It is likely a capacitor or resistor on internal board. When they short or overheat, they will pop or expand at the scores on top. They look like small colored & varying size cylinders on the board. Depending on which one blew, the entire circuit board would be replaced. You would need to scroll through the particular model numbers of the tv and see about the board. Usually it is one of 3 control boards and honestly the cost of finding a working replacement at a reasonable cost is unlikely. If it were simply a fuse, you would not have any power or sound so it is an issue specific with the video controllers. Usually Master control board. Tvs are relatively inexpensive...youre best to replace it. Thee issue often happens from overheat of the board componants from accumulated dust on vents or even attracted directly into board. In future ensure it is properly vented and vaccuum rear vents to minimize it. Also be sure to use an appropriate surge protector as even minor household power fluctuations can fry equipment. Some even give insurance to replace damaged electronics. Good luck.
Hi Justin
No picture, sound okay
If the indicator on the front of the TV is blinking for one minute, the lamp inside of your TV may need to be changed. Refer to the Power indicator is blinking. You might have tried to turn on the TV during lamp cool-down. Wait a few moments and the picture will be displayed.

The loud pop was a capacitor blowing up or the high voltage transformer blew up. Very common problem.. if its the Transformer be expected to pay 250 or more to have repaired.
SOURCE: Samsung DLPTV bad picture and buzzing sound
You color wheel blew a bearing. You need to replace the color wheel.
SOURCE: TV's on. No Picture...No Sound
Have a problem with Zenith 37 HDTV. Medel number: Z37LZ5D As wathcing TV, along with 'pop' sound, TV went dead. LG service center gave an advice to unplug the power cord and press ON/OFF power switch about 1 min. Then plug power back and turn on the TV. Well, the green light blink for a while and solid green, but still no screen, no audio. Search the Web and someone suggested to replace Power Supply Board which will fix the problem. Again, search the Web and came out with Power Supply Board. LG Electronics/Zenith 'Power Supply Assembl' with $124.95 from PartStore.com. Is it the right solution? Do I have to replace entire Assembly Board? not just replacing some fuse? Any cheaper way to do? If I have to replce PSA board, any suggestion to how?

I have a basic knowledge of electric and electronics, such as rewiring entire house for renovation and assemble entire computer from scratch.
Actually, the TV belongs to my father and the problem that I stated was based on what he told me.
So the question is based on the symptom that I posted, how sure are you that the problem is the Power Supply Board?
Is it good to order PSB?

Zohail,
This is LCD TV.
There is no problem with the wall socket nor current.
I put other appliances on same wall socket and worked.
It has to be internal problem.
As I mentioned on the main post, there was a 'pop' sound while watching and TV went dead.
Turn on remote control, there is blink green light and then green stays on, but no sound, no screen.
Turn off remote control, light turns red.

I fixed the TV.
Orderd power supply board which cost me $136.51 total.
Replacing was simple.
Just removed the rear panel cover then electronic board housing cover.
Took power supply board with all the connector cables and replaced with new one.
Problem was a transformer connector which got burned and blow up the plastic cover.
But no problem with fuse and capacitors.
Thanks all for advises.
