Hi @clarkenick3

A 6x blink error code is a panel backlight failure either in the G board, the Panel module or the BMX Board.

Here’s a composite image of the error blink triage chart and the 6 blink error troubleshooting flowchart taken from the  [https://www.manualslib.com/manual/1378925/Sony-Kdl-65w850c.html#manual|service manual] which may be of some help. (see p.3, that shows that the 65w857c is also listed in this manual)

If it is a board or perhaps the harness, then it will be cheaper than a new panel (if you can source one) and definitely cheaper than a new TV
