Pulsa P4 Needs Fixing

Post30 Jul 2010, 14:10

I am a newbie, so be gentle! :)
I have a 1975 Pulsar P4 Executive flick wrist. It works, but one or
two of the numerals have the odd missing segment. Can anyone recommend someone that would be able to repair it?
PS Many thanks to Ed at RetroLeds for his advice.

Thanks Jeff, but I already turned down that piece of work. It's a long slow crawl to the wirebonds on the underside of that chip(after unsoldering EVERYTHING from the edges of the board. Then I usuallly find it's not a wire-bond issue but a display driver issue within the chip, which leaves me with 4-5 hours of work for a $25 fee. One day when I am really bored I will work on all the funky P4 modules I have, but on a single piece basis, someone else can go for the glory on that. I'd rather build him a hybrid.

I agree... a full P4 strip is a pain but pays off if there are only a few segments missing.
btw. if you ever had problems with removing the flick in a safe manner I can recommend cutting the silicone at the edges and apply a few drops of acetone or nitro or other aggresive solutions to work their way through.
the silicone will not dissolve but it will weaken the grip.

any other ideas are welcome.
