This is the final thing I did to my Sony xbr-55x900e, and it worked. 4 blinking RED lights main problem
The t-shooting chart above and just about all the stuff you read is total junk. (they got it right out of the maintenance book...which is easily obtained online).
The Youtube video showing a soldered wire on the 3rd or 4th pin of the LD board got rid of the 4 blinking lights.
THE last Solution that worked for me as seen on badcaps forum: (and, after the blinking lights, maybe, try this first)

Re: Sony Bravia XBR-65x900e Test pattern
Dudes! I feel so smart. One of the LVDS cables had a tiny bit of wear it looked like to me. I took a razor and sliced a few mm off, cleaned the ends, and voila It works. Wooooo buddy.
