Re: Samsung Plasma PN50C550G1F : no image, but sound is ok

I have replace the connectors.
The bottom section is now fine.
The top still have some lines.
When I play with it they "disapear" (lines are displayed properly).
The top connector is a bit loose and I can't get a good connection now.
Any ways to secure it?

The top connector seems loose, so IO tried my old Ybuffer, but back to blank screen.

Then I reinstalled the new Ybuffer and again had trouble to secure the top connector ... but then "click!!!"

Turned On the TV ... et voila!

Back to life!!!

Yeah, 40CAD$ isn't too bad to fix that not so old plasma!

Thanks for your help everyone!

BTW Tom66, would you have a recommendation for a good, but cheap$$ scope?
This is a piece of equipment I'm missing and that could be usefull from time to time.

Well pleasure didn't last ...

Tonight, for the first time since the TV is repaired, my boy plays is new game he received for christmas ... After about an hour of ply ... PAF...
No image again.

Same problem as last time.

Any idea what could cause this kind of recurrent problem?

Did you fully secure all screws for the Y-main & Y-buffer board?

As for a scope, what's your budget? $50-60 can pick up a decent analog scope. $400 buys a new Rigol DS1054Z, one of the best value-for-money scopes currently available.

Yes, all the screws were put back in place and properly thighten. Why do you ask?

Sometimes loose screws can cause the boards to fail.

Check your new buffer board for shorts. Shorts in same area or different area?
