Need some help again..

During game play the sound is going very quite at times (I'm not sure, but it seems to happen when you destroy the saucer, but not always). All speakers are making sound, just almost inaudible. The sound comes back fully when the ball is lost / next player starts.

On suggestion, I've tightened all the screws holding the boards and ground wires. I've also reseated all the connectors.

I'm open for suggestions... hopefully someone has seen this before and has a solution.

Thanks in advance.

Thanks for the reminder. The game is only resetting when I run a sound test. It has happened twice now when I run the music on repeat.

Hope that piece of info help.

Thanks

I'll check the sound EPROM and let you know. I've reseated everything. I wish it was just that.

Wed bump.

Ok, the game is running 1.0 sound so I've ordered the 1.1 chip. I'm not fully sure that will fix the problem as the 1.1 chip isn't designed to fix a game that resets and has sound drop outs, but it is a start. I'm open for any other suggestions...

Thanks for the help markmon...

When it goes quiet, I put my ear by each speaker and I'm about 100% certain all 3 speakers are playing, but very very quietly.

I'm not super great with diagnosing, but if you tell me where and when to test the voltage exactly, I'll put a multimeter to it and report what I get.

thanks!!

Yeah... wish I did have a spare. Any suggestions on how to proceed. I talked to Michael over at Flipper Fidelity extensively yesterday and we don't think it's the FF kit.

worst case I can buy a new sound board for about $275. I just want to be sure that's the problem. New amps and other parts are pretty cheap.

Not sure... I've put the "help" message out locally... but nothing really coming back.

Let me check.

I believe BOP uses the 89 board... damn.

Well I went ahead and purchased on of those brand new AV boards. The good news is this will allow me to test this and hopefully fix the problem. I'll report back when it's in house and installed... fingers crossed.

So I put in the new rottendog A/V board and turned the sound to about 27 or 28 for testing during a game. The fuses on the rottendog board (F501 and F502) blew after about 5 mins. I see they use 250V 1/2A fuses.

Anyone else had experience with these boards / fuses blowing?

If it's not one thing... it's another... :-/

BSL

Well new fuses with lower volume have not produced a sound drop out yet... more testing needed.

Now my strobe is acting erratic and the LEDs around the big saucer are all lit and not rotating.

Any ideas on stobe + LEDs out there?

BSL

ah... so I purchased some 3a 250v fuses as well... should I change out the 1/2 amp 250v's with these?

I'll have to look what 601 and 602 have... this is good news if that fixes it. Now to figure out why my saucer LEDs are not rotating (they all just stay lit) and why the stobe is acting flaky.

Markmon... I owe you a beer for all of this!

Also confirmed by Rottendog... replace 1/2a fuses 501 and 502 with 3a fuses. They didn't compensate for louder volumes.

yeah... thanks for the help along the way. Only bad part is the sound fix cost me almost $300!! Ugh.
