Replaced main board and no picture just music playing
Sony XBR-65X900C
I replaced the main board on my TV and when it turns on there is no picture, just some soft music. I get the green to amber flashing light on the bottom remote control sensor on the TV. I tried putting a thumb drive with the latest update in the usb and still nothing after several hours.
Thanks For you help

Lets start from the beginning, We were watching tv and switched the HDMI input to the one our apple tv was hooked to and watched that for a bit. We switched back to the cdmi that our Directv was hooked to and got a message on the sony home screen(something to the fact that had quit responding). We tried to select another input and this msg would just keep coming up. We then unplugged it and let it sit for about ten min then plugged back in, it came up with the "Sony" screen, then went black, and then went to a black screen with the light around the edge. Couldn't get any buttons to work now. We then unplugged and let sit overnight and plugged back in in the morning with the same results. I called Sony, no help there, then called Best Buy talked with Geek Squad member and he advised me that is was prob a main board(BTW Tv is only 16 months old). So I found a main board on eBay part # A-2072-588A , the main board part# that came out of tv was a A-2072-588B.

Now I have a black screen no "Sony" booting up, led is flashing between amber and green, and just some soft music. I can cycle it on and off with the power button now and it will just go to the white led but still no picture.
Thanks in advance
