Electronics Repair Questions? Ask an Electronics Technician
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Those pennies may have caused the problem. Or similar metal debris loose inside the keyboard may have caused it.
As they slid about, if they shorted out something, circuit damage could (I am sorry to say) have taken place.
I advise you to first of all, make quite sure there are no other pennies, paper-clips, loose fragments of anything of metal, etc. in the circuitry anywhere.
Then check all fuses esp. the main power fuse (unless the keyboard otherwise shows every sign of life).
After that... if no imprvement can be had... please tell me the age of your EP-97, and also your local zip code or town/city and state. And I will advise you further.
OK so far. Well done.
A schematic is not readily available. There may be a service manual, and I will seek one, or a source for one (hopefully free.)
Do you have electronics tools (i.e. soldering iron, volt meter, at minimum) ? and skills, I might also ask...
The audio amplifier is either disabled (possibly by a settings change?) or else is 'broken' - probably by those pennies getting across some components and frying something, and I really hope not.
To make sure it isn't just a (spontaneous?) settings change that is disabling audio:
First, check that the MIDI settings are Off. MIDI Out enabled, sometimes disables speaker audio.
Second, check that the headphone or earphone function is (or isn't?) producing sound.
There is a dubious source for a schematic, but it has no download link to the document you're seeking, just false links.
This site seems to list the EP-97, but it seems to lead nowhere:
OK, I am looking them up with that zip code information, and thanks for providing it... expect me to post again with results (hopefully!) within 20 minutes, or less, depending upon difficulty.
There are two in your zip code region in central California:
• Carry-in service on Roland and BOSS products
PO BOX 821ROCKLIN, CA 95677(916)(###) ###-####/strong>
• In-home service on eligible Roland home pianos
and also these farther away:
CAMPS ORGAN SERVICE
Roland Factory Service
2530 E Lindsay Privado Unit AOntario, CA 91761
MUSICIANS SERVICE CE
C A E SOUND
285 N AMPHLETT BLVDSAN MATEO, CA 94401(650)(###) ###-####/strong>
UNION GROVE MUSIC
or rather far to the south:
1034 E GRIFFITH WAYFRESNO, CA 93704(559)(###) ###-####/strong>
I hope that one of these can provide help. (If none can, let me know... there may be more help I can offer in that hopefully unlikely case.)
If this answers your question, please rate my answer. A five-star rating would be appreciated!
Thanks. And good luck with your Roland keyboard.
I hope that my listings did indeed include one shop that could - and did - help with the problem. If not, I have not done enough, Ginger.
But I'm glad to hear your praise for my assistance! Thanks.
