Thank you for the advice. I will work towards having one in my possession.
I'll update the thread when I have done so.
Thank you very much for your time, the help has been greatly appreciated & a good learning experience so far!

Re: Samsung PN50C550G1FXZA - Dark Display with ''Sparkles''
Measured Vsc at - 189.6, sticker at -190
Unfortunately I do not have an oscilloscope, perhaps there is one at our office, I'll have to check later
I did not see round red capacitors on my y main that were similar to the ones I tested on the xmain. Instead I tested one's that were red, but flatter, and more rectangular in shape. They read 209.7 on two and 150.3 on another.
Below is the image of the items tested on, first is what I tested on the y-main, followed by what I believed to...Last edited by HamSa1ad; 10-11-2014, 11:48 AM.Leave a comment:

Okay,
With black on chassis & red on a single probe on each cap, I got a reading of 104.6 on each cap, working my way down through all 4 of them
Testing the other probe on the same capacitors, in the same fashion, I got a reading of 14.39Leave a comment:

Re: Samsung PN50C550G1FXZA - Dark Display with ''Sparkles''
Excuse my lack of knowledge,
But what setting should I be using to test the voltage accross the capacitors, the same DC Volt setting as prior? Also, does the unit need to be powered off & discharged or is this something I could test on the spare xmain I have?
Thank you for your time answering my simple questionsLeave a comment:

Re: Samsung PN50C550G1FXZA - Dark Display with ''Sparkles''
Took a few liberties is the time between responses.
I returned the original X-Main back to the unit & tested its Ve: 72
I scoured the Fast Track Troubleshooting Manual for my model (many thanks for having such items neatly hosted!) and found out what the VR-VE I noted above was for.
I adjusted the Ve back to the sticker. I turned on the unit for a test and saw the attached.
Didn't notice much of a difference in terms of darkness. Although it appears that more of the display...Leave a comment:

Ve is at 69.9
Originally I had measured VR-VE, at 91.2
Sticker shows 85 for Ve & 73 for 2VeLast edited by HamSa1ad; 10-10-2014, 05:53 PM.Leave a comment:

Samsung PN50C550G1FXZA - Dark Display with ''Sparkles''
Hello BadCaps Community!
I have a Samsung PN50C550G1FXZA which suddenly began showing a dark display with what appears to be a form of sparkles down in the lower right-hand corner (when facing the display). The image actively changes when I swap around inputs, but does so with what looks like a strong image burn. I had previously received some information that led me to replacing the X-Main, but doing so has led to no change in the display.
When the issue originally occurred the set was powered on & functioning normally, then abruptly changed to what appears attached...Last edited by HamSa1ad; 10-09-2014, 07:06 PM. -
