I bought a nice Dk jr today. I got home unloaded it and it came right on with no issues every thing worked fine. About 20min later I moved it and the screen colapsed down to a 1/4 strip from top to bottom. This is what I found when I took the back door off the cab "Pic's are attached. The vertical size pot switch had been replaced with a aftermarket pot switch. The monitor board vert pot had broke off and someone replaced it with a loose switch. Then I noticed that 2 of the wires had came off the switch. The wire colors are Blue Grey and Purple. The blue wire is still conected to the switch. What wire goes to what prong on this switch? Reconnecting this pot will it fix my problem????
