I mean the ribbon on the Ben Venn LCD, as damaged cables can result in a flipped image like you are seeing.

I would check that the ribbon cable for the LCD hasn't been damaged during the swap.

Thanks for the kind offer! I have decided to go ahead with a new Mcwill screen though, I've done a couple on the Game Gear and they are great. I did look into a Ben Venn screen but almost everything in their store is out of stock and I can't wait months for one. That's not good, was it definitely the screen? Who are 'Best' by the way, I may need a replacement OEM for my Lynx II so it would be good to get some leads.

Schematic here, power jack is in the bottom left corner. I don't think you need to do anything if the pad on one side is intact as they go to the same place.

I picked up a Lynx I on Ebay that was in really nice condition on the outside but has a bad screen. I recapped it hoping that might do something but there is no change. As you can see it has vertical and horizontal lines. Strangely the horizontal ones start to disappear as the Lynx has been on for a while and some of the verticals too. Has anyone fixed this or is it done for? I was expecting to have to replace it but I will try a fix if it's possible!

Check the voltage output from the ac adapter, I believe it should be around 12v at the output connector as it's an unregulated supply.

Well it's reassuring to know these are genuine from Marco himself, though if I ever sold my GG I think I would have a hard time convincing anyone that it was a genuine Mcwill screen.

It's interesting that he didn't say why he was selling the old version of the board. I'm fairly sure mine was a clone board. it was a lot cheaper than any others I could find by about £20 (but not as cheap as buying from Aliexpress...) the paper sticker just looks wrong the newer red version has apparently been around for a year now it didn't come with a VGA connector or any printed instructions Would be good if McWill could advise, but I guess he is a busy man.

Update: it's working! I could kick myself - the problem was the R25 resistor, although it appeared to be soldered down, when I checked it again it was showing as open - resoldered it and boom it fired into life. Very happy! I also switched over the C36 wire and removed the Csync wire. Thanks for your help!

So confusing - I don't think I have the latest version of the board do I? Mine is green (and probably a knock off). Since Retrosix sent me 2 capacitors and a resistor I followed the guide that incorporated those, which also said replace R24 with R30. I do still have all the removed parts so I could put it back on. It's something to try I guess. I'm hoping one of these things fixes it, otherwise I may just scrap this and buy a genuine kit from a reputable store (which is what I thought I was doing).

Oh should that not be there? The guide said leave the backlight wire but didn't mention CSync - I will disconnect it. I did play around with the wheel and it made no difference. I like your wiring, that's neat, maybe I will rearrange it!

It looks like I soldered BUT3 to the wrong side of C36 - will switch that over tomorrow. I wonder if that's the cause? I'm fairly sure it's a knock-off then, I was suspicious when I saw it and the price was too good to be true.

Hello all, I am fairly new around here. Today I decided to upgrade one of my GGs to a McWill screen. I bought it from Retrosix. Afte fitting, I get a blank screen, and no sound. I've check the voltage and the board is showing 4.82v, and I've been over the connections and all looks ok, I've checked continuity and for shorts on the LCD wires and they were all good. I didn't receive any instructions with it so I used those found on other sites, and since Retrosix included capacitors I followed the earlier version guide and replaced them. I didn't receive a VGA port with it. Does anyone have any idea what the problem might be? Also, does anyone know how to tell whether it's a genuine McWill kit and not a chinese knock-off?

Hello - new here! I am in the UK but would love to buy one of these when you are able to ship it here. Could you please add me to the list? Thanks.
