Hi Guys
I just wanted to contribute to this great forum.
I recently repaired a Samsung Plasma TV
Model # PN50B450B1D
Model Code PN50B450B1DXZA

With a simple replacement of these components
Part was a RJH3044

I actually replaced all 4 simply because I had them.

I saw a video where these models often have these components go bad.
On a hope, I ordered 5 of these for $3.50 or so for all 5
Good thing I got 5, because I broke one of the legs on the 4th one.

Any way here is where I got them ...

Re: Strange Delta DPS-222BP power supply behavior

Hi guys.
Just got a dead LC-70632U. I ordered a replacement Power board (Is that known as the PWB? Seems likely) Anyway, I love this thread and suspect I may be adding a little when I get further along. The unit flashed 3 long and 1 short. No other indications. Strangely when I first brought it home, it powered on and showed a screen when powered on in my truck bed. When I brought the heavy son of a gun in and put in place it was dead as indicated above. That of course made me suspect a solder/run problem, but initial inspections...
