Amiga 2000 problem

[QuikSanz]

And these big sockets, since it may already be damaged are easiest to remove destructively.   Put something under to protect the board and pry the plastic off the pins.  Then you can easily desolder one pin at a time.

Easy way is to flush cut the legs to get the socket out of the way, then use a solder sucker to suck them out of the board one at a time.

OP could try Silvo or Brasso first with cotton wool buds instead of emery cloth come to think of it. In any case, personally I'd use Silvo afterwards to get the pins nice and shiny.

Thanks guys!I will try to fix it...

I've washed a lot of electronics in dishwashers over the years, including complete CRT monitors when they were really nasty and have had few issues although it's best to remove the flyback and/or focus divider if that is attempted. Electronics that have come from heavy smokers are nasty and going through the dishwasher removes most of the sticky disgusting nicotine/dust sludge that makes them really unpleasant to work on. When boards are manufactured they are washed in a similar process to clean off the soldering flux and other debris. That said, you have to know what you're doing, some parts like potentiometers and switches are not sealed and do not tolerate such aggressive washing well, and dishwashing detergent is quite alkaline and can cause corrosion if it becomes trapped so I use only a very small amount.

For high value vintage stuff like Amiga parts I recommend hand washing in a sink, use a small amount of liquid dish soap and a toothbrush or similar to gently scrub the nooks and crannies. If the water in your area has minerals in it I recommend rinsing with distilled water or isopropyl alcohol. After washing, allow it to dry thoroughly, I use compressed air to blow all the water out of spaces under chips where it likes to become trapped, then I set the board over a heat vent for several days to allow it to thoroughly dry before powering it up.

Im assuming the guy didnt use detergent! Even just with water you have several problems:


1. High heat. Alot of these old components barely hanging on just the heat alone could ruin them

2. Breakage: running through high heat with water jets you can cause all kinds of problems with caps and resistors coming loose.

3. Toxicity for your food. Washing a corroded electronic board in a dishwasher can make your plates and cups toxic

so AGAIN PLEASE DONT WASH AMIGAS IN THE DISHWASHER,. and yes you may have further ruined the board by doing so luckily there is no shortage of a2000 mbs and they are cheap.

Where are you finding cheap a2000 boards?

"cheap" is a relative term. At least they show up on ebay pretty frequently, which is a lot more than I can say for 1200/3000/4000's. Thanks, hoarders.

[paul1981]

I'm sure the hoarders would love to buy up 1200's/3000's/4000's, but you said so yourself - there are non available. There are plenty of 1200's in the UK though, but A4000's and A3000's are more of a rarity here.

If I could find a cheap A2000 board I could maybe use it to get mine working.

Few questions:

When you switched the machine on did the power light flash ?
If you have a hard drive was there any hard drive light activity? Any.
Again if hard drive was the light on all the time for a while ?
Did the keyboard caps light flash on and off constantly ?
The screen monitor, was the image static or did it flash differing shades ?
When you pushed in the floppy was there any drive activity ?
Have you left the machine running for a long time and if so does the power light begin to flash, or stop flashing and stay on constant say. And if the screen is flashing after a while does it stop flashing.

I have an A2000HD with a mind of its own and its a bit like my old Austin A35 in that it wants a little TLC in booting. I always fix my computers by taking very tiny steps and just dealing with one thing at a time. Doing anything drastic could very well create more issues sadly. All is not lost though. A2000s are very hardy.

I will send the Amiga to an expert to repair it!I want the machine back to life...

Good luck. A2000's are durable, but I think when people hear what you've already done to it, most are going to be pretty wary.

I really wouldn't worry about it too much. Over the years I've washed literally hundreds of PCBs in the dishwasher. A couple of times I had some of the solder mask flake off but I can't think of a single instance where a component failure occurred. This was monitor chassis's, 80s motherboards, arcade game logic boards, expansion cards, you name it, when I was repairing this stuff pretty frequently it was nearly standard procedure to wash the stuff before I started working on it once I had done the initial checkout. As long as you get it thoroughly dried out I would be seriously shocked if any parts were damaged by the washing.

The board is one problem. But I wouldn't want to put my dishes into this dishwater afterwards anymore. (-;

For the most part water does not hurt electronics, as long as they are dried out before power is applied. Most components are sealed, the only thing you have to watch out for are things like switches and pots where water can get in and it's hard to get it out. Like I said, I did it for years, I for a while I was repairing a lot of monitors and boards that had been exposed to cigarette smoke or machine shop coolant vapor. The stuff is nasty, leaves a sticky film all over everything. Normally I ran them through the dishwasher before I worked on them, made it so much more pleasant. Literally hundreds of boards, it worked for me, but YMMV. In retrospect the potential for lead contamination of the dishes is a somewhat of a concern but that's in the past. Now I wash in the sink with a toothbrush when needed, it's easier to protect the labels and keep water out of sensitive parts without removing them. Final rinse with isopropyl alcohol makes it dry out much quicker.
