It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

You probably just lost components in your power supply. A repair like this is generally 175-225 dollars.

  1. Did you try to call LG/Zenith customer support and see if they can help you? If not find your nearest LG/Zenith service center (not Best Buy) preferably a small service shop to see if they have a service remote to unlock it

if it comes to a replace ment board that is a fair price. matter of fact if you purchase the board over the web rather than a electronics supply shop locally you are wasy ahead of the curve. my advice is however if you have to ask how to replace the board you should not attempt the replacement your self. you should always be safe when working with electronics wether they be plugged in or not. often times even unplugged the unit wil;l still store a charge in it's capacitors. also if not careful static shock can damage other componants in the unit. find a friend to help you or take to a good repair shop.

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? 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.

No, the Zenith XBV443 can not record a VHS tape to DVD. This unit is a DVD Player/VCR recorder. It doesn't have the ability to burn data/files to disc. The manual is available at ManualsLib: https://www.manualslib.com/manual/267291/Zenith-Xbv-443.html . The DVDs that it can play are limited: https://www.manualslib.com/manual/267291/Zenith-Xbv-443.html?page=5#manual .

I wish that I had better news for you.
