Problem MPU?

[snowvictim]

Czołem!

Co może powodować, że po ~15 minutach grania GI gaśnie, flippery, slingi, itp. przestają działać, dźwięku nie ma, DMD gaśnie, tylko światła oświetlające translite działają. Można maszynę wyłączyć i włączyć i nadal to samo - tylko światła na backboxie działają. Po około 30 minutach jak odpalam to wraca do normy tylko, że zresetowana do ustawień fabrycznych. I tak w kółko.

Miałem korozję na batboxie bo bateria wyciekała. Przeleciałem całe MPU octem, to zielone nawet też schodziło. Pojemnik na baterie i tak wymieniam bo to hańba. Ale z tego co wiem to ta korozja na batboxie nie powinna powodować tego gaśnięcia wszystkiego. Ktoś tam mówił, że może 5V nie dochodzi do MPU, tylko nie wiem za licho jak to zmierzyć multimetrem.

Pomocyyyyy!

Nie ma na to recepty w stylu: "weź dotknij tutaj i tutaj, tu przyłóż z piąchy a tam pogłaskaj i zaskoczy", zapomnij. Jeśli nie potrafisz podłączyć multimetru, to jego wskazania też nic Ci nie powiedzą - z całym szacunkiem.

proszę bardzo:

WPC-95 Driver Board LEDs, Test Points (TP), and Fuses.
For reference, TP107 is ground.

LED100/TP100: +12 volts DC regulated. Should be always ON. If off, check fuses F101 and F106 (or diodes D11-D14 and capacitors C11, C12). If fuse F101 has failed, this is often caused by a bad CPU board chip U20 (see the switch matrix section for more details). Though not likely to fail, there is also a voltage regulator LM7812 at Q2, and two 1N4004 diodes at D1 and D2. If fuse F101 has failed, suspect the voltage regulator Q2. The AC Power originates at connector J129 pins 6,7 and 4,5. It then goes through fuse F106, diodes D11-D14, capacitors C12,C11, LED102/TP102 (18 volts DC), diodes D1-D2, voltage rectifier Q2, fuse F101, LED100/TP100 (12 volts DC), then to connector J101 pins 1,2.
LED101/TP101: +5 volts DC digital. Should be always ON. If off, game will not boot. Check fuse F105 (or diodes D7-D10 and capacitor C9). Though not likely to fail, there is also a voltage regulator LM317 at Q1, a LM339 chip at U1, and two 1N4004 diodes at D23 and D24. The AC Power originates at connector J129 pins 1 and 2. It then goes through fuse F105, diodes D7-D10, capacitor C9, voltage rectifier Q1, LED101/TP101 (5 volts DC), then to connectors J101 pins 3 and 4, J138 pin 4, J139 pin 4, J140 pin4, J141 pin 4.
LED102/TP102: +18 volts DC lamps. Normally ON (can flicker with playfield lamps). If off, check fuse F106 (or diodes D11-D14 and capacitors C11, C12). The AC Power originates at connector J129 pins 6,7 and 4,5. It then goes through fuse F106, diodes D11-D14, capacitors C12,C11, LED102/TP102 (18 volts DC), diodes D1-D2, voltage rectifier Q2, fuse F101, LED100/TP100 (12 volts DC), then to connector J101 pins 1,2.
LED103/TP103: +12 volts DC un-regulated for opto lights, motors, etc. Should be always ON. If off, check fuse F109 (or diodes D3-D6 and capacitor C8). The AC Power originates at connector J127 pins 1,2 and 3,5. It then goes through fuse F109, diodes D3-D6, capacitors C8, LED103/TP103 (12 volts DC), then to connectors J138 pin 2, J139 pin 2, J140 pin 2, J141 pin 2.
LED104/TP104: +20 volts DC flashlamps. Normally ON. This LED fades off when the coin door is opened. If off, check coin door and fuse F107 (or diodes D15-D18 and capacitor C10). The AC Power originates at connector J128 pins 1,2 and 3,4. It then goes through fuse F107, diodes D15-D18, capacitors C10, LED104/TP104 (20 volts DC), then to connectors J133 pin 5 and 6, J134 pin 5.
LED105/TP105: +50 volts DC coils. Normally ON. This LED fades off when the coin door is opened. If off, check coin door and fuse F108 (or diodes D19-D22 and capacitor C22). The AC Power originates at connector J128 pins 8,9 and 5,6. It then goes through fuse F108, diodes D19-D22, capacitors C22, LED105/TP105 (50-70 volts DC), fuses F102, F103, F104, then to connectors J134 pins 1,2,3, J135 pins 1,2,3.
