Our 2015 2552 seems to have a bad coaxial cable. We just returned from a trip where we had to bypass the external connection near the power plug on the driver’s side and run some coaxial cable through the driver’s window and connect to the tv with a splitter. This “bandaid” worked just fine, we just lost a whole lot of “cool points” in the campground. I’m wondering if I could connect a new coaxial cable to the current one, using a simple extension connector, and then pull the new cable through using the original cable? Also, how long is the original coaxial cable? Has anyone had this issue, or has anyone had a similar experience? Looking forward to a simple solution.
Unfortunately, the only simple solution is if you forgot to turn the signal booster off when hooked to the external cable connection. That, or your jumper cable from the pedestal to the external connector on the PC is defective. Third easiest solution is to pull the signal booster and make sure the 3 coax runs to the bottom of the booster have not become loose. Of those 3 wires, one runs from the external coax connector, one runs from the outside TV antenna and the 3rd goes to the TV's coax connector.
You say you added a splitter to your TV's coax input connector. Did you first try to run your "bandaid" cable to the signal booster input that is next to the power button? If that didn't work, it would lead me to look at the cable from the booster to the TV. A quick test for that is to try the over the air antenna. Unless you are in the middle of nowhere, you should at least get a few local TV stations.
I agree with the earlier comment that you won't be able to pull a new cable thru using the old cable and that it's quite rare for a coax cable to just fail, unless some rodent tried to eat it. Pull the external cable hookup and look inside it, is the inside connection tight and free of corrosion?
Added in edit:
OH, forgot to tell you, you can get to the inside of the external coax connector real easily from under the driver's side bed. There is a plywood cover on the front of the underbed storage area that comes off easily via a couple of screws and gets behind the external coax connector.
