Amiga 4000 HELP!!!

[swoslover]

Update.

Well tonight I managed to have the monitor on for a period of time it is still faulty but if the cable stays in the right place it stays on!!

Neither the mouse (nor the keyboard seem to work.  Everything else is ok.  However it is very frustrating as I wanted to try hired guns and it needs to be loaded through WB

Thankfully the ports seem to be ok as the mouse will right click just not scroll.

If anyone knows how I can

There's some useful advice on this site http://amiga.serveftp.net/index.html

Have you checked the battery area? Has there been leakage in the past? That could cause problems with the mouse.

On the lock is an image of an arrow - mine is unlocked and points to the left. Which way does yours point?

The seller did say the battery had been removed.

He said that this in no way affects performance.

I have emailed him to ask whether these are problems he had experienced but no reply

I may have to take the keyboard apart make sure it's all intact.

It's just so frustrating I have dreamed of an a4000 for years and finally I have one.  

I have to say it looks so nice & roomy inside, all that lovely possibility for expansion!!

He hasn't lied to you because having no battery does not effect its performance but having a battery that's leaked all over your motherboard and destroyed tracks and chips does unfortunately effect the smooth running of your Miggy  :roll:

Your best bit is to have a good look around were the battery was and see if it looks ok and the chips around the area look alright.

Mine had a leaking battery that once I'd replaced it left my Miggy undamaged. I also replaced some of my leaking caps to get the sound back.

It could be a problem with the CIA chips.

Are these socketed on your A4000 motherboard?

@Boot :

 There is no socketed chip in any A4000 (except the two ROM chips).

in some 4000, the buster is socketed.

Hold on, the mouse will right click but not scroll? That's different than just not working. Do you have another mouse to try?

If not, have you cleaned the mouse? Remove the bottom plate, take out the mouses ball and use a q-tip dipped in isopropyl alcohol to clean the rollers of any debris on them. Then reverse the disassembly process.

Are there any bent pins on the Amiga 4000 keyboard connector? Also, is it an Amiga 4000 keyboard? It's not pictured.

I will give you guys a link and see what you think.

Personally I think that it is the responsibility of the seller to name any faults.  The precedent there (in this case) is set by the fact he mentions the battery as having been removed.

here is a link:

I have cleaned the keyboard and mouse.  They then appeared to work for around a minute before inexplicably not working again.  As they both stopped nworking at the same time does this help anyone?

Sorry for keeping posting, but really want it all to work

@swoslover

It doesn't help us to help you if we don't know that you've tried all the suggestions that have been given to you so far in this thread!!

I'd suggest stripping the system down and giving it a good clean.

Check with a known good mouse or try this mouse in another Miggy.

Keys can go dead on Miggy keyboards but it's unusual for the whole keyboard to die.

Check the voltage on the mouse pins.

Try the mouse without the keyboard plugged in, and then vice-versa. If one of them is causing the fault, this will help you identify which it is.

I tried what you suggested and the mouse worked (upon which I could have kissed you!) then mysteriously stopped, maybe there is a defective connection or something?

Sorry if it appears that I have already tried some of the advice. I have been doing it as I go along, the basic like cleaning I can do (just!)

Everything else seems perfect the floppy, hd etc all work well.

I read on another thread that someone else was having a similair problem with their mouse and it turned out to be a duff solder joint(s) on the motherboard connector!! A replacement socket was fitted and all was well after.

But that doesn't explain why your keyboard won't work!!

Have you tried a game that doesn't need keyboard/mouse input and seen if the joystick port is working or not?

There are a lot of capacitors around that area - I wonder if they've gone and leaked on your board and done some damage?

interesting.. it could just be a short in the mouse cable, or the pcb in the body of the mouse.
What happened when you tried the keyboard on its own?
Do you have an alternative Amiga mouse you could try?

No problem, fault finding can be a tedious and frustrating experience until :idea: it all clicks into place, whereupon it ultimately proves to be a very rewarding experience, with useful things learned along the way.

Everything else seems perfect the floppy, hd etc all work well.

That is good news!

The monitor lead itself has a cut almost like it has been lying under the monitor which has worn it away.  This is where the blue spark comes from and you have to hold both ends of the lead and push it together, I will invest in some tape as it seems to work ok when the conncection is secured.

I'm sorry, but it is absolute madness to continue to use a lead in such condition.  Not only does it pose a danger to yourself, it might well have caused your problems which, I note, are being pinned upon the seller.

Not so much 'buyer beware' but 'seller...
