Replaced bulb but tv won't stay on for more then couple minutes

Have had this Samsung dlp model HL-T5075S for around 8 years replaced bulbs a a few times so when lights on front came on figured that was issue so bought new bulb. Turns out that must not be issue. It will turn on for a couple minutes then screen goes black the bulb will continue to go off an on if you look through the back but no sound or picture. The two small fans I can see are working but no other noise from tv and this has never been a quiet tv. If we push power button it will turn off and then push again and picture will come back up but only for a couple minutes again. Help I love my tv!

Answer this question I have this problem too

Is this a good question?

@acacjn "so when lights on front came on" which lights and what order? This is important since it can be an indication on what error is occuring. Let us know.

all lights blinking is usually an indicator that the lamp may be defective. you did get a proper replacement?

@acacjn start with some basic trouble shooting. Make sure that you have a proper replacement bulb and check the switch on the lamp cover as well as the temp sensor. Here are some instructions to help you with the initial trouble shooting.
