I dont mean to take over this topic, but i have the same screen. its the LK-204-25-V, PCB version 1.23. i would like to convert it to ttl levels for use with a microcontroller. i noticed that Raquel said that trance_nation's board was set at ttl levels so i think it can be done... any help would be apreciated...

thanks

Okay, hmm, its very dificult to solder these.
is it possible to unscrew the screws and split the teo plates and sold on the other side?

Hi

I guess you were talking about screwing/unscrewing the D-sub connector, sorry but you can't do that.

What I can suggest though is use small pieces of wire to bridge the gaps. Wire wrap wires work good for these kinds of reconnection of broken traces on the PCB.

no i meant unscrewing the screws for the two plates so i can solder on the other side of the dsub because it was easyer to do that there. and so i did, now it work perfectly thx guys!
