I have a Samsung PN59D7000FFXZA that when plugged in it displays the last source (HDMI 3) in the corner and then displays a Samsung Smart TV banner then it turns itself off and repeats this until unplugged. The Remote Control won't respond either as I tried to see if I could find a menu to reset...Any idea which board is to blame? I haven't taken the back off yet and can put up pics when I do if needed. The set is spotless otherwise. Thanks!

Re: Samsung PN59D7000FFXZA Cycling On Off
Most likely it's the main A/V board
Can you post a picture of your control/logic board? It's the centre most green board in the set.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung PN59D7000FFXZA Cycling On Off
Troubleshooting same problem on PN59D7000FFXZA. The unit will power up for 2 - 3 minutes and then reset. This is continuous.
Question: Did the problem get resolved by replacing the main logic control board or by component repair?Comment

Re: Samsung PN59D7000FFXZA Cycling On Off
Most likely it is auto upgrading firmware but failed to complete.
Try this to see if it helps:
When it shows the Samsung Logo, press MUTE 2 5 8 EXITComment

Re: Samsung PN59D7000FFXZA Cycling On Off
Thanks for your quick response. I tried the procedure you suggested several times with no change. The unit will power up with audio and video and then do a power reset after 2 minutes and 20 seconds. It seems to be very consistent timing. I checked online for software update and the unit is up to date. The auto update is enabled. Any ideas?
Thanks again. ReddPhreddComment

Re: Samsung PN59D7000FFXZA Cycling On Off
It's better to turn the auto update off. May be try to do a factory reset, mute 1 8 2 power
and choose to factory reset to see. Though you must do it within 2 minutes.Comment

Re: Samsung PN59D7000FFXZA Cycling On Off
Tried the sequence with no luck. I press the mute button and the muted symbol appears on screen. I enter digits (1 8 2) and press power button. The tv powers down. There's no factory reset in menu mode to do the reset. Not sure I am doing the reset correctly. There is no indication from tv that anything is happening. Is there something I am doing incorrectly? Appreciate the help. Thanks ... ReddPhreddLast edited by ReddPhredd; 01-31-2016, 01:03 PM.Comment

Hello everybody, I could use some help on this one... It's got me guessing...
