Not sure what you're asking there. Tell me where to find that and I'll look it up

Re: Samsung UN55D6420UF Power Cycling
Well, I just did the one for now. Everything seems solid. I gotta say, a little investigation and 5 minutes with a soldering iron definitely beats paying someone $300 to try and fix it.
Thank you all for your help!Leave a comment:

Re: Samsung UN55D6420UF Power Cycling
Just got home from work. Grabbed the board and gave the line leading to that joint a little wiggle and the solder joint wiggled right along with it. Hopefully that's all it is...Leave a comment:

Yeah, I have the back of the board another good look last night, focussing my attention around that transformer and that is the only solder connection that looked at all out of placeLeave a comment:

Re: Samsung UN55D6420UF Power Cycling
I haven't had a chance to try resoldering yet. I was messing with it a little more this evening. Once it would start cycling the power, if I grabbed that transformer by the plastic lip and pulled on it a little, the cycling would stop and the TV would be fine. As soon as I let go it would begin cycling again. I did this several times with the same results. Also, everytime the power cycles there is a pop/click coming from that transformer.Leave a comment:

Re: Samsung UN55D6420UF Power Cycling
Ok, so the acting up has gotten bad again. Pulled it back off the wall this morning and took the back panel off again. All of the boards seem to be secure, screws were all tight. Once I got it to stay on I started to lightly press on components on the PS boars with a small piece of wood. Every time I put a little pressure on the lower left of this component it would cycle the power. The top and lower right didn't do anything, only the lower left of it. I did it several times to make sure it wasn't a fluke. None of the solder joints appear to...Leave a comment:

I put it back together for the night. I checked the function after each panel was reinstalled and it was fine. Once I hung it back on the wall it started to act up but only once or twice. Then I was shifting it on the wall mount and as it slid roughly across it it cycled off and on one time. So I did it again and it did it again. May be a loose board or bad solder. I'll pull it back apart tomorrow and check things as you recommended.Leave a comment:

Re: Samsung UN55D6420UF Power Cycling
Ok.....so, with the back off of the TV and it leaning screen down against the back of my couch, I plug it in and now it's working. It hasn't cycled off once in 5 minutes. I bulged the back panel back in and have turned it on and off with the factory remote, the back panel and my universal remote. It's just sitting there mocking me.Leave a comment:

Samsung UN55D6420UF Power Cycling
Hello all. Found this forum while researching an issue with my TV. The thread that drew my attention was this one:
[url]https://www.badcaps.net/forum/showthread.php?t=30572&highlight=Samsung+power+cycling[/url]
Decided to start an account and see if I could get mine figured out as well. My TV now has essentially the same issue, just after power up it begins to continually cycle off and on and continues a few times after unplugging. Mine didn't start this bad though. It started doing this a few weeks ago. After a few minutes of being on it would cycle once or twice... -

Hello all. Found this site via a google search for issues with my Samsung LED TV. Seems I'm not the first one to have the wonderful power cycling problem.Leave a comment:
