KOJRO Retro innovations | We take on another C64, and don’t dare to blame everything on the PLA ! @kojroRI | Uploaded August 2024 | Updated October 2024, 1 hour ago.
This is another C64 repair video, but as usual, we try to squeeze in some useful information, even though the fault finding process on this one was rather short. The symptom or fault on this one was blank or black screen, and as usual we don’t scream PLA when we see that. We also look into testing power supplies.
I really love to do work on the C64, and I have yet to meet one that I could not repair, even though some of the ones with broken tracks and where someone has ha a go before me could be a challenge. This was a 466 board, and it’s my favorite C64, as it was the last one to officially hold an old 6581 SID instead of the newer 85 version. ( Yes I know, as always with commodore, there are exceptions )
The supplier of the power supply are retropowerpsu.com and I would advice you to ask for a swap unit if it measures as bad as the one here. On amp and 4.6 Volt is just too low for a power supply that is rated for 2A.
So please watch the video to the end, I can promise that you would learn something, even though it’s not as heavy on theory as some of my other vides.
