Hey guys,
I have a meldas 500 on a Daewoo Puma 6S that occasionally will turn on, usually it doesnt. When I hit NC power and it does nothing (it might beep and I can hear the icecube relay in the controller click). Sometimes the screen goes all orange but doesn't display anything. I have tried all the easy stuff like reseating the boards and checking for damage. The QX141-1 unit has one red led (deep inside on one of the small pcbs attached to the main pbc).

It looks like I have good power but some random short causing this issue. But I know little about the Mitsubishi control so any help is appreciated.

The battery tested at 3v.

Thanks in advance!
David
