wurlitzer 1015 cd bubbler no sound

a friend has a 1015 cd bubbler. he had it hooked up to a external amp/receiver. he moved to a new house, and after the move there is no sound, not even a hum. it is not hooked up to a receiver anymore. i looked all over for a setting or switch that might need to be put back to original, but can find anything. cd's play thru, no rejection. the display in the amp shows a " 1". i understand from the manual its a software number, but it also looks like ( from the manual)its supposed to move past the one to another display. i havent a clue how to get him going, and feel like an idiot. its probably something simple, but i just cant find it.

thanks

The amp model would help, sounds like it is a K-99 amp though. If it is
a K-99 and you have the metal cover it has the dip switch settings
printed on it.

Otherwise you can download the K-99 amp manual he

that is the amp, and i have that manual. according to the manual, when you turn the juke on, the amp display should show a 1, then just the upper and lower horizontal segments should light, the lower for Ok, the upper for mute. that signifies standby mode. the unit never gets past the 1, it stays on 1. nothing in the manual says why, or what to do about it.

thanks

I'm no expert on the K-99 amp, never had to service one in the over 100
machines we sold, however the LED indicator is supposed to show which
switches are closed. So if it is always a "1" then see which switches -
if closed - would give you that result.

It might be as simple as the machine is in BGM mode all the time and not
accepting regular input. The amp has not computer it is only controlled
by a few inputs outside of the audio in/out so it should be fairly
obvious what is happening.

If you are still stuck I'll take a look at the manual and see if I can
offer any further suggestions, but really, this is pretty basic
amplifier DIP switch settings as I recall.

i was flippin dips in different combos, no help. i turned the juke off before each time i changed dips, on the side of caution. according to the manual, after the 1 is displayed, each segment of the led display signifies a different condition. it should the the lower horizontal for OK , and the upper is mute on or off. BGM mode is the bottom right segment, and tape mode is the top right. all the dip are to the left, which should mean BGM and tape are off. i am at a loss .

I'm going have to talk with Germany on this one. I don't have a parts
breakdown for the K-99 amp and as such can't price out the CPU chip,
which may well be the problem. It appears to be a PIC of some sort...

I will see if there is a troubleshooting guide for the amp that I can
provide you besides the basic one found on my website.

One thing you could check is with a logic probe or digital voltmeter
verify that pin #11 of the ST6225 (CPU) is high (/Reset). If low then
the CPU is forced into Reset and nothing will happen - check related
capacitor, diode, etc.

Check the voltages in the amp - they are listed on page 14.

"Old pinballers never die, they just flip out."

thanks. i'll let you know.

it will be a couple of days before i can get back to the juke, but i called my friend and had him observe it . when it first powers up, it flashes all 7 segments once, then goes to the numeral 1. im not sure if i had forgotten, or it was late at nite and i spaced out, but he told me the 1 in the amp display is flashing the 1. he turned it off, then on a few times, and it is always a flashing 1. is that any kind of clue? again, i apologize if it was flashing and it didnt remember it was. it was pretty late at night when he asked me to look at it.

thanks

Just wondering if you ever found out the cause of flashing 1 on k99?
I have same problem and mute led stays on.
It flashes a 1 with all connections except power disconnected from the amp.
Can't find the solution to this problem. Replaced a defective quad NAND IC (61C1) in the mute circuit but still flashes a 1.
