Re: Samsung HP T5064 clicks on and off, no picture
Thanks to everyone for your advice. I think I'll probably send this on to e-recycling.

Re: Samsung HP T5064 clicks on and off, no picture
I've re-seated all the ribbon cables on the y buffer board, but the lines are still there. I don't want to spend $ on a new mainboard if it's not going to fix the lines. Do you think I need a new Y buffer board (s) and/or Y main?Leave a comment:

Re: Samsung HP T5064 clicks on and off, no picture
Pushing buttons on the remote makes the blue light on the front flash, but doesn't do anything. So, I guess the IR unit is OK.
I've never heard any sound coming from the tv. Another point against the mainboard.Leave a comment:

If I reconnect the mainboard, with the jumper on pin 5&6 on the logic board, then the test pattern displays, but it power cycles again every 20 seconds.Leave a comment:

Re: Samsung HP T5064 clicks on and off, no picture
I disconnected the main board, shorted ps_on, and got the test pattern to display, thanks to [URL="https://www.badcaps.net/forum/showpost.php?p=399860&postcount=10"]this helpful comment[/URL]
The display patterns show with all the colors and stuff. I see [B]two thin black horizontal lines on the screen[/B].
I also found a bulged capacitor on the Y bus. See pic.
My completely amateur conclusion is that I have a faulty mainboard.
What would cause the lines?...Last edited by bwaindwain; 07-02-2016, 03:46 PM.Leave a comment:

Re: Samsung HP T5064 clicks on and off, no picture
I have checked with a magnifying glass and can't see any cracked/loose solder joints on the power board.
I've unplugged all connectors from the power board except the one to the mainboard CN801, and it still does the clicking.
On the mainboard, I've unplugged all connectors, plugged in AC, and it does the clicking thing.Leave a comment:

Samsung HP T5064 clicks on and off, no picture
Yesterday, my neighbor gave me a broken Samsung HP T5064 50" plasma. I've never seen it working properly. When I plug it in:
- the blue light on the front flashes five times
- there's a click from the power board (starting up?) and a very faint hum
- the display (backlight?) comes on very dimly, dark grey with two horizontal black lines,
- three green LEDs come on the small board under the mainboard (two steady, one flashing),
- waits for about 20 seconds,
- clicks again (off?),
- repeat

Hi. Neighbour gave me a broken Samsung plasma that I would like to tinker with and resurrect if possible. I own a multi-meter and soldering iron. Thanks.Leave a comment:
