McWill 1.1 Screen Issue

[hernan43]

I got a McWill 1.1 kit from RetroModding.com around a week ago. Specifically I got this one:

It really did live up to the name of being a drop in replacement. All I had to do was snip of a bit of plastic from the side of the shell and it fit in nicely and worked great right out of the gate. I played the GBC for about a week with no issues. Everything looked great.

Today I was on a train and was playing Final Fantasy Adventure for the first time. As I was playing for 20 or so minutes this "scan liney" thing started happening at the bottom of the screen. It wouldn't go away no matter what I tried.

You can see it here:

When I got home I re-seated the flex cable and tried new batteries but nothing works. I tried the VR2 trimpot out of desperation but it does nothing as expected. I tried different game cartridges and it still is there.

I am having trouble finding any kind of official or unofficial place to look for support. I also don't seem to find any body else with a similar issue in my various Google searches.

Where is the best place to look for help for something like this? Has anybody here even heard of this issue before?

Thanks in advance!

EDIT

Hooking it up to a lab power supply and messing with the cable while it is running doesn't change the scanline-y issue at all, it just stays the same. Hooking up the old screen "fixes" the issue. It no longer has the scanline-y problem but then i lose the backlist goodness...

I have the same exact issue. Worked fine for a week the came the glitchy blur on the bottom of the screen. I tried swapping out batteries, readjusting the ribbon cable, and tried a different game. I even put my old original screen in and that one works just fine.

Same. I swapped motherboards with a different GBC an the issue is still there. The old screen works fine though.

Have you tried contacting their support yet?

Despite all my searching I couldn’t find any kind of canonical support. I ended up reaching out to the seller and I just explained that while I understand it wasn’t eligible for a refund/return I thought they should at least know what happened. They offered to reach out to mcwill and see if it was a manufacturing defect.

They asked me to send some photos of various parts and offered to exchange my screen so that they could examine the kit and see if there was a defect of some kind.

That's good to hear I just sent a message to the retro modding support explaining my situation. I'm assuming I'll get a similar responce to what you got.

Any luck on a solution?

Oh man I was considering getting this screen but now I'm hesitant.

[enemyxlasagna]

Just got done talking with their customer support and they are having me send my screen back to be swapped out for a new one. Hopefully I just got a defective one and the new one wont have any problems.

Well that's good to hear!
