Hantarex MTC 9000 – Model 04 – Can’t find schematics to identify a resistor

[gtparas]

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.

This is the back of the neckboard:

This is the board:

And this is the model of the main board:

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.

Found one:



It's 47 ohm.

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?

 

[gtparas]

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.
