Mackie Tapco Th15a Thump Active Loudspeaker - Page 8 - Answered Questions & Fixed issues

It’s not likely you can. I’m repairing my board right now from the burnt crisp in one corner.

This could be many things. It is most likely noise from a defective chip in the unit. If sounds are normal except for the hiss, then test if the volume control reduces it. IF not, then problem is in the power amp section. If it does vary the loudness, then problem is likely between the D-A convertor and the volume control.

I would first try to isolate this by cooling selected parts with circuit cooler mist to see if you can find one that reduces the hiss when you cool it... Spray, then wait ten seconds before moving to the next on.

USUALLY semiconductors cause this, but rarely a bad resistor or cap can as well.

This will depend on what type of music you are playing, Where you are playing it, How loud it is being played and your personal preference. If you play in a small acoustic band in small venues simple foam or wax ear plugs could be enough. At the other extreme if your playing in a heavy metal band using huge amps and speakers you might need to look at using the heavy duty ear defender headphones with the digital 'active' noise cancelling built into them. If your working in a recording studio a good quality set of headphones would probably work as you have more control over the playback volume. Personal preference is mostly ear plugs versus headphone style ear defenders. Lastly is what they look like when your wearing them, If that actually bothers you.

keep looking try google maybe

It is a known issue https://www.justanswer.com/electronic-musical-instruments/4zmad-baldwin-pianovelle-rp150-digital-piano-i-ve.html https://www.google.com/search?q=Baldwin+RP150+no+sound ..

In a word, yes. Match the impedances.

Seems to be a little known South African keyboard. Some manuals but not yours. https://www.google.com/search?safe=off&rlz=1C1QJDB_enCA643CA644&sxsrf=ALeKk016am5sk2l8qqEQHKV8SQsEs8ZO_Q%3A1615762755259&ei=Q5VOYLqcD5CIggfDurroBQ&q=Sanchez+Ark15+manual ..

It is a physical keyboard, but you can download data from the Casio website. The manual is also in the link https://www.google.com/search?q=download+wk3500 ..

Last post will not let me put pictures for some reason so mine says Ibanez 61-12491

Contact Lowrey directly to inquire.

Just add some adhesive Velcro (hook and loop fastener) The industrial rated for 25 pound should be good for most players, 75 pound rated minimum for Jerry Lee Lewis type players.Set the stand at the height you want, put the hook tape on the stand leg top and then target the fuzzy strip to the piano. Be aware the pound rating is rated per square inch- so you will want to put a 10 or 12 inch strip of fuzzy on the piano, and 1 or 2 inch strips on the stand leg.

This is a common problem with Bugera. And, unfortunately they are made by Behringer who is known to have the worst customer service of all and do not follow through on their warranties.

Request the manual from Rogue.

It's here $16.15

I suggest checking to make sure those 2 units can actually use the same adapter and also check the polarity on both to see if they are the same. Most stompbox stuff usually has negative on the center of the socket, instead of positive like other devices. If I spend a little time I could find the manuals and find out for myself but, this was my logical "top of my mind" kind of advice. Those values (volts,mA, and polarity) must be known in order to help you further. I believe it will be 9v, a few 100 mA's, and negative in the center on both but, not sure.

Contact Clavinova directly to request the manual.

So I got a used one of these for free because it had the same issue.
I read about battery failure, so I opened up the piano and sure enough the battery had corroded. I also read that the battery is only necessary for the memory feature, which I don’t care too much about. I pulled out the board (super easy to do, no screws or anything, it just pops out) and took it a local electronics/tv repair guy. In about a half hour he took off the battery, fixed a bad trace on the board with a quick solder, and handed it back. $40.
Plugged it back in, bam works like a charm.
As long as there wasn’t too much damage from corrosion, a repair guy should easily be able to do what I described.
I hope this solves your (and anyone else’s) problem!
