Tcrusenberry Posted September 7, 2016 Share Posted September 7, 2016 Any LED button experts here? I bought a new mame machine and the LED buttons do not light up. There is power and the buttons work just no lights... Any ideas? Link to comment Share on other sites More sharing options...
progets Posted September 7, 2016 Share Posted September 7, 2016 1. are you sure the positive and negative aren't reversed? (most can only be wired one way) 2. are you sure you have the right voltage and amperage powering them? 3. are you sure there the bulbs are inserted and making contact? 4. is it possible they were connected improperly and the bulbs got burnt out? 5. are you sure the buttons are being powered? (they usually use a different power connection or LED controller than the micro switches) More details about you setup or pictures would be helpful.

The led buttons worked before and the machine was put in storage. After unpacking the machine they just stopped working 1. yes they are wired correctly 2.correct voltage 3. they should be but I am double checking this 4.I don't think so 5. They have voltage and were tested This is a good check list I will double check. If anything else comes to mind I am all ears and thank you!

progets Posted September 9, 2016 Share Posted September 9, 2016 Are you sure you aren't missing a second AC plug that powers only the LEDs? This would be pretty typical in a lot of setups. If you follow the wires that aren't connected to a micro switch on a button where do they go? Then what connections are being made from that controller or power supply?

I included a couple of pics maybe you see something I don't The inside cab pic is the wire but it is not plugged in. Link to comment Share on other sites More sharing options...
progets Posted September 9, 2016 Share Posted September 9, 2016 Have you tried connecting the two wires to the power supply/transformer? Link to comment Share on other sites More sharing options...
Tcrusenberry Posted September 9, 2016 Author Share Posted September 9, 2016 yes and I get nothing. voltage is working so something is not working as intended Link to comment Share on other sites More sharing options...
progets Posted September 9, 2016 Share Posted September 9, 2016 That is a very simple circuit. There are only two wires and positive and a negative (ground). The positive wire gets connected to the positive on the transformer and then daisy chains to each positive connection on the buttons. The negative gets wired to the negative on the transformer and then daisy chains to each negative connection on the buttons. If this was once working like you mention there are really only three things that can be wrong. 1. the transformer is bad 2. there is break in one of the wires 3. all the bulbs are burnt out Try testing for voltage at the last button the daisy chain connects to. If there is no voltage there then there is a break in one of the wires. Make sure you're testing the wires that go to the lights and not the micro switches since they are powered separately by your encoder. You can use a 9 volt battery and a couple of short wires to connect to just one button's LED and see if it lights up. You can also remove a bulb and hold it up to a light to see if the filament is broken. Where do the other two wires that are connected to the transformer go? To the light for the marquee?

Tcrusenberry Posted September 9, 2016 Author Share Posted September 9, 2016 yes the other 2 wires go to the marque (which works) maybe all the bulbs burnt out? i will try your suggested method im guessing the more logical problem is a break somewhere thanks for the help. I think I can pinpoint it now and come up with a solution Link to comment Share on other sites More sharing options...
Tcrusenberry Posted September 10, 2016 Author Share Posted September 10, 2016 i plugged the led back in and let it boot up. Nothing happened on boot then while i was gaming the 2player start button lit up for about 3-4 mins then went off...... so odd Link to comment Share on other sites More sharing options...
Tcrusenberry Posted September 19, 2016 Author Share Posted September 19, 2016 Ok it has been awhile but I have narrowed my problem down to a couple of things. Is it possible all of my lights burnt out minus 1 (this light kinda flickers and is not as bright as it should be)? I have the correct voltage going to every button and no lights. I tested them with a 9V battery and they did not light up either. I have ordered some new led lights and will be replacing them and see if it is the lights. Anything else I could be missing? thanks Link to comment Share on other sites More sharing options...
progets Posted September 20, 2016 Share Posted September 20, 2016 Flickering light is what happens before the bulb goes out. The fact that it flickers is telling you it's getting power at least sometimes. Change the flickering bulb and see what happens from there.

mikekim Posted September 24, 2016 Share Posted September 24, 2016 with problem solving its better to start off small. just plug in one bulb to your psu and see if that works and go from there adding a couple at a time. Link to comment Share on other sites More sharing options...
jojonl Posted September 24, 2016 Share Posted September 24, 2016 I'm new when it comes to LEDbuttons but not new to LED technology. Please make sure that Mean Well driver deliveres the right voltage for the LEDs and also has enough power (wattage) to power them all at once.Maybe they're 12v so your 9v battery only lit them very dimm or not at all even.And just meter the output of the Mean Well to make sure.

Tcrusenberry Posted October 4, 2016 Author Share Posted October 4, 2016 Well problem solved. Apparently during storage every led bulb burnt out (which is extremely rare)..... replaced the bulbs and works nicely. Only problem now is my trackball was lighted and to replace that LED I think I need to replace the entire trackball............ Link to comment Share on other sites More sharing options...
progets Posted October 4, 2016 Share Posted October 4, 2016 I'm glad you got it fixed. I agree that it's very unusual that all the bulbs would go bad just from being in storage. I doubt that you need to change the trackball to fix the LED light in it. It should be serviceable. Link to comment Share on other sites More sharing options...
