SNES video (?) problem

Hi,

I got my SNES out for the first time in a couple off years yesterday and was pretty excited until I realised that it had developed a fault! I tried nba jam and all seemed fine until in game when the sprites and foreground graphics were all over the place and seemed to be jumping back and fore - completely unplayable.

So I cleaned the cartridge. No joy. Tried a few other games then... international superstar soccer had messed up graphics (blocks of colour and nothing else) on the cpu team select screen. In game graphics were fine but the game was not playable (on kick off game screen seemed to jump to the crowd and just stick there). Zelda seems to play fine (only 2 mins testing), super Mario world seems to speed up and the sprite jump to his death when he shouldn't...

So, I'm concerned there is a problem with the chips on the main board... anyone know if this is likely or whether there may be a more diy-friendly cause? I'd happily pick up a faulty SNES and do some part swapping if I can get a handle on what the problem is!

Thanks

It may be the cartridge connector on the SNES Console which is giving a poor connection and needs cleaning as well as the cartridge. Sometimes moving the cartridge in and out a few times and cleaning the cartridge again may help.

Yep! Also look out for any bent or broken pins on the connector.

The best way to clean it I have found is to use something like an alcohol dowsed j-cloth wrapped around a credit card and push it in and out vigorously.

The connector is replaceable iirc.

Thanks for the replies! I'll concentrate on the connector for now then... see if cleaning it up makes any difference :) I'll report back after I've had a play. Going to have to order a gamebit socket before opening it up though
