Hi to all, the screen of my arcade has been damaged and unfortunately, I didn't take photos of the board beforehand. As a result, now there's a burnt resistor on the neckboard, and I can't identify it. I downloaded a manual from the web, but it doesn't describe the same model I have, and the resistor is missing. Does anyone happen to have the same model to tell me which resistor is R212, or to take a photo?

My model is the following:

Chassis: Hantarex MTC 9000

Board: MZ 04 50144810

Neckboard: ZG 04 50144840
 
Can you take a picture of the neck board? I can look through my chassis later this week to see if I have a similar one.

Thank you very much for your time. I have searched a lot across the internet and I cannot find it. I believe it is made in Italy.
 
Thank you! Now I can continue the restoration. Of course, I still have a way to go, but the important thing is that I've unstacked. At the end of the journey, I will update with the result in the present thread. Thank you again.

I installed the resistor and it worked, but the colors are completely wrong. My problem now is that no matter how much I turn the color potentiometers, the change is minimal or none at all. I am sending a picture of how the colors should be and how they are now.

Has anyone encountered this before? Turning the potentiometers and they don't work?

I am also sending two pictures, showing how it is and how it should be.

Can you pull up a color bar test screen from one of the games?

Does the screen demagnetization / degauss work?
 
Theoretically, it demagnetizes. I hear it every time it turns on. I also did it manually, but it still doesn't help. However, you're right. That's the problem because I tried with a speaker from the stereo and the bottom part fixed. I need a degaussing coil, and logically everything will be fixed. Thank you again.

Hello,
I'm going to use this thread as I also have an old MZ04 chassis. As there is no schematic for the MZ04, I wanted to ask if anyone with an MZ04 chassis could measure the R91 resistor? Mine is completely burnt out and can no longer read the value. R91 on the newer 9000 chassis, where there is a schematic, will almost certainly have a different value.
Thank you very much.
 
Unfortunately, mine is cooked as well. First band is orange (so 3), but the second band could be red, orange or yellow (2, 3 or 4). I want to say yellow.

It measures 3361 ohm, so 3.4 kohm?

Can you measure yours?
