You'll need a RGB SCART cable because there ist no composite (sync). :)

If it works and looks ok than it is ok. ^^

Thanks for the photos. Now I see, why your picture might be too dark with the standard resistor values on the bypass pcb: You are grabbing the RGB signals before the "final" resistors R17, R24, and R32. When you solder the wires to the other side of the resistors the picture should be fine with...

And what MVS do you have? :)

Cool! To what values did you change them and what MVS do you have?

Don't know - maybe bridging R14, R15, and R16?

Your backup RAM battery is probably gone. ;)

Maybe this or the wires are routed unfavourably in your MVS.

Nice! :) What was the solution?

That's like it should be (without any additional resistor and/or capacitor).

Can you test with another TV?

The soldering looks good to me. :)

You can try to bypass R13, but I would guess that the chip is maybe bad. Can you show some pictures of your pcb, please?

Hello, I've got a MV1FZ with an Z80 error. When I insert the Diagnostic BIOS (v0.19.a02) it says "all tests passed" and when I use an additional diagnostic cart it says "SM1/Z80 prepare slot switch ignored" (see photo). Pressing Start does nothing. The Z80 seems to be already replaced by the...
