Samsung UA65NU7300K Not switching on

[Grunder]

Good morning all,

This TV goes from red led to blinking 4 or 5 times then red led goes off.


1) The power on voltage remains at 3.23 volts and so does the OD on (backlight on command?)
2) The Backlight does come on when unplugging CNM801 and the voltage on OD on drops to 0.03 volts. From this Im taking that a zero voltage is the on Command?
3) The power on command does dip to zero momentarily when pressing the standby button.
4) The 13v rails measure 12.83 regardless if the TV is in standby or on possition.
5) Im guessing the Main Board is Faulty?
6) Replace or is there a fix??
7) Please any assistance.

PS Im trying to attach photos but clicking on "manage attachments" does nothing???

In this series "NU" is mainly a problem with the panel.

Thanks lotas, I have tried disconnecting the ribbon cables to the panel but the Main board seems to sense that the cables are unplugged and then the TV doesn't respond at all. I would have been p'd off if i had bought a new main only to find that the panel was buggered, thanks for the info. I see quite a few of these "NU" models starting to give problems.

I saw another post on badcaps where a panel tester was used to generate patterns to test the panel. Looks like i'll have to fork out some bucks and buy one.
