I just got a house of the dead machine, and the monitor has a problem. At least I think its the monitor, and not the gameboard, as I can still heear the sound. When the game boots up, the monitor just shows a thin white horizontal line across the center, and that fades after several seconds.
Any ideas?
If this was the same problem I had, which it could be, then it's a major pain in the ass to fix.
On my Nanao, there was a very tiny resistor that was the cause of the vertical collapse. Sounds like a simple fix, right? Wrong. This resistor is in the single worst place any resistor could possibly be on a pcb. There's a large metal shield right in the center of the board, L shaped. in the very corner of the board, mashed between two caps is this resistor. If I remember correctly it was a 2.2k, but don't quote me on that. I just cannot get over how hard it was to replace because the L shaped shield stands tall, so you have to use extra long needle-noses or something similar to place the new one in.
The only thing that differers between your problem and mine is that the horizontal line in the center didn't fade away, so this sounds like a bigger problem. Let's pretend theres no vertical collapse, what would make the picture fade out? Flyback?
I also want to point out that the Nanao I repaired was the dedicated one that ships with VF1-2 cabinets. I have a feeling this was the same one used in HotD, and it's not the MS9-29a. But I could be wrong about that, HotD may house a 29".
