One of the jobs I used to have was a communications tech. We often practiced the electronic version of a "precordial thump"... in other words, give it a good whack.

Incredibly, it sometimes works.

But like using a precordial thump to jump-start a stopped heart, it only works once. Keep whacking it and you will just be bashing it to bits.

It seems to me you have an intermittent problem. Giving it a whack might be re-seating something. And you probably flexed the chassis by using the removal tools, which might also have re-seat it.

I doubt Thor will have the wherewithal to do anything, unless of course the unit is still under warranty.

If out of warranty, realize Jensen is junk, and you are better off installing a better brand. I sill have that very same unit in my RV, and one of my projects is to replace it.

To remove the unit, you put those U shaped thingies into the holes in the front, which when you push them in, unlocks the tabs. However, you cannot pull back on the "U"s, otherwise, you will lock them again. Instead, grab around the periphery of the unit and pull it forward while the "U" things are pushed in.

Once you get it out, you might also want to check the connections on the back of the unit to make sure they are not loose.

On the other hand, since Jensen is junk, just whack away until it either works or breaks... at which point, you can replace it with something better (the Rv manufacturers are installing Sony or Pioneer units these days).
