Re: Samsung un55c6300 turns itself on and off

Also, there is a rusty red circle on the sheet metal back of the tv. Nothing on the board beneath the circle to indicate a problem. this tv was purchased directly from the installer, wondering if my folks got stuck with a refurb or if it just rusted.. This tv was at a beach house. i'll try to get a pic. thanks again, you guys rock!

Re: Samsung un55c6300 turns itself on and off

Well, I've left in unplugged for a couple days. Now when I plug it in, the clicking problem is gone and the screen comes on. If I turn it off, it turns itself back on again. I unplugged the cable to the main board and jumperd 16 and 18 together again. The voltage is staying steady and 5.2V and 18 is not not going up and down.. Do I have a capacitor problem?? Not sure what to do next.. Thanks

Re: Samsung un55c6300 turns itself on and off

More info.. Well, now the TV is not turning on at all. With the main board and the inverter (?) plugged into the PSU the board is clicking a lot. As I'm checking the voltage on Pin 1, a click occurs, I can see it come up to the normal level (12v) then it shoots back down. Another click, it comes back up to 12v.. With the PSU discconnected from everything and 16&18 jumped together, I'm getting this on the odd pins..

18 PWR On/Off
17 Vamp_18V 17.09
16 STBY_5.2V...

Hi, I've got a Samsung un55c6300 with a pd55af1u-zhs PSU. The TV is turning itself back on when turned off with the remote and occasionally shutting itself off when on. We watched it for a while and just unplugged it after use, but this got annoying after a while. I'm trying to fix the problem, but don't want to pay for a new PSU if the issue is somewhere else.. I'd also like to attempt to fix the PSU myself if that's the likely culprit. I pulled the board and checked the voltages with significant help from [URL="https://www.badcaps.net/forum/showthread.php?t=42938"]this[/URL] thread....
