IT IS FIXED!
After some minor adjustments (VS/VSCAN), the voltages are perfect and it looks great.
To everyone who posted, thank you!
For anyone who might find this, I replaced these parts:

Re: Stumped on Samsung PN60E530A3F
Can I get a quick confirmation that C5160 is supposed to be 10uf 50v?
It appears I have a shoddy repair from someone, it's been replaced with 10uf 25v. They also used electrolytic caps and not ceramic. Will replace with ceramic.Leave a comment:

I also just noticed, these are not ceramic caps.
Will this matter when replacing them? Electrolytic okay?

Just got the boards back today.
Looking closer at the board, it looks like some of these caps have been replaced in the pst.
The key cap (from my readings) C5162, was replaced with an OST RLS 10uf 50v.
C5046 & C5160 were replaced as well. [B]C5160 was replaced with (10uf 25v) ?????[/B]
R5214 was also removed from the circuit and put back.Re: Samsung pn60e550d1fxza intermittent display issues

Re: Samsung pn60e550d1fxza intermittent display issues
I checked both the X & Y main for cracked/cold joints. Could not find any. The boards also look intact without burn marks, bulges, etc. I have many photos if anyone wants to see.
YSUS (vscan) starts around -175v, then drops quickly to -160v. Rated for -198 on the panel. XSUS (ve) reads about 80v, rated for 98v on the panel.
I sent both boards off for repair, but the repair center said they are both fine. Ran in an identical TV for 5 days.
I am not sure what to think. VA & VS...Last edited by pur1337; 02-16-2017, 03:38 PM.Leave a comment:

Re: Samsung pn60e550d1fxza intermittent display issues
VS and VA are right on.
Vscan was pretty low. Starts off around -175 and drops to -160/161. Rated for -198
I have heard adjusting the vscan can buy time?
I've seen some say that its a good idea to replace the buffers when replacing y-main?...Leave a comment:

Samsung pn60e550d1fxza intermittent display issues
Hi everyone!
To start, thanks for reading!
I have sound, but no picture - sometimes
Pink banding - sometimes
It presents like this:
Starting from a cold startup, TV turns on (with picture/sound) every time. However, sometimes I have pink banding.
The pink banding will either stay, or randomly go away / come back while watching the tv.
Eventually the tv image will fail, but there is still sound. Once this happens, the TV will not power back on if I use the remote or power button to turn it off and on. I have to unplug it from the...Last edited by pur1337; 02-01-2017, 04:35 PM. -
Re: New Members - please post your introductions here
Hi everyone,
I am here to work on my plasma Tv. I have a good idea what is broken already, but would like to delve into circuit diagnosis rather than just replacing the power supply, or x/ymain.
I hope to learn logs and get it fixed!Leave a comment:
