Amiga 1200 does not work

[alphadec]

Good job in the replacement PSU and LED lights lead.  Usually when people have mouse problems the issue lies with a CIA chip, or occasionally with Paula.  Might be obvious, but have you confirmed that the mouse works correctly on another system?  Have you tried your current system with a different mouse?

This doesn't change the recommendation to have the caps replaced, btw.  It's cheap and good preventative maintenance, since those caps can leak and cause a whole host of issues.  Just giving you a couple other things to check, as well.  

I have a Amiga 500 and used the mouse on that, with noe problems so the mouse is checked on that before I connected it to the A1200. But guess I will let amikit have a look at it.

Well done. Strange but the last Amiga 1200 I had a problem with the mouse was broken along with the power lights. I once picked an Amiga up from a guy and I watched with horror as the guys dad was cleaning an A500 with the power on while swapping out connectors on the back. I said that he should avoid plugging stuff in and out like that while the power is on. He just laughed and then offered me the 500. I have also seen forks used for removing floppies and kids pushing sharp objects into PCMCIA slots. Little wonder that the things are busted. My A1200 dates from 1993 and has been used and generally unplugged since that date and still works fine, even the floppy drive. Nothing has ever broken on her. Wonderful machine.

I have brought so many Amigas back to life and just get a very happy glow when I get them working. Many computers suffer from travel sickness. My worst was an A4000T which took a year to get working again. I am pleased to say that all my Amigas work and I wouldn't have it any other way. Certainly helps collecting parts and bits and pieces and never throwing anything away.

Anyway, good luck. Keep your eye open for motherboards on Ebay and the like. Often much cheaper than getting the computer repaired. Also getting junk off Ebay is rewarding. I once bought an A500 marked as a 1200 for next to nothing and when I opened her up she had a Viper 520 inside with a hard drive.

Enjoy your 1200. Truly magical.

Thank you all for all good advice. I love watching ebay so much u can find there. I never got round to getting a Amiga1200 when they was new, I was waiting for the AAA amiga that was to come out the year after!..... but the year after commodore was no more
a sad day for me.

I have done some more checking on my A1200 and found some more issues. Looks like the reason why the mouse dont work is because one of the pins on the port is pushed all the way in.....

I will replace the port but I was started to think is there a way I can check if the PAULA and CIA chips stil works. ?

Pins being pushed in is a not an uncommon problem for joystick ports on 1200s and 500s; it's that bloody back lip that stops you from seeing the sockets from above so people just prod and push.
Anyway if the pin is not bent you should simply be able to carefully push it back out again from the inside. using a small screwdriver. Remove the floppy to one side and you will have clear access.
The actual pins have two tiny flaps on the sides that should spring open to hold it once it has been pushed back in place. Unless they have buckled.
If they have buckled you can still take them all the way out and straighten them but you will probably have to unsolder the bas eof the pin.  
If it's going to Amiga kit they can do all this for you.

I have connected a external disk drive and the drives works so hope that means CIA chips is okey. I tried pulling out the pin but it is stuck so I have orded a new port and try to replace that before I send it to amigakit.
