Xevious problem...

[level42]

AR-II is fixed. Again a dead 2N3055. Judging from the color of the heatsink (was originally black, going towards metal color now) it gets pretty hot on this game and I can imagine because Xevious looks to have many bigger chips than f.i. Centipede so I'm pretty sure it uses more current.

Checked R29 and R30, both nice 10 Ohms.

All caps checked with ESR tester => fine. Didn't check the sound section but these rarely go bad.

I'll return it ASAP

Thanks again for your help André!

I installed the AR-II yesterday but the problem remains:

The light in the marque is working, the monitor is working, but i can't see the game, can't hear any sound when i insert a credit and also the player 1 and 2 buttons don't light up..

I tried installing the bootleg pcb but that one is jamma.. So what could be the problem? Is it the pcb?

First check all the fuses on the power-brick.

Then check all the voltages from the power-brick, especially 10,3V.

SOOOOOOOOOO, how are the fuses Pieter ?? ?? ?? ??

blown ?

The fuses are all okay.  

Before i can check the voltages, i need to know which is the 10v, ground etc. and the manual isn't helping with that:

So in other words, i need the xevious power supply schematics and i can't find any online

The fuses are all okay.  

Also the main one ? That is the main fuse that is in the surface of the brick, you need to unscrew the black cap.
