Right... ThorRut's point was rather than removing/unplugging the radio, he uses both kill switches to remove all power from the radio....
Removing the radio is simple with the right tools... Two u shaped wires that go in the four holes on front of the radio. I remove and unplug everything.. leave it for a couple of days, then plug it back in and try it.
This has been known to circumvent (not fix) the issue for a period of time. Eventually it will fail again.
Alternative is replacement... But the RV212T and it's initial replacement of the RV215 have both been discontinued... The next replacement is in another thread here...Rv9xxx something...
Switching brands is an option, but the Jensen is the only one I know of with 3 camera inputs. You will need to add a trigger switch to any other unit to feed into the single camera input.... Or use a separate monitor for cameras.
(You can also try calling ASA (makes Jensen)... They might help on a replacement....)
