Samsung HPT5054, HUGE PAIN IN THE ASS

Re: Samsung HPT5054, HUGE PAIN IN THE ASS

Awesome work

Well, it works, but there is a lot of green, grainy distortion in the highlights of peoples faces (sometimes referred to as the color/chroma being too "hot" or as solarization, diffusion?); I've seen this many times and sometimes can adjust something on the power supply or Y-SUS, but not sure on this model. Can you help me out? Normally, a little of this issue isn't too bad, but this one looks pretty severe.

Make sure first your voltages are in spec as per panel.

Okay, I will check the VS, VA...anything else? And there should be an adjustment potentiometer either on the power supply or maybe the YSUS?

On the Ysus, there are some pots that you can adjust. Mark their positions before you adjust any. Very tiny adjustments! Watch the picture as you adjust the pots.

The VS and VA are correct, but I am going to set this up to try adjusting the pots on the YSUS (carefully) and see what happens.

Okay, I was able to get rid of the picture issue by adjusting the pot on the lower left of the YSUS (label covered by board sticker). So happy! It's finally done!

That will be the Yfr pot probably, I normally set these up the following:

VS:214
VA: Keep at factory
VE:104
-VSC:-200

That normally keeps the panel in these totally sparkle free.

Thank you, Reecey!
