Hi everyone,
I have just installed a "chinese McWill clone" on a GameGear borad (https://fr.aliexpress.com/item/4000283448700.html?gatewayAdapt=glo2fra&spm=a2g0o.order_detail.0.0.4c547d56vmgtyL). It presents a strange glitch the bottom of the display is duplicated at top (see my picture).
Do you have any clues about the cause of this problem ?
I was suprised that this lcd variant doesn't require to remove some resistors contrary to the other McWill clones. Could it be an error in the installation instruction and the cause of this bug ?
Thank you for your help !

Ask the support team from where you bought it.

Wait. There's probably 0 support for those clone products.

People try to save a few bucks then rely on free help on forums.

Sorry, buy the real deal and support creators/developers.

check the solder of the flat cable.

@Apocalypse There is not only the price. This clone proposes a good pcb improvement in my opinion : you don't have to use wires for most of the connections.

@EmuBoarding You mean the connector of the lcd ribbon ?

I have tried to remove the resistors and transistors indicated in installation instructions of the others McWill versions and it has changed nothing.
