Iirc Update so far. Cleaned the board first pass. Jumped where tracks are bad. Needs some coating to tidy up and another pass with vinegar to get the rest of the bluer corrosion off. Especially under the cpu legs.

Hi can anyone help has anyone got the flash file for empire games buck shot £70 jackpot mpu5 please luckily pic chip is fine but card battery damaged have soured a card just need file many thanks in advance

Any help appreciated regarding sound problem

Would anyone be able to help locate the problem on only some of the sound ? It plays OK and clear on most but as the game progresses to next stage of winning it goes distorted or missing just on that bit

Iirc I have removed boards and battery. There is some corrosion. From the leaky unit. I have used white vinegar to neutralise then ipa to clean. Next job is to use multeyer to check for breaks

Maygay M2 is the Quiz game roms are dumped but the questions are missing IIRC

Hi, there is more than likely battery leakage on one if those boards. Do you have a picture of the front of the machine? as wondering what it is? a quiz or fruit machine?

welcome, which machine did you get?

With the coin mech coils it's more than likely the BC337 driver transistors. If there's any green legs I swap them all out (10 off). The triacs do fail of course but it's more often the transistors. Stuck lamps is usually the PNP transistor T29 for some reason it fails more often than any of the others, no idea why? Check out the diagram so you know which line of lamps are the culprit. Twitchy reel, if I suspect a bad transistor I usually change all four, saves on repeat faults.

Not a chance Bob, it was my goose chase, managed a machine test, twitchy reel B, will check the transistors, Had a lamp issue prior to it failing I changed the suspect transistor to one from an mpu4 BDX something I think, but I see some 4 lamps brightly stuck on, Also the coin mech colis are not energising so still some work to do Thanks Ronnie

Phew, I was getting worried I'd lost my touch for a bit.

Well blow me down Bob! That was the issue! replaced everything in that corner inc the big diodes and it now clear the resetting screen, you would have probably changed all that before testing it, but thanks very much again, just need to machine test it now. Thanks Ronnie

Hello guys. So after much work with PCs, I now have my first coin ops. I have a screen game called Risk by MayGay. So far. Power supply works. 5v and 12v to IO board. CRT lights up white, so no video signal. If any of you have any k owledge of this particular game, I would be grateful

No not replaced any of those! Will do that next Thanks Ronnie

Hello! I've just collected my first fruit machine and looking forward to getting started maintaining and playing it. ihw123

Thanks Bob I will need to check on that and get back to you

Hmm, I don't have an MPU3 to hand to confirm the input to the chip but I'm wondering if the voltage level is too high? Did you change all the components on the input (R83, 84, 85, C39 and D43)

Hard to see from the pic...but the solder pads look fresh and unsoldered

Cheers I will check but sure it’s ok

The soldering on the ic on the right of ic20 looks like it's been forgotten

Hi and welcome, i have emailed you as well just in case you are still having problems. As the saying goes "been there done that"

Your English is better than my French welcome to the site hope the fix works

I’m probably missing something you would spot right away ! Here is the trace into pin23 it looks odd in the pic but it’s peaks and troughs to the eye, but it differs slightly compared to a working board

Can you look at this thread it might help. If not the answer was to scroll to the bottom of the screen and change your theme. If that doesn't work someone else has suggested sending you a PM so I'll do that as well. Hope it works. Bon chance Bob
