First off I want to thank everyone in this thread: http://www.techlore.com/forum/thread/19333/Sony-Bravia-KLV-40U100M-Turns-off-and-then-back-on-while-watching-program/
A friend gave me this nonworking piece of ---- yesterday and I promptly tore into it. I’m a Panny guy and never had problems other than bulb replacement. So, I find the “B” or G2 Board at NR901, Current Limiter INRSH 5 OHM 20% was blown to bits and had left a nice BIG hole in the backside of the board. I spent most of the day searching the web for info, found this forum and the extremely helpful thread referenced above and was able to sort out the mess. I think I read through all 217 posts, but didn’t find this answer…
For those of you facing a no power board have a look at NR901 and if it’s blown here’s where to get the piece: digikey dot com , part # 495-4113-ND . $4.59 for one plus a couple of bucks for postage. It beats the $380 I found for the whole board.
I also checked the condition of the U24 IC on the "A" board and it looks like mine was replaced with a K78W. Kewl! we’ll see if it works and stays on when I get this thing running.

what is the sku of the board I bet ptscorp.com has the entire board for cheap. http://www.moduslinkptstvboards.com/LCD-Boards-C12.aspx?s=Manufacturer ASC&p=176
oops copy and paste the entire link it seems to have only highlighted half of it
Received the current limiter in the mail today, it's about 4 times bigger than what was there, soldered it in, annnddd it works! Best 6 1/2 bucks I've spent in a while.
Thanks again guys and gals.
