PAL snes has graphical issues!

in mid-late aug on ebay i bought a snes and once i got the screwdriver i opened it up for cleaning and to get rid of and super glued some of the plastic back (surprised
there was any fallen plastic since it wasn't that yellow) and when i finally cleaned it and plugged it in with the only game i have for it (super mario all-stars)
after the title screen, the graphics was messed it and it was allot worst once i got into a level and at the time i haven't thought of reviving old consoles for future
generations (and myself) and after trying to clean the pins on the cart it was the same so i went on google and the best thing i could find is that it has a faulty
video ram chip. if anyone wants i can plug it in and take some pictures of both the console's insides and the game, it's the one with the three dots showing under the
piece of plastic covering the unused expansion port and the sound part of the system isn't a box model no. SNSP-001A(UKV).

 

hello?

 

Only bump after a week has elapsed, please. Someone will reply eventually - have patience!

Standard fault-finding, really. Test power input, check RAM. It's certainly not going to be a simple fix and you'll most likely need SMD rework tools.

 

k ty, also won't do it again

 

Try cleaning the cartridge edge connector before you completely write the thing off....

 

What is the condition of the motherboard? You may have a damaged trace but as previously stated more than likely a ram issue..
Shame you only have one cart, could be a long shot but maybe the actual cart is at fault ie corrupted ROM ???

 

i have allot with a q-tip and windowliene/windex

i really don't know i think i will take the console and cart apart and see also could it be broken solder connections?

 

If you see anything suspicious int there pop up a photo

 

That's for cleaning glass, not electrical contacts. Go to Maplin and get some contact cleaner - well worth having if you acquire cartridge games.

 

My bet is the vram chips. Often they just need a reflow, but actual chip failures are common too. You would need at minimum a heat gun to remove the chips and a 15 watt grounded soldering iron to put them on, and a good amount of flux. I'd sell it someone would buy it just for the ppu and cpu chips.

 

Windex is conductive, it's the worst advice many people give.
