Re: RCA L42WD22 No Picture

Well, if I could see the part numbers clearly on those transistors, I would've just ordered those for a dollar a piece from newark. But would not know the actual part number for that surface mount fuse, but would've found something. From my searching, shop jimmy had the best price for the slave board. About 60 dollars with shipping.

Re: RCA L42WD22 No Picture

Got the slave board from ShopJimmy today, popped it in and all is good. LCD backlight is now firing up and TV is at 100%. Your readings from the ballast transformers were the same as mine from the primary and secondary. 16ohms and 1ohms.

Good Luck!

Re: RCA L42WD22 No Picture

Same exact problems with the same tv I'm currently working on. The 2 bloated caps on the master inverter board. Replaced those. Transformers look/test good on both boards. Then I jumped over to the slave board and, unlike the master, 25 volts was not going past that smd fuse. So something must have popped it. Found the same 2 smd transistors shorted. Nothing else though.

I just bought a slave replacement from shopjimmy.com, couldn't find the transistors online due to error in reading make/part number of the transistors. Now that you've posted...
