1989 Reatta CRT problem

[carbuff]

My 1989 Reatta CRT screen that controls radio, climate, etc. at times the total screen seems to float slightly. The controls work fine. Is this a problem with the CRT or the CRT controller module or just normal for this unit?

The CRTs do eventually develop problems. Like with mine, the bottom half of the display will "sizzle". There's a rebuild service for them by Rex. I don't remember their contacts but someone else will chime in on this. I don't think it's that bad, like $125 or something.

Had the same problem with mine. The whole screen moved around about 1/16 inch. I was on long bridge between Tampa & St Pete. As soon as I left the bridge, the picture stabilized. Think maybe it was caused by the remote tv cameras or radar on the bridge.

I had the bottom two lines on the screen start shiver for a while until the car warmed up. The car had been sitting in the very hot garage for a while without being driven. Perhaps the heat got to it. It only happened a couple of times and hasn't done it since. Electrical problems have a tendency to be intermittent so it may come back. It is now winter and I keep it out of the salt here in Michigan: Michigan puts 22 tons of salt per mile on its roads each winter.

Wonder if Detroit automakers have a lobby effort to go heavy on the salt ( = increased corrosion = shorter life cars = sell more new cars )?...

That's normal actually. It's caused by your passing through the magnetic fields that the bridges' metallic construction creates.

Good theory, but this is a prestressed concrete bridge. Not a lot of metal. Will try to remember to watch in the future. Thanx, Jim

Probably. From what I know, some snow-states don't use salt and only use sand. I once told my dad that I'd rather be in the ditch and have my truck get rusty (again)

This is the link to Rex Services.

It takes a few seconds to load the opening page but, it's worth the wait.

There is indeed a great deal of metal (rebar) in prestressed concrete, and more consequentially, it is layed out in such a manner that when you are driving over it, you are passing over one magnetic field after another. Drive over any elevated structure (wooden covered bridges excluded) and you'll witness some degree of screen float.

I happen to be an electrical contractor and have seen all sorts of weird happenings on CRTs due to electromagnetic interferance in the course of my work.

I'd be willing to bet the farm on this one. <img src="http://forums.aaca.org/images/graemlins/grin.gif" alt="" />
