UPDATE : Blocking off VGH VHG_ODD VGH_EVEN AND CLK4 fixed the picture completely I figure line 13 was CLK4 (line 16 to 13 is 4)

I could remove the resistor/fuses on the buffer board for these (VGH need to be cut) but probably no difference from masking off the t-con output?

Not crazy about the xbr's but now if I run across one with similar issue, I know what to do.

One thing positive about these XBRs is they are incredible thin (females seems to fans haha) and surely edge lit which provides a very even backlight. The cheap HiSense and TCLs I've worked on try to go thin with stuck on reflector paper with standard backlight bars. Almost never go back on with even backlight... probably wasn't that even coming out of the factory haha.

I hear that, the 65x900c I have, most of it is 3/16 of an inch thick, on the bottom part with all the boards add a little thickness but it's still like less than 2 inches thick in that area, very slim indeed, too bad I messed it up.

Thanks for the updates Howard. I have been a little "burnt out" (pun intended) with the Sony TV but I will keep your fix on file when I try to "erase" those lines again. Glad to hear that you finally found the source of the problem. Congratulations!
