I just received a keyboard which I purchased from ebay. It is one of the newer style Commodore keyboards.
The problem is that the Return and Enter keys don't work!! However, every other key works fine. Is it possible to repair such an old keyboard? What should I do ?
-
What should I do ?
Make the seller refund your purchase.

Nah unfortunately I can't it was advertised with "Is sold as is". Oh well.

Hmm if it's both Enter keys it sounds like it's not the actual keys but part of the circuitry inside the keyboard, unless it's just a coincidence.
I'd take it apart and see if there's anything obviously wrong with the contact on those keys, after that if you can't find someone to fix it get another broken keyboard (just one with missing keys or something) and make one good keyboard out of the two.
-
Easy way :
Get a soft lead-pencil (or whatever a "Bleistift" is in english) and
srub it over the contacts on the PCB.
If you don't find a PCB, but one of those foils:
Get an A1200-kbd as spare (used or from Vesalia).
Harder way (if the key is the prob not the pad):
Find a fitting "inside-part" of a key (the tiny plastic with the small
contact-pad).This can either by ripped out of another Ami-KBD or be
found in some Mitsumi/Logitech-KBD. Not for the shaky-handed ;-)

Nah, those (and space) are the most used keys,so they are the ones that
will wear out 1st.
I would guess that the seller used the enter-key as a replacement for
the long-dead return, till that also gave up :-(

Have a look at this post (http://www.amiga.org/forums/showthread.php?t=4092) of mine on this subject.
Also check the Amiga keyboard repair (http://www.nyx.net/~rdavis/AmigaHints.html)
Last week, I repaired a worn key pad of an A1200, by gluing a PostIt on it, after having sprayed the yellow card with graphite. :-) It works great.

You could sacrifice the tilde~ key or another under-used one, use the rubber key "feet" from an F Key etc. What I used to do. Its hard to tell, but these conductive rubber "feet" actually crack (split) sometimes resulting in a failed contact when you press 'em.
-
Hello Lo (I was going to put Hi Lo, but I thought against it ;-) )
Doesn't "seem" to be cracked, I could be mistaken though. I've looked on the web for Mitsumi keybaords of the Commodore nature layout, but to no avail.

Also C64 key feet work and are more durable, although they won't feel quite the same (Shorter key stroke)

LOL The Gods must be Crazy!
Sorry man, I was talking abit of Greek there.
Yeah, the C64 keystrokes are shorter, I prefer the feel of the Amiga keyboard moreso than the C64 one. You reckon that any PC repairer would be able to repair it?
-
Well I just tried roughening up both keys a little, cleaned them, but still nothing. Unless I have done something wrong or not adequately, I gather that the circuitry is broke. Looks like I gotta get a new keyboard thingy. But how would that nine-pin connector thing fit on to an A4000 from the A1200 spare keypad as Kronos suggested?
-
Just to be sure that the green circuitry foil is broke (even though might be repaired), try to exchange the conductive pads with other functioning keys. I know it's a pain in the ### (30 tiny screws on the back of the KB) but you should try this. A quick test of the keys is on the "Early Startup Menu", by pressing one key after another: if the key is OK the mode changes from Pal to NTSC.
You may also find me on GrNET (eu.irc.gr, gr.irc.gr or http://www.irc.gr for more info), #AmigaHellas ;-)

There are basicly 2 kinds of Amiga-KBDs (not counting those on A1000,A2000A and A600).
1)Contacts and KBD-CPU on one PCB, those came with the A2000, A3000 and early A4000.
There is also a version with 2 LEDs which was used in A500(+), another cheap source
for spares.
2) Contact-foils,ending in a ~20 "pin" foil-plug. Those came with the A1200 and newer
A4000 (only Escom ?). The KBD-CPU is either on the mobo (A1200) or on a small
PCB inside the KBD (A4000). These foils can be changed, but the A1200-version
has a longer "plug", so that might proove a a bit harder.
I also heard of some A500s having a foil-KBD, with the CPU-PCB.
-
Thanx Kronos (I hope you realise we are brothers :-D , me and CI5 that is, not me and you :-D ). We know someone with an old A500 who no longer uses it due to some problem, so we may take that apart and butcher what we want from it.

Thx to all for your comments :-)

:lol: There are more Greek Amiga users in foreign forums than they are in Greece. Anyway, it's good to know there are a few of us here and there. I have been trying to find some techies over here to discuss about Amiga h/w repairs but had no luck. I only found the ex-commodore technician and I had to beg to get my A4k for repair.... Still waiting for a battery to replace the existing one (leaked as usual) and fix my audio problem too. Ypomoni!!!
