Thanks for the info, working on it and get back with you in 5 minutes.

Expert:  Shahid replied 2 months ago.

There are three lights on TV, top one is labeled as Timer, below is Lamp and last light is Temp.

Can you please recheck what light is flashing?

Expert:  Shahid replied 2 months ago.

If top light (timer) is flashing when turn On the TV then give it few minutes until it stop and check what lights are flashing now on TV?

Customer: replied 2 months ago.
Timer is the only light that flashes
Expert:  Shahid replied 2 months ago.

OK, got it. that flashing light is indicating that lamp is being turned On/ TV is booting up. If this process takes longer time that means lamp has been reached at end of working lifespan but not broken yet (almost dead) and causing the problem as TV tries to fire it up but it doesn't not so timer light keeps flashing.

At this point you would need to replace the lamp in TV as new lamp will fire up in time to bring the picture on screen. Required lamp is available at following Samsung Parts link for $119..

Please do not buy a cheap or fake lamp that would be available all over internet on low price like $20, 40 etc. Lamp replacement procedure is written in details in TV user manual, click following link to download copy of manual if required..
