Some on ebay too, also an eeprom available for 15 bucks but don't know if that's your issue: https://www.ebay.com/sch/i.html?_fro...fLoc=2&_sop=15

I was able to cancel my order.
This is a pic of the board that turns off the tv when plugged in.


TV model is UN55KU6290FXZA Will this board on ebay work?

tracked it down, you need version BJ04 or BA03. those two will work, if there's a way to make others work, I'm not familiar with it.

Re: Samsung UN55KU6300FXZA

many times unaware resellers don't know to or bother to take note of the version numbers, which can cause untold confusion.

UN55KU6290FXZA Version Number BA03
I'm not seeing many options when I search for it using those two numbers.

Re: Samsung UN55KU6300FXZA

you can try to match it thru panel number, yours should be CY-GK055HGEV5V, double check your panel number to make sure, should be on a sticker located someplace on metal chassis, thinking any board that came from a tv with that panel number should work.

You are right and I apologize. I thought our issues and model were similar and this thread could help rather than starting a new one. I will leave. I hope you are able to continue to enjoy the conversation.

How many blinks? which are the readings on the leds outputs with main board disconnected? if you pull out the Fail count contact from the psb>mb cable with the help of a mini flat screwdriver and you try boot up tv what happens? in an other manner, all things connected, try pressing exit key on RC for at least 15sec., last try, try enter service menu..

I got definitely non working PS from seller....When I power up TV, +8V goes to +13 like it should, but then PS shuts down...+13V goes to 0 and then STBY again(+8V).
If I supply MB +13V from external supply, and external voltage to working part of BL, I got working TV...:-)

I had the exact same problem and one of these diodes were shorted (one of these 2 diodes marked with the red pen). The only way to test these are removing it from the board. The shorted one has to be replaced.

Re: Samsung UN55KU6300FXZA

good policy is to replace both those diodes.
