Re: Samsung PS58C6500TK pink banding issue and more
I did see a thread on another forum where someone was experimenting with some of the many settings in the service menu with an element of success with pink banding.
Im clutching at straws!

Cheers Tom the helps is appreciated.
I have gone right off Samsung! I really used to think they were good maybe they have gone down hill over the last 10 years?
So no way I can diagnose the screen any further not got much to loose at this point?...Leave a comment:

Re: Samsung PS58C6500TK pink banding issue and more
So I pulled out these two boards for a visual inspection. I cant see any dry joints, anything burnt out or obvious.
Running out of ideas to be honest! I could reflow the Inductors on the off chance but only going by something I saw on another thread for an LG screen. One leg of the inductors are covered with a piece or rubber awkwardly but could pull this off if it was worth while.
Any further ideas out there??
Could I swap a ribbon to see if the pink fault moves or is this not possible?...Leave a comment:

Re: Samsung PS58C6500TK pink banding issue and more
I noticed a few threads having a little success by resoldiering the inductors?
Might be the next port of call and a good visual inspection.Leave a comment:

When I run certain colours as a test background from a laptop the pink distortion doesn't show and the image is fine.Leave a comment:

Hi guys sorry its been a while.
Just been busy with work and decorating little ones bed room.
Tom I managed to do a few tests but struggled to find the Yrr / Yfr controls and test points maybe you could point me in the directing if there on this model? I did do some searching on Google and apparently some screens dont have this adjustment?
OK Results so far:
Vs: adjusted +/- 15v and there was no change at all.
Vscan: adjusted -15v and + 6v (POT wouldnt allow further) no...Last edited by Baileybum1234; 12-14-2015, 06:35 AM.Leave a comment:

Re: Samsung PS58C6500TK pink banding issue and more
Ok,
I have triggered the test pattern from the control board. The image still has the same fault.
I made a video of the check:

Re: Samsung PS58C6500TK pink banding issue and more
The issue is still a pink distortion that comes and goes with different colours.
Im starting to think there was more than one original problem.
Mostly at the top but some times running down through the screen.
There also looks like there might be wavy lines in the pictures. I think these happen so fast I cant see them there is deffinately something up!
There is distortion on the pictures due to mains Hz so please ignore the vertical bands thay are only in the pictures...Last edited by Baileybum1234; 11-13-2015, 03:36 PM.Leave a comment:

Re: Samsung PS58C6500TK pink banding issue and more
This only partly fixed the issue. So I adjusted VS as the next step.
It was originally at 206.9 when it should be at 209.
I took it up to 209 then to 213 and back down to 209 and the fault remained during this process....Leave a comment:

Ok so I have a Samsung PS58C6500TK.
It had the pink banding issue please see attached pic.
I was looking at another forum and they suggested updating the control board firmware - I did this.
Excuse multiple post but trying to keep the stages I have taken separate.... -
