  • Daytona power supply issue

    Wondering if anyone can help with a power supply issue from Daytona 1?
    I turn on my Daytona today after a long while & I get the low 5vdc glitch screen.
    Checking the 5v on the PCB CPU the board is only getting 4.5vdc.
    Adjusting the V4 pot to the maximum brings it up only to 4.6vdc.

    Can I "repair" the PSU in anyway?

    Btw this is a single player cab so I can't grab another PSU to check

    Thanks.

    I've had the power supplies repaired by Jomac.

      I think the member Cwispy on here sells kits to convert them to ATX power supply's too

        Unfortunately the kits are no longer available as I can no longer get all the connectors. Not surprising given they all went end of life a long long time ago.

          Fair enough, just remembered you did them

            These weren't compatible with Daytona 1
            Will replace the caps in the PSU & see if it helps

              There is a lot more to those PSU's than just replacing the caps. If you try and fix it yourself and fail, you wont be able to send it to Jomac as he will not touch something that someone has tried to repair themselves. Its just not worth it, and I can totally understand why, and I do the same.

                    I understand that "re-capping" the PSU might not solve the problem but I'll try it & see. I'm well versed in using my Denon desoldering tool so I'm not going to ruin the board.
                    I was hoping someone with some knowledge might have some advice on how to solve this issue that's all as I'm sure this would be one of the most repaired PSUs
