Electronic Keyboard: Teclas não saem som, caixa de som com mal contato

Sat, 06 May 2023 11:05:00 -0700

Eu tenho um yamaha psr-185 que ficou muito tempo guardado, quando eu o ligo na tomada e pressiono suas teclas elas não funcionam porém quando eu toco de leve na superfície ao lado da caixa de som sai um barulho muito alto, minha suspeita é que a caixa de som está com mal contato apesar de ambas apresentarem o mesmo problema

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?

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

Epiphone SG Guitar: How do I prevent my guitar's input jack from loosening?

Fri, 10 Apr 2026 03:47:33 -0700

The input jack on my Epiphone SG electric guitar keeps loosening after several hours of (nonconsecutive) play. I don't want to strip the backing plate screws by removing the plate to tighten the jack once a week! The jack on this model is on the front face of the guitar.

Other than looping the cable through the guitar's strap to prevent excess pressure on the jack, what's a good solution to this problem?

Possible ideas I've thought of include loc-tite (which I'd rather avoid) and replacing the jack's washers with larger diameter ones to prevent the tension from compressing the wood.

Teenage Engineering OP-1: Why won't audio come from the right channel of my OP-1?

Tue, 17 Mar 2026 18:42:12 -0700

I have made sure that all the tracks are panned towards the center, but no audio comes from the right channel. If it is plugged into speakers or headphones and panned to the center, audio only comes from the left side. If it is panned to the right no audio come out. I was curious as to if there is something I am missing or if this is a hardware problem that requires repairs/parts. Thanks!
