Question about Nintendo Super NES Console

How do you fix a bad video chip on a super nintendo? I have already tried cleaning the 62 pin connector and tried different pins. The video is still garbled. I know it is not the game as the game works fine in another snes console. Any known fixes?

You could outright replace components. I know it's not the easiest thing to do, but it may very well be your only option.

My SNES won't continue to the loading page. How can I fix this problem.

Loading page? I am not aware of any SNES game having a loading screen... Do you mean it won't load the cartridge? Try cleaning the connector pins on both the cartridge and the system with a q-tip and a small amount of rubbing alcohol.

It is probably a bad chip on the main board.I used to work at United Radio in Syracuse,NY on Nintendos and would see that.I forget what the charge is to repair an NES,maybe $40?There should be a sticker on your console with the phone number to Nintendo to ask them about it,or you can google Nintendo to talk to them.If you send everything,they will replace the controllers,replace the board,and clean the games.It's up to you to determine if it's worth it.When I was younger,we used to take and cut a slim piece of paper,about 1/8-1/4" thick and put it over the pins and stick in the game.On Mario,it used to show you where all the hidden stuff was,if you got the right spot.Good luck!

My nes keeps shutting on and off do?

The flashing screen (or blinking light) problem is very common with the NES. The system turning off and on is caused by the lockout chip is not recognizing the cartridge and prompting a reset once every second. This problem is usually caused by either a bad 72 pin connector or your game contacts being oxidized with a greasy film or dirty.

The solution is to first clean your game contacts to see if that fixes the problem. I would recommend getting a game bit key and taking the game apart for cleaning, but if that is not an option, use a q-tip with electrical carbon cleaner (such as Deoxit) to clean the metal contacts. If your games are clean and you still have the blinking, it's probably time for a new 72 pin connector.

Well the problem might be with the ppu chip inside of the console the picture processing unit chip has gone bad then. Try cleaning the game packs out with quips and rubbing alcohol or maybe it's a faulty pin connected that you have purchased then for the PPU chip it needs to be replaced.

Nes wonnt turn on, but when it does red light is flashing

Did you replace the 72 pin connector while it was apart? This is the number 1 reason for NES to fail to load or flash. A brief search of "72 pin connector" on eBay should net you a new connector for about $5 US.
If you have already done this, and the problem is really bad then recheck your work and make sure everything is connected tight.
Also consider that allot of nes games were not taken care of very well, so if the problem is specific to a couple cartridges, consider cleaning them as they are probably not connecting well.
Good luck.

NES in Black and white only...?!

Thats quite a odd issue, and I have never heard or seen a case such as this. Maybe your color balance chip is fried? NES is a 20+ year old system, so I wouldn't doubt the NES may have more issues then just a lockout chip error or a new pin connector.

Possibility that flex cable from top LCD screen, which passes through right-hand hinge, has become damaged, torn or has slightly pulled out of its connector socket.
