Donkey Kong Issue

[NobleR75]

Hi my Donkey Kong randomly started to do this during gameplay(photos attached). Done the old ON/OFF routine but this still happening.
Donkey Kong Jr runs fine it’s just Donkey Kong. New to the hobby so would like some advice on how to solve this.

Where are you located? Looks like chips/connectors might need a clean and reseating and/or voltage checked.

You said Junior runs fine. Are you using a switcher or is this a double DK board?

Looks like bit 1 of the character graphics ROM is stuck low. First step is to reseat.

South East London;
this is my first machine so I’m buying things as I go. Voltage meter coming tomorrow (Amazon) also got o some contact cleaner.

I’ve pushed on all the chips in there and appear to be in place. I have a switcher that allows for Donkey Kong and Donkey Kong Jr to play, both on separate PCB’s. I will have to do the voltage thing tomorrow. Whole new territory for me lol

Bit far from me but if you reseat the chips be extremely slow and careful. So easy to bend and snap pins if you're not used to doing it and even when you are used to doing it.

Agree with Jerry , This looks like a ROM issue. Remove all , Clean with IPA and reseat (If you have fibreglass pen then use that). Re seat and try again.

Hi, I managed to remove and clean all the chips but sadly no luck. Still having this issue. Anyone got any suggestions?

Put a wanted post up and one of the members will reburn them ROMS for a reasonable fee.

i think you need to get rid of the cab, with the problem you have told us about its basically worthless now

i'll come and pick it up and dispose of it for you for no charge

Never getting rid of it😂, all part of the learning experience.

Update, cheers for everyone’s advice. Donkey Kong has been repaired and working beautifully.

What was the cause of the fault?
