Dreamcast VMU: Horizontal Lines on screen, any ideas?

Fri, 01 Mar 2024 07:43:36 -0700

Hello

I am new to repairing so bare with me.

As shown in the image, the screen has horizontal lines and i have no idea on how to fix it. I have taken it apart several times and given it a very thourough clean. The circuit board looks brand new, soldering is fine, pathways are fine. The only thing i can think of is that there is something wrong with the screen itself and the rubbery things that the screen is attatched too. I have no clue on how to fix something like that and have found no repairs online for it.

Any help would be appreciated.

Cheers

Tim

Dreamcast VMU: When back of VMU is squeezed or pressed slightly the VMU will reset

Sun, 12 Oct 2025 09:43:55 -0700

I have 2 VMUs that will reset (aka long beep and ask for date and time) when you even slightly squeeze it. By squeeze I mean just grabbing it to pick it up, holding it in player grip, or putting it away somewhere like a pocket. Additionally, it will sometimes reset just by lying it on its back on a table or desk. I'm not sure if there is a misalignment with the prongs or what. I have brand new batteries in all of them and backing is screwed snuggly and secured.

Dreamcast VMU: Contrast issue, image over saturated

Has anyone found a fix for a contrast issue on the VMU screen. There is no manual adjustment. Is there a possible secret button combo or resistor/capacitor that has failed?
