Electronic Keyboard: Teclas do piano funcionam após poucos minutos

Sun, 10 Jun 2018 20:31:14 -0700

Tenho um piano digital yamaha p 35. Esse instrumento tem apresentado um problema estranho. Desde dois meses atrás, o intervalo de teclas entre sol-dó da quinta oitava não funciona quando ligo o instrumento e volta a funcionar após alguns minutos ligado. Ou ainda, se eu deixo o piano desligado por uns dias, as teclas voltam a funcionar.

Eu abri o piano e troquei as borrachas de contato e o cabo flat. Fiz a limpeza, mas o problema continua.

Alguém já passou por esse problema ou faz ideia do que pode ser?

Some buttons (main, tempo, fx) are mushy/hard to press than others on a brand new unit with v2 update installed on it. Is there a fix to this? How easy is it?

Electronic Keyboard: Yamaha PSR E253 has a button that keeps pressing on its own

Tue, 02 Jun 2026 21:52:24 -0700

Hello, there is a button in my keyboard which is the minus button, it presses on its own causing the voice to change continuously/constantly. And another thing is that I can't press other buttons beside it if it does that thing. What do I need to do to fix this?

Casio keyboard: CDP S160 a few keys mysteriously triggering or stopping other keys

Sat, 30 May 2026 12:41:18 -0700

This repair is for a poor customer who's 15 year old lad is so desperate to get it fixed! Yes he confessed to spilling some gooey drink over it! - cleaned carefully first four octaves contacts and PCB board. re graphited the board in places. Cured a dozen keys, BUT C1 + F1# + E2 + C3 + G3# giving very mysterious triggers! ( and these notes well away from where the spillage occured). These five sometimes no sound, then sometimes they all work, BUT when they are all working , holding down C1 + F1# + E2 together - The C1 delays - then double triggered several times sometimes ( whilst all three are continuously held down!) When these 5 x keys decide to work, they all work fine when pressed individually !! How mad is that ??

I know rubber contacts must be okay, swapped them to working parts of keyboard - and the working parts still no problem. Examined all connectors - very few anyway,

motherboard no visual signs of damage or corrosion etc.

Can only think the channels from some keys are interfering with others (short circuit?).

Not knowing how the send signals from each note are clustered together - so hard to prove any short or crossover going on.

. I see some questions here others have had similar problems, - and as yet unresolved?

teenage engineering EP–133 K.O. II: Need to replace the Fader and an encoder knob, need parts?

Fri, 01 May 2026 17:14:56 -0700

I bought one of these used, and the fader and the BPM encoder knob do not function correctly. I'd just replace both myself, but not sure what replacement parts to order. I've seen some sources say I just need a 45mm Type B 10k for the fader. I'm not sure about the encoder. Looking for answers.

teenage engineering EP–133 K.O. II: Input is not detected

Fri, 17 Apr 2026 04:12:14 -0700

Hi !

When I plug a 3.5mm jack cable in sample mode nothing happens.

The displays stays in MIC instead of switching to LR. I assume this is a hardware problem but I'm not sure about it. Is there any way to fix the stereo jack 3.5mm input ?

Thank's

Alain

Guitar: Humbucker selector switch problem

Tue, 24 Feb 2026 08:35:35 -0700

I am stumped! I just acquired a 25 year old Guild X-150D. It is great but I now have a problem. It has 2 humbuckers, 2 volume and 2 tone pots. When I select either pickup it works fine. When I select BOTH pickups (switch in centre position) only the bridge pickup plays. I have pulled out the switch, examined it and tested it with an ohmmeter. It tests fine on the meter. Both pickups connected. Any ideas?????
