Re: Problem with Samsung ps43d490 PDP

I do not know for sure, but I think it applies to all D4x sets, i.e. D440, D450, and D490 (3D).

Hi tom66. The panels have arrived today and i finished with the replacement. First i replaced only the YSUS and indeed, the problem was the YSUS, because after the replacement it was ok. I turned off and replaced the X-main too, but when i try to upgrade the fw says that couldn't find fw files on the usb. The 1029 ver. it is on the TV and i try to refresh it, but as i see he supports only newer fw, the same fw on the usb is not ok as it's not a fresh one... Should i downgrade to an earlier version and after that upgrade again to 1029, or it is not necessary? It works great the TV, it is alive again and nothing has changed, beautiful colors and no problems with the display.

Is your TV currently running 1029 or a later version? If it is, then do not update it.

Hi, and sorry if I go to this discussion.
on the following PS43D450A2W TV, the following tabs are corrupted:
Y-SUS BOARD LJ41-09479A R1.7 LJ92-01797A
X-SUS Board LJ41-09478A / LJ92-01796A Rev.1.6
Both have a lot of shortcuts, I'm trying to fix the cards.
on the X-SUS board I can not identify a short component, it is a zener serigraphic ZD 4010.
Can anyone post the features of the zener?
On the net I could not get the electrical layout of the frame F82A.
Thank you .
