New Astro monitor failure?

[BDT]

Here are the photo's.

The NAOMI setup:



The Sega I/O





Inside the cab





Monitor connections





Inside the cab- monitor





Screen (not easy to photograph, but you can see the lines a bit




Hope this helps. Maybe something with the Jamma wiring?

i don't think i am wrong but difficult to see,your jamma connector is on round the wrong way

Maby first clean because you got allot of dust inside your cab BDT.
Dust and electrical don't like eachother

[BDT]

My Jamma connector is connected OK I think. Left is A above and 1 beneath. When I try to change the Jamma connector to connect it the other way, things can be broken I believe...

And Almighty, I never dusted the monitor maybe good idea, but will it fix this problem?

tell me why you think your jamma is on correct
i can see clearly pin 1,2 ground(white) and 3,4 +5(yellow) are connected to the left

pin1 of the i/o is where you can see the red arrow

BDT, please check your jamma connection, because I also believe that you have it connected upside down.

I know that you're not unfamiliar with a Naomi setup, but a mistake is easilt made. I did it once and I blew up my Jpac partially.

when I look at this pic, I'm pretty sure your connection is not good.



and i also noticed that your Sega I/O is resting on a metal plate (I believe). Perhaps this could cause a short circuit?

Did i mention

YOUR JAMMA EDGE CONNECTOR IS ON BACK TO FRONT

NO YOUR I/O BOARD IS UPSIDE DOWN YOU FOOL

Stupid me.... Japanese is front right to left, not left to right. In the past I always connected OK, but I made a terrible stupid fault...

It's working again, Yay!

Feelin stupid still....

the important thing is that it is working,we all make mistakes-when jamma first came out i blew a few boards up because of the -5v

So you were professionally present at the 'scene' at that time? That makes you a video arcade veteran, I guess.

yes i am that old,before jamma came out most operators had dedicated cabs except for the company i worked for-we had our own finger board system and all our cabs had the same wiring,we were in fact a prerunner to jamma

the first video i worked on was ghosts and goblins and it had just been released

It’s an easy mistake. I did it with a £300+ pcb not too long ago It survived thankfully.

It’s always usefulf to write “UP SIDE” or something similar on the Jamma loom edge when it’s not keyed. I’m sure it’s a mistake that you won’t make again. I’m very careful now ensuring that the Red/Black power wires are always to the left.

You gotta yank that monitor and shoot it with some compressed air.
