Samsung UE55JU6050UXZG

[Muenze]

Hi,

Saturday I have bought a Samsung UE55JU6050UXZG Screen which has a bad mainboard (the seller sais so).
The Seller has tried to repair the tv at a samsung service, or other tv maintenance service and they analysed it, and told him they could do nothing for him, warranty was expired and they couldn't get a new main board.

I removed the cover, plugged in the power supply, but without Mainboard and the backlight started working immediately.
I made a video from my next try with mainboard, i think its better than my crappy english...

Samsung Startup video

Can you tell me by viewing the video which component you thing is bad?

I already checked the capacitors on the power board, also i checked the voltages on the pins to the mainboard and they look really good.
I was hoping (when I bought the tv), that it is just a broken capacitor or something like that, but it seems they are ok.

I cannot check the t-con board but i think thats also ok.

Can you tell me why the blue light on the tcon board goes of every ~30sec?

I already ordered a used mainboard for this tv, at ebay.

Thanks in advance
Guido

No backlights with the main board hooked up? And you said you have backlights without the main board hooked up. If you have a volt meter, check the BLon pin that goes from the main board to the psu. I am thinking bad main board here, since BLon is generated on the main board.
