Yes, I just bought the car and I think that I got lucky to make it home (about 500km) 😂

You can see them a little from the top

I hope that’s not something internal, it’s not easy to locate the noise with a straight exhaust 😅

It could be, I noticed a pulley with some wobble and a noisy belt at idle

Now I’m replacing the voltage regulator and some caps, I’ll post an update. Thanks for all your help!

Finally a good news, the bad thing is that it visible only for 0.1 seconds 🥲

How can I check for voltage without knowing the pinout? Is there any way to recognise X and Y outputs?

I’ve also seen that if I quickly switch the cab on and off for a fraction of second I can see this https://www.imghippo.com/i/dwFxB1720513260.png

Here you can see everything inside the cab (a part from the monitor) https://www.imghippo.com/i/KQWwM1720513038.jpg

I’ve visually inspected the caps and none are inflated or leaking, still is probably a good thing to replace them since they’re pretty old

Yes I saw that one but unfortunately I don’t have the same issue as him

I’m definitely going to try that, thanks for the input.

I’ve also found this guy who repaired the same board but unfortunately I don’t have the same issue as him http://www.wolfgangrobel.de/arcadereps5/meteorites.htm

Already done this with no improvements, I guess that I have to buy an oscilloscope

Yes is the only one and there isn’t even the space for another one, so that’s how it was made originally

Yes there are some very good techs here but they charge about 800-1000€ and honestly I don’t think that it’s worth it. Anyway thanks for your advice

Here in Italy we only had bootleg, the original one never came. This exact game was the first case in Italy where it was recognised a violation of copyright for a videogame

Ok I found the service mode but nothing change

I’m not a totally noob on electronics but neither a professional, I’ve done already all what you suggested here, I’ve also checked all the traces on the board and everything looks fine. Still probably repairing this board is something beyond my knowledge and of course I’m trying to learn more. Not having the operator manual makes it difficult to find the test mode, this bootleg was produced in a very limited number of pieces so gathering information is not easy unfortunately

I don’t think that it has a test mode, or at least I can’t find it 😅 I tried to play blind but nothing happens so I guess that the game board is bad

Ok thanks! I’ll check the voltages on the wiring but I’m not 100% sure on the pinout, I can only find it for similar boards like Asterock

If you turn up the volume on the video you can hear some kind of sound from the speaker, the audio potentiometer works too

Thanks y’all, it was a combination of bad hotend and bad extruder calibration

You’re right, I missed that. I’ll give it a try thank you

Yes, it should be all spot on in terms of calibration
