Hi,
Well got the new jukebox home. Works great but the lights at the top by the moving cd's and at the bottom in the strips in front of the speakers do not work. Is there a seperate fuse for these are could they just all be burnt out? The other lights all work. I have the manual on CD but have not found anything on the lights yet.

Thank you,
Joe
 
Most likely they are burned out. They are miniature lamp type # 73 which you can buy at any auto parts store if you need them right now. Otherwise you can buy them through the usual amusement/jukebox parts suppliers.

These bulbs are wired in series parallel in the circuit. If one burns out, the one next to it will go out. These bulbs have very delicate filaments when they age and burn out easily from vibration as they get older. It has been my experience working on these jukeboxes that when one #73 bulb burns out, replace all of them or else you'll just be tearing things apart all over again 5 minutes later when another one burns out.

If after replacing all the # 73 lamps they still don't light up, there are two possibilties:

1) one or more of the brass 'prongs' on the lamp socket are not making contact with the lamp pc board. This is very common and the prongs just need to be bent upward some more. Sometimes the socket itself goes bad and the socket must be replaced. These must be ordered from a Rowe jukebox distributor.

2) In the amplifier compartment is a small terminal strip with a resistor mounted to it. This is a current limiting/dropping resistor to the # 73 lamp circuit. If the resistor goes open, there will be no voltage going to the lamps. With as many jukes as i've worked on, I've only seen this resistor go bad once.

Hi Ken,
Well, I checked the lamps and they are good. What voltage should I be seeing at the lamp connector? Also, I found the terminal stip and also need to know what voltage I should be seeing there. Almost seems like no power? Are there any fuses?
Thank you,
Joe
 
The lamps are run by 28 volts AC from the power supply assembly through that resistor in the amplifier compartment.

On the power supply output connector pins 7, 8, and 9 are ground. Pins 5 and 6 are 28 volts AC. From the power supply the power goes to the limiting resistor then to the # 73 "animation" lighting circuit. On page 8-34 of your manual, that resistor is shown. However, now value is stated for the resistor. You'll have to read the printing on the resistor itself and write it in the manual. If the resistor is open, there will be no power to the animation lights. It's been along time since I encountered that one jukebox with the bad resistor. I don't remember the resistance value, but I think it was a 5 watt rating.
 
Hi Ken,
Last night I checked and did not find any voltage at that terminal strip.
(I checked both sides).If the power supply is not providing the 28v what else would not work? The animation motor does work and it seems that only the lights do not
work. One other think I noticed that may not be related is when I plug
the jukebox in the amp powers up (hear a pop through the speakers) but
the switch is not on in the back. When I turn the switch on everything else
powers up (except those #73 lights).
Also, Have you ever seen were the power supply was not working on the 28v side? I do see 3 red LED's that are on on the power supply.

Cold solder joints on the power supply board connector header pins is very common on these jukes.

Also, as I mentioned, check the resistance of that resistor to see if it is good or bad.

As to the amplifier thump, Rowe ships the juke with the amplifier power cord plugged into the "amplifier" socket on the power supply. That socket is live all the time regardless of whether the power switch is on or off. I always plug the amplifier into the "service" socket instead. That outlet is controlled by the power switch.

Just was looking on ebay and saw a control like mine but mine does not have that box/cover at the top with the spacers behind it. Is that the problem? Is that just a cover or is there some parts in there? I see the hole on mine but that part is not on it. Here is a pic of the one I saw.

You must have an updated power supply board. That also means you probably have an updated CD player like a CDPRO installed.

The picture you posted is of the old style power supply.
 
Hi Ken,
Yes, it has been updated with the pro player. That explains the diff. Will be checking voltages and looking for some bad connections tonight or tomorrow night.

One more question. All 3 LED's are lit on the power supply board. So that means it is working? I noticed the board has a couple of fuses on it. Are they related to the 28volts and if one was burned out would all 3 LED's still be lit?

Thank you,
Joe

Hi Ken,
Well, I checked the voltage again (this time checking for ac voltage (woops)) and there is power to the lights. So now I am stumped. I pulled one of the bulbs out and it checked out ok. I was not able to get the light sockets out? I turned them to the right and left, like the car ones and the sockets hardly move. Don't want to break them. So I am now thinking the sockets and maybe some of the bulbs are the problem. What is the secret to getting those sockets out of the board? Yes, I am having fun.

The light sockets only turn about an eighth of a turn. I think clockwise locks them and counterclockwise unlocks them. Yes the sockets are just like a car dashboard type. They fit very tight. I use common slip joint pliers to grip the socket and carefully turn it. Turn slowly and carefully as the sockets are delicate from age.
 
Thank Ken. Just in case I mess some up I ordered new lights and sockets today. Another quick question. I looked in the manual but don't see anything about this. Is there a way to adjust the brightness on the display? I can see mine but when it is bright in the room it is hard to see.

Thank you,
Joe
 
Brightness of the display is not adjustable. Be sure the face of the display itself is clean along with both sides of the glass window in the juke. You can unbolt the display board assembly from the jukebox and slip it out of the jukebox after unplugging the connectors. Be careful as the glass window in front of the board is "loose" like the warning stickers say.
 
Hi Ken,
I have read somewhere that the #73 bulbs only come on when a cd is playing. Is that true or should they always be on when the box is powered up? Once I get them working I promise not to ask anymore light bulb questions.

Thank you,
Joe
 
Hi Ken,
Got the new bulbs today and put them in. They still did not light. I checked and I had power to the lights. I then hooked up a single light to the connector and still nothing. Had a beer and then tried jumping the terminal block that has the resistor on it. THEY LIGHTED UP!
So, my question is, is that too much power or with the upgrades that were done for the proplayer with the new power board is the resistor not required? I have an old voltage tester and cannot tell the exact volts but it looks like about 24v. Is the wattage the problem?
Joe
 
Hi Ken,
Just want to post an update. Took the resistor to work and they checked it and found the ohms were way too high. So the part was bad. Got a new one and put it in last night and now all the lights work. Thank you very much for your help trouble shooting this.
