Title: SNES Garbled Video
Post by: Gypsy on April 07, 2017, 05:44:54 AM

Recently got a SNES and the video isn't working, it comes out messy and garbled up. Testing it with carts I know are fine. I opened it up and it appears to be fine. Any idea on what could cause this? I can get pictures if that would help.

Probably a faulty video ram chip.  I had a SNES with the same problem.

Are you sure it's not normal mode 7 and mosaic fades.  :-"

Yeah could be. RF had the same issue. :/

Assume this is a fix beyond my ability level.

Also not cost effective.  The price of the chip, and the time it takes to replace it, is not worth it when you can pick up a SNES console for $50 or less.
