Punch-Out!! doesn't work on my AV Famicom

[jack of all trades]

Hi guys!

I've bought this Punch-Out cart on eBay: www.ebay.com/itm/281075652697

The game arrived today but unfortunately it doesn't work on my AV Famicom.
It just gives me an grey screen on the TV, the very same grey screen I get when I power on the console without a cart inserted.

I've cleaned the connector with q-tip + alcohol, and I also tried to pull the cart out of the cartridge slot a little bit.
But all I get is a grey screen. No garbled graphics, no sound...

I don't own another Famicom console to test the cart on.
Currently I only own 3 Rockman carts which  all work...

Is there a known issue with Punch-out on an AV Famicom?
Any suggestions what I can try or should do...?

Some games that works on my Famicom only shows a grey screen on my friend's Famicom, probably because he has a dirty connector. Have you cleaned the connector in the Famicom main unit?

If it still doesn't work you could try opening the cartridge up and file the pins down with a sand eraser or fiberglass pen.

Dirt and corrosion on either the game or your cart connector, guaranteed.  Unless the actual game is somehow cracked or broken which is unlikely.

Try blowing the fami's connector too.  This happens with half of the carts I buy, but they all work with a bit of blowing and inserting / ejecting.  Sorry I know that sounds awful.  If you really can't get it to work, get a refund.

Your famicom is obviously racist have you tried the regular version of Punch-out   

[L___E___T]

Take it you're talking about the NES games - that is the famicom's regular version, unless you're rich.

Thanks for all your suggestions so far 

The cart slot of my AV Famicom is clean. I also cleaned it with a credit card + microfiber cloth + alcohol. But the cloth didn't get dirty at all, the AV Famicom is in a really nice and clean condition. This applies for the inside of the console too.

A few hours ago I bought a quick grip to open the cart according to this video.

I cleaned the contacts with a rubber eraser. Afterwards I've cleaned them again with q-tips and isopropyl alcohol.
Then I resoldered all pins of the three IC's.
If you look close you can see some scratches on the PCB (not caused by me). I checked with a multimeter if the scratched traces are broken, but they're not...

Reseating or pulling out the cart a little bit didn't help neither.

I also contacted the seller and asked him if he tested the game before. He said the cart hasn't been tested because he didn't have a Famicom console.
The seller said I could send back the game to him. That would be an option but sending it back to France costs some € and I don't know if get a full refund.

Frustrating....

That is very bizarre, I would think after doing all the things you did the cartridge would have a 99.9999% of working. Don;t know what to tell you

notice: slot may be cleaned, but it looses his pins strength over the years of usage. If so the cart with thicker PCB will work fine.

You still didn't try sanding down the pins? I'm not sure it would help in your case though, since you didn't even get a garbled picture from doing all that.

I'm extremely sorry for bringing this old topic back up.  I was just lurking at old threads since I'm new to the Famicom and I needed to comment on this since I have an idea what the problem is.

If the OP is still out there then zoom in on the picture you took of the front part of the game pcb.  Look at the right side, to the left of the letters RM4.  I'm not sure, but it look like there is a piece of a trace between two traces.  Maybe it's acting as a bridge and making your game not work.

Also hold the pcb up to a light and inspect it for other broken traces.

Sorry again for bumping this.
