Re: 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 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? Comment posted on Apr 22, 2009 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? Comment posted on Apr 23, 2009 Purchased 2 and half years ago. Expired one year warranty. Comment posted on Apr 23, 2009 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. Comment posted on May 14, 2009 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.

In my 42" HDTV Plasama TV I heard a loud pop.

You will find that the power supply has failed and is no longer supplying the VS voltage that the screen requires to produce a picture.
Call a specialised engineer that is authorised to work on your make ot TV.

Pop sound then no picture, just sound

I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

No picture but has sound

The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up.
The TV must be taken apart and tested before eventually replacing sustain boards.
