Star Wars Audio Issues

[oktobernv]

This just started today

Went to fire up my Star Wars upright and started hearing "pops" coming from
the speakers as the machine was warming up.

They are pretty consistent - about 1 per second.

Started a game and the "pops" continued.

During gamplay now, most of the "music" is gone and the "pops" also interrupt the game
sound fx.

Here is a You Tube video of the issue.

where do I start looking??


Thanks in advance.

Sounds like it's constantly resetting. The sound is equal to that what I hear when I switch from SW to ESB (or the other way around of course) and there's a reset when that happens.

You can also hear the sound and then the pop interrupts the sound...

Make sure your the sound-board is firmly pushed into the interconnect PCB. Also check the wire connectiong but that's not likely the problem.

Check loose chips on the sound-board.

Also: run the hardware tests

Thanks

I ran the hardware tests - everything tests "ok"

In fact, part of the way through the hardware tests the "popping" will stop

BUT, as soon as I exit the test mode and go back into game mode, the pops
return immediately.

Already removed the boards and re-seaded all the connectors, no help

Will try re-seading the chips on the sound board next.

thx

I had the same issue. Speech is Resetting on you (it sounds like it). I sent the boards out for repair AFTER i switched every socketed chip. I thought it might be the LS161 chips (not socketed / clock sync chips) but it was something else - the repair guy (Bills video service - great guy) - sent it back and I think 4460 chips?? I dont remember sorry to say. I am pulling the boards this week anyway and can have a look.

Thx for the info Jon

what was the cost of your repair?

Do you have contact info for the guy who fixed yours?

Thx Much

Jon

on the 4460 chips on the "sound board"?


Non socket-ed, I assume?

 

[jonathan1138]

Yes - All sound board. I was happy about that somewhat because it was a small board i needed to ship (as opposed to the BIG PCB stack). Dont take my word on the chip number - i dont recall. But i know it was NON socketed, and i know it was NOT the LS161 (clock sync - three chips).

Of course this may not be exactly indicative of your issue. It could be anything.

My suggestion - pull the sound board PCB wire / fire up the game - does clicking go away? If so, you know its that board.

Next, IF you can, switch all socketed chips with a working board.... if not, you can try the elaborate sound test in SW diagnostics - its in the SW troubleshooting guide and may lead you to a chip. If that turns up no results than its most likely a non socketed chip.

For non socketed chips there are 10 i think. When i get the cab off the wall this week i will have a look at what chip gave me the problem.

By the way - for clarity - i had the same exact issue (clicking constantly) with NO SPEECH. I did have music always though.

Just checked - he had sent me a spare chip just in case and i found it laying around - it was a 7931 chip that he replaced.

Jon,

Yes, I disconnected the sound board and the "pop" goes away

So it's definitely something on the sound board

Thanks again for your help

Just got off the phone with Bill from Bills Video Service @ 508-695-8891.

Said "Hi Bill, my name is Rob and I was referred to you from Jon from Mamaroneck on the KLOV...."

He cut me off before I could even finish my sentence and said "Star Wars??"



Yup. Nailed it!

Super nice guy. My sound board is off to him today.

Will report back

Thanks again to JON for all his help on this issue

Thanks. Bills good people - i can speak with him for hours (hope he doesnt mind) - he was an arcade repairman before he retired (semi retired!).

Let us know when you get it back up and running.
