Taito F3 "Volume" dial setting
- Thread starter waiwainl
- Start date
I went to turn on it on to test a new game and only got a color screen. Tried out games that I one worked and it was the same. Cleaned the contacts, tested continuity and made sure voltage from power was correct. My in Sister in law came by that same day and her son was in my room next to the arcade while I was upstairs. The MoBo didn't have a game in at the time. I can't say for sure he did it, but I feel like I've ruled out everything else.
Can you snap a picture of the dial as it is now ?
Also there used to be a label on your chip stating chip version, can you post yours ? Like ESP REV 6 ...
This is how I measured mine back in the day...

Just wanted to put an update on the issue. The problem was voltage. The PSU read 5 volts but there was a .5 voltage drop to the jamma edge. I raised the power and it works, but now I have 2 MoBo's cuz I bought one after troubleshooting lol. I didn't even think there would be a voltage issue like that.

Voltage always drops over a harness, one reason I try to avoid jamma extenders.
I put little 2 wire voltmeter on the end of my JAMMA harness.
The easiest "good enough" way to check is at the JAMMA edge. The best is to check 5v/gnd on an IC on the board, but generally I only have to do that for futher troubleshooting.

I touched the fucking dial (moved it "slightly") but the game runs without Issues. Can i thank my lucky star and enjoy a round of Elevator Actions Returns or do i need to get that dialed back in before using the board further?
tl;dr is the dial set right if the Game plays with sound?

The dial is related to voltage on the video circuit from what I understand, if it’s working now I think you can thank your lucky stars and leave it
If you turn it up too far it apparently blows out the video custom
I’ve actually been trying to get hold of one where this has happened to check a few things. I have seen and fixed no video faults on F3 where the custom was fine, and I’m wondering if those same things would apply if the voltage was turned up too high

The dial is for the reference voltage for the Ensoniq device. Each device is calibrated individually so...

Well it still works according to OP so I guess be thankful and don’t touch it any more

Thanks for the Info, played to stage 5 and nothing blow-up in my face so thanking the Lucky star it is 
This post is a bit old but I couldn't find more information for my problem.
A couple of weeks ago I got this pcb from Arabian Magic and I noticed that the ensoniq 5701 chip and the ensoniq 5510 chip are burned and it seems that the previous owner adjusted the potentiometer, thinking it was the adjustment for the volume level and I think That is the reason the chips will be damaged in addition to a polyester electrolytic capacitor. Now looking for some junk pcb that has these chips, I found one for sale but I see that my ensoniq chip is espr5 and the donor pcb has an espr6. Would there be a problem if I use the espr6 chip instead of the espr5?
