I heard a loud pop then tv screen went black, now

time to take it in for a proper diasgnosis and then to decide if to fix or not

Hi,
Is is standby light blinking red or any other light? Let me know how many times red standby light blinking after three seconds long pause to provide you helpful info.
It seems pop sound was due to broken lamp, please check lamp inside tv and if it is broken, replace it to solve tv problem.
Hope this will help.
Thanks.

Ur tv power supply board is dead.Replaced the power supply board,ur tv power will return,and the tv will work again.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

bad lamp

same problem, red blinking light in series of 5 flashes

When my lamp died the bulb literally exploded. That may be what you heard. Have you check the lamp? If the lamp is ok, the lamp's ballast or power supply might have blown.

Sounds like the Power supply module. I would take it in to service center ASAP!

is there any led or small lights on front panel ... red green or flashing

sounds like the lamp has shattered. check the lamp

Does anything come on the screen? Input display box? 
If no:
Sounds like it could be a blow capacitor. Cheap part, but need someone with a little electronic know how repair to fix it.
