This is home entertainment but it is a stereo.....
I have a Jensen CD stereo in my truck and when I go out to drive somewhere, I get nothing but steady static. I press the station scan button and it acts like there are no stations to be found. Eventually it tunes in. If I leave the radio on one staion it does the same thing- suddenly comes on fine and is good for the rest of the day.
It's almost as if the tuner electronics have to warm up or something. The antenna is fine and all else works fine.

It sounds like it could be a loose connection somewhere. What do you mean by the antenna is fine? I would check the antenna connection to the head unit and check continuity between the antenna lead and the actual antenna. I have never heard of a tuner needing to warm up.

That's what I did with the antenna- clipped my meter to the whip and leaded the connector. She was good.
I never heard of a radio having to warm up either but it was the best description I could come up with.
I checked to make sure that the face connects to the body firmly.
I was wondering if the tuner has a seperate wire to power it and if it's possible to check that connection. Off to a schematic?

The radio finally let go. Only one channel would play. I went to Wally World and got one of those all-in-one stereo and speaker kits for under a hundred bucks and WHOA!
Great sound. It was picking up stations in Nags Head, an hour south of me.
It could have been the tuner circuits letting go as far as I see. It also cleared up a problem I was having with a battery drain while the truck was sitting for a while.
If I remember correctly, the old car stereos I messed with had the tuner connected to the "always hot" lead. If there was a short in mine, it could have been doing things like pulling juice form the battery at a good clip, round the clock.
Anyway, that car stereo special was a good deal.

It WAS the stereo. Since installing the new stereo, I have been enjoying better sound quality. The best part is that today, after being gone for a month, in 20 degree weather, the truck started up just fine.
Stupid Jensen crap. A simple malfunction in a tuner caused a lot of head scratching.
