Power relay is defective. All contacts are not opening when power is removed. Located on small power supply board, upper rt side. s 901 part# FJ00142 should be under $10, do a google search with part number and 50 sources will appear.
I would guess you missed a open resistor--there are only about 12 of them--how did you check them?
This set (43uwx10b) has a tiny blue micro switch on the front of the chassis---if you engage it from the front the set will go into the DECAM or convergence mode--let me know the CLU number on your original remote and I will scan and paste instructions---98% of the time if the set is wacked out and will not adjust one of the resistors is gone---ONE OF THE CHIPS GETS THEM.
