Re: Panasonic plasma pn50b550t2f buffer or panel

interesting, i guess if i was faced with this I'd be thinking buffers or ymain.

What's tricky is the lines are around the centre, both sides of it so not a clear cut idea whether upper or lower which is why I was think ymain also a chance.

If I knew more about the samsungs it's be good. If it's possible to run upper and lower buffers on their own that'd be handy. the uper may be affecting the lower and vice versa or ymain.

Always a gamble, you can only try. Those vertical distortions on the right side are interesting. i guess you've tried the reseat thing for those boards

Panel...

Panel...

have you struck this before? That's a real surprise, glad I'm not working on it, would have been a disappointment.

What part of that fault nails it? Is it those weird vertical sections on the right?

It's a known issue with some Samsung panels, particularly the B and C series 1080p ones. It's a shame because these sets are otherwise quite reliable.

Bad YDRV ICs(buffers), bad soldering at YDRV ICs(buffers), or bad connection to plasma screen in the socket at YDRV module.

That is definitely a Panel fault

It is exactly how my friends panel died
