Emu XL-7 & MP-7 User's Group

Sorry that you're having this problem, I've had sort of the same problems but luckily never needed to send the units in. I used an eraser "carefully" to clean the connectors on the ROM and that worked one time. Sometimes the connectors just get old and that's it. The main boards are $192.99 but If someone is good with the soldering gun? Who knows.

Again Good Luck, and welcome to the group.

Thanks. I already did try the PX-7 ROM by itself and it was not detected. I run the diagnostics and there too all the ROM were not detected. I did a reset as you suggested but the ROMs were still not detected. There is a pretty good music/audio repair shop near where I live in Virginia (Music Technology ) and the guy says he fixes them and will take a look at it.  I am hoping I can fix it myself.  If not, I will send it in.

When I go to presets, I get a "not installed" message or Instrument ROM: ?????? and under that "not installed. I do know they are installed. To be sure, I opened it up and made sure they were seated properly. I even took them out and moved them around. Nothing helped. The message was the same. The ROMs are properly installed.
