Gauntlet Legends (Vegas 777) freezed, then Error Code 6, Power issue

[lanny_2000]

Hi there,

Yesterday, we where playing this terrifc game in our cabinet for the 10th time and after 5 minutes, the game totaly freezed up. The screen was freezed and that's it, no reaction at all...then I powered of the system and started again...the LED display counts up from 1 to 6 and then stops...no reaction, no monitor screen, no boing...nothing. According to the error code 6, which should be the Hard disk (I am using a DOM module), I did:

1. Replaced my DOM module with a new one with the same image -> nothing
2. Replaced the DOM module with a standard IDE hard disk with the same image -> nothing
3. Checked voltage on my power supply and also on my power hard disk cable -> exact 5 Volt, others are 12, so its correct
4. I checked the LEDs on the CPU board and see that LED1 is constantly green, meaning that there is insufficient power
5. Already used another power supply -> nothing
6. Checked voltage on the Eproms -> 4,97
7. Even checked the voltage on U8A and get 3,2 Volt, which should be good

So now I am stucked. What I see is on the Sound board, the LED position 6 with the 4 LEDs in a row, the one from the right side is red...

Has anybody an idea what its wrong ? The system worked before without any issues and I even didn't have the "3 tabs to go" screen...

Is there a manual for all the codes which are displayed in the small LED display on the board ? 1,2,3,4,5,6,7,8,U,D, ect...

Any help would be nice...
