Short version is:
I forced a firmware update and it seems to have bricked the set.
Looking to see what my options are for repair; replace a board ? which one ? Anything that can be done over the serial port ?
I had a bit too much time on my hands and was trying to resolve some issues with using a Chromecast dongle on my LG 50PA6500.
Decided a firmware update might help. Not sure where I found this version of the firmware, but it was:
The set wouldn't recognize it through the normal update menu, so looked up info on the service menu - it saw the file and allowed me
to try and update with it. Failed. Set will turn on and just show an alternating pattern of pink & moss green lines, the power
cable needs to be pulled to turn off.
I'm willing/able to disassemble and replace the components, but have no idea where to start.
Any help or suggestions appreciated, thanks!
