Unfortunately Adam's machine has ended up at my place with more issues. Most I can or have sorted out but the deathstar door has died again. At first it seemed to be a connector issue under the playfield. The door started working without fault after a bit of a tinker. That lasted a week or two but the door is now DEAD. I have re-pinned the connector, re-flowed the solder joints on the relay board as well as replacing the diode on the relay board.
There is a small cap on the two yellow wires going directly to the motor. Does anyone know whether this cap is essential to the operation of the motor i.e. would replacing it possibly solve the problem?
I would really like to get this machine up and running 100% for Adam. He paid top dollar for a machine that did and still does have some significant issues. His first machine is turning out to be a bit of a nightmare for him. At the moment I am leaning towards a dead motor for the deathstar door. Can anyone think of anything else I can try or test to come up with a permanent fix?
I re-built the power supply board today to hopefully resolve the problem of random resets. I am also trying to sort out an intermittent sound problem where the sound drops out every now and again. Also looks like the machine is going to need a new DMD as well due to out-gassing.
I think the motor will still work without the capacitor. Is there any voltage going to the motor during test ?
Sound drop outs - How often does this happen ? Can you swap the speaker as a test ?
I don;t like these multiple issues on a machine, especially when sold to a new hobbyist. If this was bought from a dealer I'd be looking at claiming warranty. Certainly was not sold as working ?
Nino, that is the saddest part of all this. The machine was sold as a fully working machine to my understanding. The seller has refused to speak to the buyer any more and has not replied to my email that I sent him a few days ago. Mate in all honesty you would cringe if you saw some of the things that were not addressed on this machine. If it had of been sold as a project then fair enough but it wasn't and a new guy to the hobby has been taken for a ride it would seem.
Sound issues are sorted - loose grounding wire from the speaker to the backbox. I had to put a new display in it as well, the one supplied with the machine was in the early to mid stages of outgassing.
As it stands at the moment, it is just the deathstar door that is not working. I have tried swapping relay boards without success and also re-flowed the joints on the relay board for the door. I am not sure if there is anything on a board that controls that door only as everything else seems to be working OK. It is leading me to think the motor is dead. I put the DMM on the connector that attaches to the motor and from memory it had 29V there.
Thanks......
