Schematic for Samsung BN94-04357A Main board anyone?

[jcamerox]

Hi,

The board is from a Samsung UN55D6500VFXZC led tv. The power supply seems okay because the backlights come on with the main cable disconnected and then with the main connected, the power cycles on and off, relay clicking every 5 seconds. No audio or video. I was able to find a service manual but all it has is block diagrams and cable connectors. Need the electrical schematic for the main board. Thanks.

As far as I'm aware Samsung don't release schematics for main boards.

Not for ones this new, certainly. They did for some older models.

Thanks for the replies Hamie and tom66. I will stop trying to find one and concentrate on getting a replacement board. I was trying to find out why there was no power going to one of the on board voltage regulators, one of the few components I might try to replace on a main board.

Is the power supply outputting 5V & 13V?
Check PS ON signal - if not LOW or changing when turned on, can be main board fault.
