, timer, lamp, temp.
Had to unplug. Was able to turn on normally about 15 minutes later.
Any other suggestions?
Robert

Robert if you have the same problem with a new Lamp and the three blinking lights, then you either have a faulty Ballast or a fault in the Power Supply. Do you have a meter and are you comfortable measuring high voltage DC off the ballast, or to the ballast?

I am not that at ease but shall check with son-in-law.

Okay that sounds good. For all intents and purposes the blinking on the set points to the lamp, but beyond that other components that fire the lamp are suspect. Let me know when you know if your son in law is available to do some testing in the set.

Is there more than one fan on this model?

Yes there's three fans- the DMD, Lamp and exhaust.
