Here's my LMS 332c circuit board. I'm showing where the power source is on the lower right, and where I believe the first two ribbon cables that lead to the power switch on the front panel (upper left) are. Can anyone tell me how to disable the internal power switch and where? I want to install external switch and bypass the internal. I can solder and not afraid to try since this unit is out of warranty and is not functional as is with powering on/off and screen flashing randomly. I have 12volts to the unit and wiring is good so I verified this is a known issue with this unit and hoping someone has repair details.
Thanks much!
