Hello all, I need some help figuring out whether the TV can be fixed.
The symptoms:
a. TV powers up, tunes to a channel, there is picture and sound, and after a few seconds it powers down, with the standby light blinking 6 times.
b. Sometimes, it will power down after a few minutes, and yet other times, it'll stay on for hours.
c. The service manual (see attached) says to check JL9106 (Backlight_mon) on the board. It reads 1.6V in standby, it fluctuates for a second or two on powering up, then it stabilizes to 1.6V, and then drops to 0V when it enters the protection mode with the 6 blinking lights. According to the flowchart, it is the LD board that should be changed. LD board was changed, but the problem remains.
d. The only readily accessible boards are the LD, BAXL, and TU. In this model, I think that to get to the TCON the panel needs to be disassembled. I wasn't able to find any service manual for the LCD panel for these TVs (RB2G chassis).
Any ideas on what to check, would be appreciated.
Thank you
