I need the power board manual for Samsung LED TV series 8 with model number UN55B8000, is this available?

Hello, that set uses 2 LED strips that are no longer available and the 55" strips are physically too large to work, the panel from Samsung is no longer available, but some list it as "available -special order" but it's no longer available so how are they going to get it?. But to make sure they are bad, unplug the main board from the power supply and plug the tv back in, if they light, the main board is bad. If they don't make sure the voltage is there to operate them, if not the power supply is bad. Parts for a 10 year old tv are getting harder to find. panel part number is: BN07-01170A Techman 57

You need a 3D source.

It should be problem with Power supply of LCD TV Replaced New Board of same part number.

You will not have any luck, The Screen only uses RF for control. As far as I know there is no IR receiver on the unit or any RS232!! A nightmare for integrating this product into universal control systems.
