Peschges VP3 Problems

Hi There,

I have a VP3E that is giving nonsense characters on startup. Have flicked all switches to no avail. Anyone seen this before? Is there anyone left that can service Peschges stuff?

Hi,

Could this be a problem with the LCD display contacts? Try cleaning the rubbers, ours had a lot of dust etc. in between the glass and the rubber contacts. You could perhaps also _very gently_ try to press the display edges and see if it helps to get a proper contact...

I had this problem earlier this year - it turned out to be caused by a faulty connection in the wiring to the battery.

The problem took ages to diagnose (because I thought the VP3 had just died of old age or had something wrong internally and so didn't test the circuitry). I finally discovered the problem because the connection deteriorated so far that the radio stopped working.

This one is quick and cheap to check, so I'd try it early on.

Just an update.

The wiring & the screen appear to be fine. I completely dissassembled the unit and found 2 watch type batteries, both dead flat, and both the original batteries in a 12 year old instrument. 5 years seems to be their useful life. I have a feeling that as a result the eproms contain no data!

Thanks for your help.

Nick.

So these things are not eproms!

They may be battery backed static RAM but I think the program was in EPROM in the Peschges instruments. The RAM probably holds data while the program is running and the batteries provide memory retention in the evnet of a ship's power interruption.

If the EPROMS are damaged you could always copy ones from another VP3.

Thanks Mike. In the event that I get it working, is it any better than one of your old b24-b25 systems?

Hiya, newbie here on soaring space. Found the site when looking for info about the Peschges VP3.

Hope this isn't going to seem like I'm hijacking the thread, but does anyone have an english VP3 manual? In electronic format if possible?

TIA.

Sorry can't help you but I'll ask around couldn't find in on Google either.
Maybe you can contact the company?

I'm begining to doubt that they exist. Plenty of people looking tho. But having said that, most of the posts that google finds are 3-4 years old, or more. I guess technology moves on, so lots of VP3's gathering dust now, or just plain broken.

Thanks anyway.

I was surprised that I couldn't find anything either but sure technology moves on..
