Thank you, have a GOODTIME....

@@GOODTIMEStech hello again, I was wondering to ask you. I do work with this kind of keyboards often, and I found two PA 50 SD keyboards do have same issue. both of these keyboards do have very low sound. what I did for one of those keyboard is changing the mother board. then it started to work fine. the low sound issue was not there anymore. now my problem is changing motherboard is costly. if I can do simple component changing like you did it will be way cheaper. But then I argue like this., if it was a amplifier related problem how It stated to work fine when i changed the mother board. please help me to solve this issue

I also have similar problem. Is your problem solved? If solved, where did you repair?

C114

Tengo el mismo problema ..quisiera saber cómo lo resolvió.. se lo hagradeceria

Hey Daniel, i have the same problem with my Roland E-86. Did you solve the problem?

Hi, It's really very difficult to say without checking the device personally but basic thing is to reset the device and if that doesn't work, then check the output voltage from adapter (integrated but independent,15V 3A) when there is no sound o/p. Check whether the mainboard is overheating or AC power adapter is overheating after 30min (as you mentioned). If mainboard is overheating then need to check which component is overheating and why. If power supply is faulty then it needs to be repaired or replaced. Hope this will be helpful. Thank you, have a GOODTIME....

@@GOODTIMEStech thank you for such wide answer. I contact couple of services here in my state and they told me that it can't be fixed they told me that there is processor making problems in the main board and there is no parts for to replace. Am so sad to har that. I have an pa500 that work just fine but it's an limited option... have a nice day or night 🙂

​@@GOODTIMEStechhi again i find an pa80 it work fine but afther some time the sound is going lower almost dissapier and afther punching with hand it goes to the normal. What it can be maybu some contacts loosing connection or what? Thanks in advance

Hi, I replaced C114 , if this doesn't solve then replace BC548 and check. Thank you, have a GOODTIME.

Thank you for watching and valuable comment. Have a GOODTIME.

Hi, it is not much complicated but if you are trying to disassemble for first time, it may appear a bit difficult, the problem might be the rubber pad of that one particular faulty key might be broken or it is dusty or there might be dry solder at the cable connector. if you can disassemble that particular key set with that faulty key, it can be fixed. See if the video in the link below can be helpful, but it is of a different make and model of keyboard. kzfaq.info/get/bejne/iL9lich8zcivnY0.html Thank you, have a GOODTIME....

@@GOODTIMEStechthank you sir! I have pa80 and i saw that this one key sometimes work sometimes not it depends whow i push the key if i push the key in an angle it work if i push straight from the top it wont work. So may be the rubber. I wach the vid on yt where dude put graphite from simple pencil on the mark and just scrach and clean the rubber an it work.

@@GOODTIMEStech i can record my 'work' and post here on yt on my channel if you any interested to see how i fix that or at least try to fix 🙂

@@Imalogike yes, please share the link, it might be helpful. Thank you, have a GOODTIME....

@@GOODTIMEStech i will,have a good time you too. Tell me where are you my friend? I Am from Serbia 🙂🇷🇸

Hi, Does this happen even while using headphones or output to amps ?

GOODTIMES tech ™ no..both right and left sides are working while using headphone..problem is with keyboard built in speaker

Sir, I expect your valuable reply soon. Thank you.

Sorry for delay in reply as i am not getting notification of comments replied. in the video i have replaced the transistor and mentioned about a diode beside the transistor , isolate that diode and check, also download the datasheet of output amplifier IC and check for voltages of IC legs match datasheet details, if not replace the IC and check.

Hola hermano pudiste solucionar?

Where you from

Did you ever get a reply?

Hi, first of all try removing all connectors and reconnect , clean them if any corrosion, if this doesn't solve then check for faulty capacitors and replace , some times noise is generated if ground connection from one PCB to Other has failed so reconnecting all connectors firmly is necessary. Thank you. Have a GOODTIME.

Hi, sorry for late reply, i will check and let you know if i get it. Thank you, have a GOODTIME...

@@GOODTIMEStech Hi, I wish if you got it

I didn't understand language sir ,can you please translate in English ? Thank you. Have a GOODTIME.

Hello sir wat is second transistor model number

c114

If you have technical knowledge please check for all voltages , you can check the voltages at +ve -ve terminals of filter capacitors.

@@GOODTIMEStech cual es el transitor que cambio?

I didn't understand sir, if its English it will be helpful. Thank you for watching. Have a GOODTIME.

@@GOODTIMEStech aq onde moro não achei esse transistor qual posso colocar no lugar?

Le cambiaste el transistor al pa50?

Que falla tenía tu pa50?

GRACIAS A DIOS YA LOCALICE LA FALLA. ERA DE LA TARJETA DE SALIDAS LOS TRANSISTORES.

@@ministeriodealabanzareydeg5853 me podrías decir que transistores eran y cuál es la tarjeta , creo que usa dos tarjetas, cuál de las es la que reparaste? Gracias

Es la tarjeta que va junto a las salidas ahí va los componentes y se an quemado 2 y paso xq el cable de salida estuvo chocando contra el otro y quemó los TRANCITORES. No tengo a la mano pero voy a sacar el número de modelo de los mismos.👍

Its BC558. Thank you for watching the video, have a GOODTIME

Okay...thanx

Its BC558, sorry for bad audio. Thank you Have a GOODTIME.

GOODTIMES tech ™ thanks ..from indonesia dangdut music

Power suply problem ...can you help me?

I stay in INDIA sir, very difficult to guide to repair powersupply from here. i feel you can get it repaired from person who can fix SMPS powersupplies in your city. Thank you sir. Have a GOODTIME.

GOODTIMES tech ™ hlooo

Thank you for watching, have a GOODTIME.

Hope you tried resetting the system. Thank you for watching, have a GOODTIME.

@@GOODTIMEStech hi where I can buy this transistor?

Yes sir, Thank you for watching, have a GOODTIME.
