Diagnostics and fixes

If your computer is down and you don’t know how to fix the bug, I’ll take care of it. Don’t risk further damages.


Based on my experience with Commodore, Atari, and Macintosh computers it can be very often a faster and cheaper way to get it done. Most of the faults are very often related to broken traces, faulty capacitors, or components. Using a microscope and proper schematics for troubleshooting is a better way to do it. Don’t risk damaging Your board even more. Send it to me for a full diagnostics. For Amiga Error coded, please refer to my article published here: http://retrospection.pl/?p=1567 . This page is constantly updated.

Ultrasonic cleaning

Ultrasonic cleaning is the best SPA for our precious retro computers. But mainly is a tool to clean up rust and dirt from the old mainboards. 

Before finding a fault on retro boards first step is to clean them properly. All traces and solder joints will be clean after this treatment. When I’m finished with the recapping I always clean them using this method from remaining flux, debris, or dust. Board is super clean between every element and even in hardly available places for other cleaning techniques. So your bord is super clean and ready for fun.  Just please use gloves when you put your mainboard into the case. 


Your Audio is not Working, or its a matter of the video flicker or strange colors? 

Very often, old components for a replacement are not available in the stock anymore. If I can’t find a proper part, there is always a solution to a problem. For Amiga, we can replace reset timers, video, or audio chips. With a few modifications, we can make them even better. Let’s add some extra chip memory. For Atari let’s modify mono to stereo, and experience the new sound quality. There is always a way to make our computers even better for our requirements.

Recaping Services

When electrolytic capacitors are getting old, they start leaking corrosive fluid onto the mainboard.

The corrosion can destroy traces, caps pads, or other components on board. If the computer is left in high humidity conditions, corrosion can go even faster. Don’t wait too long to get your computer in a good shape. I can replace them with new ones. You can select electrolytic, polymer, or tantalum capacitors. It’s up to you if it fits the board specification. I can do it in the full range of Commodore and Atari products and most of the Macintosh computers from Macintosh Plus to a Power Macintosh

The standard recap service costs are about 45 EUR.

Please read this carefully. The standard recap service cost is about 45 EUR. This price includes only low ESR electrolytic capacitors. If You will choose tantalum or polymer capacitors price may change. Replacing capacitors is not a solution for all potential problems on the faulty boards.


All boards can have invasive corrosion, broken traces, pins, and pads. If the computer is not working after cleaning and recapping its needs do be diagnose, witch I will charge extra for it. Some computers may have a larger amount of capacitors to be replaced, and therefore the charge will be greater. I’m not taking the responsibility for old brittle plastic parts (mainly connectors) or broken pads beneath the capacitors. I will do my best not to damage them, I’m here to help, but from time to time they just fail. Ultrasonic cleaning is a gentle process but it may cause discoloring or even removing labels / stickers on the board.


Send me only a motherboard without extensions or extra accessories.

If I will not have a working power supply for you a will notify you about it. All shipment coast are on your side. Thank You.
