Samsung 42u2p y main transistors???

[DukeCuevas]

Hi all, Ive been searching through this incredible site but I cant seem to find the answer to my problem... i have a PN42C450B1DXZA plasma tv, I found shorts on both the x and y main, my problem is i removed the shorted fets from the heat sink of the y main thinking they were all the same (I know super rookie mistake) and now I'm not sure what goes where, i realized this before i repaired my x main so I didn't repeat the mistake there but i was wondering if anyone maybe had a picture or maybe a list of the transistors? Anything would be a great help!

Hi there sorry for the late reply, I'm lost on the y main, I pulled all what I believe are the mosfets on that board, it's a Samsung pn42c450b1d.. tia!!

The Y Main was my issue. although buffer board did not read any shorts, I replaced both the Y main and buffer. Whatever is shorted on it was shorting 2 of the IGBTs on the X Main. Working like a champ after firmware upgrade.

That’s awesome! I got mine to fire up but I shorted the igbts again, by chance were you able to see the parts I mentioned? I can’t for the life of me remember where they go! I’m just getting started in this hobby and I got 2 lcds back to life but this plasma is a pain in my neck!!

I love plasmas for the quality they deliver.

K10A60D is farthest to right

That should get you there.

Q5008 is the only one that shows to be shorted on my board.
