Weldex backup camera issue
I have a 2003 Gulfstream Sunvoyager 33 ft. motorhome with the Weldex backup camera system. This RV only has 3,500 miles on it (dont really use it much) and the camera used to work the first few years we had it. Now when the RV is put into reverse, the monitor comes on, and I can hear sound, but the picture is white, ie, no picture. I tried reconnecting the cables to the monitor and trying the other input on it but no difference. I have not yet attempted to take the rear camera down, as the cable for it that goes thru into the fiberglass is puttied/caulked in place. If i dig this out and pull on the cable, will i be able to reach the other end of the cable where the camera gets plugged in? i dont want to risk digging this out if im not going to be able to reach the connector. I can just recaulk it yeah, but this is still a brand new RV to me. Everything is still perfect as the day I got it. Just wondered if anyone else had this brand of RV with similar issues. Since it doesnt get used much, im not really looking to spend a few hundred dollars in upgrading the backup camera. I would just like to troubleshoot why it doesn't work any longer. It looks like the cable coming out to the camera screws into the back of the camera so i dont know if i would be able to connect it directly to the monitor to see if its a cabling issue. any other suggestions to try troubleshooting this?
