Hi all this is my first post but i have used this forum so far to fix many issues on a bellfruit snakes and ladders i bought not working.

The red led money display wasnt working because someone had plugged it in wrong but is ok now, ive had to fix the coin mech reset the stake/jackpot key and rewire the door switches so it enters play mode and now it works great all but some of the light not illuminating.

 

I have random bulbs out but around 40 in all on the gameboard and money lights mainly but they are dotted around all over the place as theres alot of bulbs in it.

I was going to buy bulbs however i tried working ones in the none working ones and they didnt work so i can eliminate the bulbs.i have removed and replaced the wires into the holders and doing so today made a working bulb not work even though it is registering the same voltage across the terminals as a working bulb.The wires are definately contacting correctly or i wouldnt get a voltage reading so im wondering if the small resistor or whatever it is inside the holder may be blown.

I dont think its the light board as i have unplugged the one that does the majority of the game board and others around it on the same curcuit that do light up go off when unplugged and then come back on.I also have working bulbs around all the none working ones sharing the same wiring so im guessing the wiring is ok.

The only thing i can think of is the holders but they seem so simple in construction its hard to imagine them failing but before i buy anything id like to pick the brains of the experienced people here, thanks in advance for any help, steve.

That many bulbs out won't be the holders. Well I'm very sure.. as all the machines I've worked on with many different holders haven't produced that kind of error.
Most likely the board has gone. It will be the data line travelling around the board not sending the correct signals.

[andrew96]

Yeah it won't be the holders, the bulbs are multiplexed which means you will find voltages across the holders and you won't be able to make head nor tail of that as non working to working voltages wont make much sense due to the fast strobing of selecting the lamps and a meter can't react fast enough!

 

what is the motherboard? I would bet you have blown transistors on it

Its a scorpion 5 board on it, relatively new apparently , not sure what the light board is, i just dont understand how lights are out next to working ones with the same wiring, theres 2 wires a purple and a yellow and they all come from the light board, but 2 plugs do take wires to the main board where im guessing the commands come from, i just dont understand how removing a holder and then rewiring it has made it not work, its a simple enough install, steep learning curve this is, how can i test for blown parts with a voltmeter will there be any signs on the board?

Forgot to mention whenever i have tested the bulbs and voltage i have made sure all lights were illuminated and not strobing, i was concious of that.

[NickYerPesos]

Scorpion 5 boards are so easy to destroy a line of bulbs. There will be two wires to each bulb.. I would expect one wire to be the same wire going through each of the bulbs that isn't working. Just taking the bulb holder out from the buttons and by touchING metal locking bar with the back of the button loom can destroy a scorpion 5 board.. so so easy

I also thought exactly the same but when ive looked i have working bulbs and none working bulbs on the same lines, thats the bit i dont understand if it were the board surely all the bulbs on that line would be out, but that does not seem to be the case, ill add a few pics tomorrow.

A few of the bulbs that are out have the line ending on them but in every case there are bulbs higher up the line working, could it still be the board if it has working lights on the same line?

[NickYerPesos]

Both wire lines yeh. Because one of the wires goes from bulb to bulb directly next to one another and the other wire seems to be all over the place going to bulbs all over glass (seemingly random)

[andrew96]

the lamps are done like this

 

 

 

BUT as Nick says each string goes all over the place, so one drive to one of the wires is out there will know a string of them out, but it will seem random!

 

scorp 5 is prone to these sort of troubles.

'know' should be 'now be'

 

sorry there is no edit button and I failed to notice that before posting

Makes sense i guess, i traced 1 wire back to the light board from its end which was a bulb that does light through another 6/7 that dont and then replaced it with a new wire direct to a failing bulb with no joy.

Only thing i dont understand is how can the final bulb light up at the end of the run and the bulbs on the same line before this dont.

 

The final bulb was 1 of 3 jackpot bulbs(other 2 have diff feeds) and then it skips £20 ,£15, and £12 which all light and goes to £10,£8,£6,£4 and i think £3 none of which light then passes through a snake which also dont light and then runs to the board.

 

My wires are purple and yellow and im assuming its the purple ones as they are far more random than the yellow.

If it is the board is it the scorp 5 or the light, is there a way i can test the board and maybe replace parts?

[andrew96]

It won't be the wire, it will be the drive transistors on the board, they blow

[orakal]

Anyway to locate and test them?, or even repair

[andrew96]

Use of a meter on diode check to test the transistors, but I have no board to look at so cant tell you more than that, I know there are surface mount transistors on board which don't make it easy to change them

[NickYerPesos]

I can get you a new one. They cost £30 to repair. Send me your old one and I'll send you a replacement.
