KDF42WE655, i have replaced the lamp about a year ago, the TV is about 8 + years old

Thanks Vincent for the reply.

Do you remember where from the replacement lamp was bought and its price?

Customer: replied 4 years ago.

Direct from Sony, about 250 +

ah OK, do you still have lamp purchase receipt to ask Sony about lamp warranty?

Please unplug TV power cord from wall outlet for 10 minutes to reset, replug and check.
If problem doesn't solve then I'm sorry for no good news, lamp in TV is about to fail or can say lamp has reached at end of working hours lifespan and causing this problem in TV, need lamp replacement to resolve the problem.
Please note that lamp is not dead / broke yet but its performance is weak and protection circuit in TV sense it and turn it Off and back On in attempt to correct this issue, its like protection circuit is confused by lamp performance and it happens when lamp got weak or about to die.
I wish I had better news or easy fix to resolve this problem.

I trust my input will help you out. Please feel free to respond if you have any additional questions.

A positive rating to answer would be greatly appreciated!
