Hi everyone, I think I know the answer to this, and it’s an easy one, so here goes. I acquired a Hyundai HPT-4240 Plasma TV from an insurance write-off when the classic black strips occurred, and I fixed these previously with no problems. However, I now have the other popular problem with this set, bad 1uF caps on the PSU (DGK-420w) causing it to fail.

However - in the process of inspecting the TV for problems I noticed some large capacitors had swelled up on another circuit board to the left of the PSU board.

I believe this board powers the plasma rather than being part of the PSU itself, as it has ribbon cables running directly into the panel. The caps that have failed don’t like the usual low-ESR caps that normally go – but are large power caps. They are noticeable in particular as there are a pair of identical caps on a sub-board of this one that are not swelled at all. Should I replace these caps as well?? I’m wondering that a fault with the caps on this board may have stressed the PSU and caused the initial components to fail. Ive included photos of the good caps and the bad below – any comments much appreciated Thanks! Driver Impressora Hp Laserjet P1102.

To be 100% sure, try pushing down on center & you'll notice it is not that actual case---just a plastic cover that has bowed g0rak Joined: 19 Mar 2008 Posts: 6 Location: Brighton, England Posted: Thu Mar 20, 2008 7:55 pm Post subject: Thanks for your reply vtech. I have to say you have to press relatively hard on the top of the capacitor for the plastic to push inwards, but this could be thick plastic. The other cap with the rippled top moves even less, if at all when pushed.
