Help With Super Nintendo Repair
I'm considering purchasing and refurbishing busted SNES consoles in addition to my little NES operation with the same intention. Can anyone post helpful tutorials or videos that explain how to properly diagnose and repair common SNES issues. I'd appreciate any help you'd be able to provide, thanks for reading

My suggestion which works for me, is to take a piece of cardboard and insert it like a game a few times, it'll clean the pins.. sometimes you have to double or triple up the cardboard, but most of the time it cleans with a single or double layer of cardboard.
Thanks for the suggestion Matt, haha.
Herb, I HATE DISCOLORATION! I've experimented with so many different solvents to remedy this issue; bleach, laundry detergent, alcohol, paint thinner. Some grime is removed but I have yet to return a housing unit to it's original gorgeous gray state
Have you ever fully resolved this issue?
the most common problem is dirty pins inside the snes..

Should I dip the cardboard in a particular cleaning solution, or should I avoid that all together and just use dry cardboard?
The game ender is a broken A/C plug on the system. The plastic in there... when that goes, game over.

Here's the recipe that makes even the yellowest SNES's look like new:
SAFETY WARNING!!!
You are warned that hydrogen peroxide is very nasty stuff and can cause severe chemical burns to skin and can also cause blindness if splashed into the eyes, if handled incorrectly. Usually, you can't buy stronger than 12% over the counter, as this is the maximum strength sold to the public and is used to bleach hair. If you want to try this, I would strongly suggest that you wear goggles and gloves to protect yourself.
Merlin's Original Recipe
The original magical "Retr0bright" gel mixture that was found to work is:-
1 pint (500ml) Hydrogen Peroxide, 10 to 15% strength (40 vol) (available from hairdressers' supplies, e.g. the 'Sally Beauty' franchise in the UK)
2 heaped tablespoonfuls of Xanthan Gum (available from health food shops or online)
1 level teaspoonful of Glycerine (available from pharmacies)
1/4 teaspoonful of "Oxy" laundry booster
Add the Hydrogen Peroxide and Xanthan Gum to the blender or liquidiser. Mix on high speed for 5 seconds. Add the Glycerine and mix for a further 5 seconds. Let the mixture rest for a minute then mix again for 5 seconds. A smooth, non-drip gel should have formed. This gel can be put into a dark coloured jar or tub (e.g. a coffee jar covered in tape) and stored, as long as you DON'T add the "Oxy" until you are ready to use it.
To use it: Spread the paste onto the yellowed plastic, and place under a UV light source. If you have a UV lamp, great. If not, the Sun works too. Just place the parts in direct sunlight and leave until it's back to the normal color.
Honestly, I don't even think you need the Xanthan Gum or Glycerine... I am fairly sure those are just to make the mixture more like a paste.
