All electrolytic capacitors. Please reduce V/Div up to 1 v/div. Also check again IC23 pins. |
| Harry_22:
Sorry, check the pins 8 and 16 IC23 |

Please next measure A0 and Q0 EPROM lines. Set up 2.5us/div or less to see the pulses. Move start trigger line to the left to see the full picture. |

G'day All, These motherboards are part of a controller for a piece of earth moving(drilling equipment) which is over 30 years old. It has therefore probably been exposed to a wide range of ambient temperatures during its working life and even when parked up, it's probably housed in a steel sea container. The OP does not have an ESR meter. I suggest that the OP replaces all the capacitors on the motherboard with new, good quality ones. Include C1 and possibly C10 if you think this could age. BTW What device is the WACOM Tornado T? All the WACOM links I see relate to Visual products. |
