Default MELCO emc6 advice

Hello all,

I have a Melco emc6. about a year ago it developed a problem with the keys not responding on the keyboard after the machine stars running. I used to be able to get past this by wiggling one of the keys but as time went on it got worse.

Finally I started looking for places online to send in for repair. I found "Industrial Repair Service". They advertise a nice warranty and claim to have repaired this particular unit in the past and they have a location in my state.

After a few emails about the keyboard and my problem I sent in the keyboard to Arizona (I live in cali and they have a cali repair hub but was told to send it there). There was a hiccup for them finding my package (which was never explained to me) but after they found it they said they replaced all the buttons and tested it and sent it back.

When I got it back nothing worked. There's an LCD screen on the keyboard that worked fine before I sent it in and now it doesn't. I called it in and sent it back. This time they outright replaced the screen (which I didn't think was broken) and claimed to test it and sent it back. Still nothing works. I haven't moved the machine or turned it on when the keyboard is gone. It fires up fine and is detected by the Melco software on the PC but the LCD on the control is blank and necessary for operations.

I asked Industrial Repair Services if they ever got anything to display on the screen and they said all they did was verify signal has been sent to it and without the signal from the embroidery machine they cant get anything to display. So that means this unit is not actually tested. I am told I will be receiving a refund but this still leaves me with a machine that doesn't work.

I read about other people having problems with the power supply but theirs were described as an @ sign popping up on the screen and mine does nothing. I used a ac volt meter to see if the screen is getting any voltage the first time I got it back and now and both times on some pins it would get between 3-6v ac. I don't know what the values are supposed to be but it seems to be getting some power. I tried the dimmer and I get nothing when I turn it either direction.

Any advice would be great, thanks.

Electronics are my weakness, unfortunately. I've had better luck avoiding "embroidery machine specialists" like the plague and trying to find general industrial electronics repair shops instead. Look for ones that repair manufacturing machines of all types. In my experience, "embroidery specialists" are rarely able to answer my questions, if they can even be bothered, while industrial electronics guys are hard to shut up once I get them talking (annoying, but a good sign).

My local shop repaired my black box, my DC motor encoder, and a bunch of other components with which, given my level of expertise, I have no business tinkering.

That’s exactly what I did. In my post I said I went with “industrial repair service”. They repair all sorts of industrial electronics (or claim to) and they messed it up worse than it was before.

Well, that's my oversight, then. There are good repairmen out there — I hope you're able to find one.

This led me to believe that the company might have claimed an embroidery specialty. I just wasn't sure, so I threw what advice I could your way. I'm sorry I don't have any further expertise to share, but I''m going to follow this thread so I can learn from any solution you find.

Update:
I bought a refurbished keyboard from Embroidery systems in Canada and it works. Looks like Industrial Repair service broke my keyboard and admitted they don’t have the equipment to fully test the unit AFTER claiming it was tested.

I hope this helps anyone in the future. Do not use Industrial Repair Service. They broke my equipment and tried to say they couldn’t have but it was functioning before I sent it in. When it was returned they said it was tested and it was not. They later conceded that they need a signal from the embroidery machine to fully test the lcd and they don’t have one.

Only reason I didn’t go with Embroidery Systems is because it’s in Canada and I assumed it would take longer but they ship faster than IRS and they have the machines to make sure everything works. I am kicking myself for not using them first.
