Well presented repair vid. Pleasant to watch and informative. Great work.

At 5:31 is Wheel of Fortune!!

Samwha are not too bad, it's just the WB series which is known to be defective and was discontinued by the manufacturer in 2002 I believe, the problem is, there must be a large quantity of stock out there because they keep turning up in equipment dated post 2002.

Murphy's law is perfect. Nice repair and information.

fixed a lot of rear projection tv back in the day with the same problem. most of the time its the bridge rectifier ..:)

Its usually the mosfet.....always is.....check the supply diodes sometimes on the secondary will cause the mosfet reg trans to short...have done tv repair for 37 yrs....

@zell318 I thought about the auto program, but I didn't want to mess it up for the owner.

looks like a similar problem to my TEAC Plasma's SMPSU, shorted across primary AC. I will look at the 2 diodes that i noticed a funny smell around after she popped during testing.

@chickenofsea This one belongs to a friend of my coworker. Most of my stuff is either found in the trash, given to me broken, or bought off Ebay. In fact, I have 2 more LCD monitors coming in soon that were non-working Ebay items. I just hope the screens aren't cracked by the time they get here.

What does it say on the board, next to the component? It might be the MOV that is used for surge protection.
