LG 50PS8000 zsus board and possible plasma panel problem

[Kenman]

Hi everyone,

I'm currently in a little dilemma with my LG 50PS8000 plasma.

I have identified the problem is with my zsus board. I replace it with a used board and it worked perfectly for 2 weeks then failed. The part was under warranty and I am getting a refund which was good.

I spoke to the guy at the shop who told me the plasma panel causes the zsus board to fail. He said something to do with the increasing resistance in the panel, through usage, causes the problem with neighbour circuit boards. Can anyone shed some light on that matter?

So if the panel is causing the problem then there is no point of repair/replace the zsus board as the panel will just damaging the circuit boards. On the other hand, if the panel is not the issue then it could just be the used zsus board I got was on its last leg. Now, the question would be is it better to buy a brand new circuit board £110+ or get my faulty board repaired £60?

Any help will be appreciated.

Ken

This is mostly untrue for these LG panels. It is extremely rare for it to occur. Whilst it's possible, it's much more likely the part simply failed (it is a used part, so it's already had many hours driven out of it.)

Thanks for the reply Tom, much appreciated.

Any advice on whether I should just get a brand new board or get the board repaired? the price difference is almost half which makes me think it might worth just repair it.

Brand new, as in from LG direct?

I was asking if the actual part was from LG directly...

How many hours on it?

I have an old LG, and that has 17,500 hours on it, and counting.....!

Personally, I doubt that increased life/panel-resistance will kill the Z-SUS--IF that was the case, then a universal test we use to determine faulty buffers--by disconnecting them--and the panel, would kill the Y/Z-sus....

@Tom - Sorry... No, I brought the part from 'flattvparts' near where I am. I did call LG before I read your reply but they do sell the board anymore.

@Alastair - The TV only had about 18 months of usage but I had it since 2009, so approx. 4000hrs. I assumed the zsus buffer board was ok because when I replace the zsus with a used part, the TV was working as normal until it broke again.

If you bought it from FlatTVParts it is a reclaimed part, from a broken TV. Nothing wrong with that, but it's not a new one.

Ok, I will try my luck with a brand new and see how it goes.
