That's all the information I have... it's in the sound circuit of Super Burger Time.

From what little I found, it's a digital to analog converter?

Just try'ng to track down a missing audio issue with this board and I can't find a datasheet on this thing anywhere. Any help would be much appreciated.
 
Simply go to http://www.datasheetarchive.com

I have a bunch of those chips here, but I really doubt you have a bad one.

The input to that chip should have data pulses that go in time with the music or effects. If they are missing then backtrack. If they are there, check the outputs of the chip. If they are missing then check the feedback op-amp off of pins 7/8 as a failure there is more likely.

Out of all the sound circuit issues I've fixed, I've never seen a bad one.

Uggg... an NOW I need to find a Super Burger Time schematic... It either late... or I suck at this stuff... Or, far more likely, both.

The op-amp has no activity other than a solid low at V-, and a pulse at V+ that syncs up with what would be game audio. Every other pin shows nothing (floating).

Thank you though, I like how you explain things... makes it easy for me to understand.
 
Thank you.

BTW, how did you search for this?
No problem, man. A Google search for "Y3014B" doesn't turn up much, as you noticed. Since the chip is a Yamaha, I tried "Yamaha 3014B" which eventually got me to your datasheet.

But how did you know it was made by Yamaha!?! ... are you a witch?

Kidding. I didn't even think of adding the manufacturer to the search... pretty much everything else I've searched for I just use the whole string of letters and numbers and it just automagically worked.

Now I know... and knowing is half the battle...
 
Okay, got the board back... sorry to necro this thread, I had to give the board back to the owner, but just got it back today to look at it again.

I've traced the lines down to the M6295 which, at a glance, blew my mind... and as luck would have it... is surface mount.

I brought the boards back to the bedroom to look over some datasheets before I finally pass out for the day.

I haven't traced the signals yet with the board running... just going to bed tonight praying that there is a good signal coming out of the M6295... I can replace a YM2151, but that surface mount stuff is beyond my capabilities.
 
What's wrong with the sound section?

The M6295 is a fancy D/A converter that plays the sound effects while the Yamaha YM2151 is the FM music synth chip.

The YM2151 goes with the Y3014B/YM3014B DAC chip.

I've never run across a bad M6295 but HAVE run across some that were poorly soldered. I've run across a FEW (very few) bad Yamaha FM sound chips, but never a bad Yamaha FM DAC.

Yeah, that did it. A little flux and 5 mins later she's working. Thanks.

I was paranoid as heck... it's hard finding any information on Super Burger Time. Turned out it was an easier fix than I thought it would be... I think I'm just going to start reflowing all surface mount chips on Konami boards...
 
Glad I could help!

The surface mount chips on ANY arcade board are suspect as the boards are easily flexed. I find that the Midway boards (MK3/4 and newer) and the Sega STV boards are by far the worst.

Any STV board that crosses my bench gets the 2 SH2 processors reflowed. It's generally what the problem is anyway. Run the slave CPU test and you'll see the problems on those boards. (It's a "factory test" menu option)

I try to steer clear of "modern" games... I'm more into the classics. I was doing this for a friend so he didn't have to send the thing overseas to get looked at. ... although I am enjoying the attract mode sounds as my arcade here at home is severely lacking in attract mode musics.

Thank you again for your help.
