YAMAHA PSR-S650 | Motherboard boot Problem | Dead Motherboard

[@danielbanares6580]

My friend, please help. My yamaha psr e433 rated 12vdc was supplied with 19vdc laptop power adapter, for a few months it was okay my brother could play it then one day the problem arose. When I press the power button the display is only all blue, then when I release the power button it turns off. Please help me what seems to be the problem?

Meu instrumento é igual a esse e está com esse mesmo defeito, será que troco esse componente que você trocou no seu? Poderia me informar a referência deste componente para que eu possa comprar por gentileza?

Make guided video on this model same problem ❤

[@pansiluhettiarachchi5384]

brother, I found this suddenly, my problem is as same in this video. what I face is when I plug in the keyboard to power and try to switch on the power button and after releasing it, it shows only a blue screen while pushing the power button, but not switching on the keyboard. After several attempts doing it by unplugging and plugging step by step, my problem can be solved and I can play. but whenever I start playing it another day again the problem comes and keeps disturbing me all the time like previously for some time. As you think what I should do brother and is this a vulnerable bad sign of my keyboard?. pls helm me, thanks

[@soundpro4654]

My friend. There is some moisture in your motherboard. Just take it out from your keyboard and clean it with thinner / CTC and you can use 99% alcohol. Use one of these with brush then dry it with hairdryer/ hot gun

Dear friend I have a same problem and model.. How to find problem

[@FabianSantamaria-q1g]

Hello, I have two Yamaha PSR-S710 and each one has a different problem, one does not recognize the USB memory, the USB serial port does not work, and the screen says "the connected USB device is not responsive. It does not recognize any USB memory or the serial port to connect it to the PC. The other PSR-S710, the screen turns on fine but the entire system is blocked, no key sounds, the buttons do not light up and are useless, only the screen looks fine, but the rest of the keyboard is blocked. Please remain attentive to any help and thank you very much.

Dear friend, my PSR e453 when I press the on button, display on but when the on button is relased it turns off. What is the problem?

[@soundpro4654]

Problem is in PNL-T board. Power supply card. Check the transistors TR101 ,TR102,TR103 Maybe it’s dry sold and u have to resold it and May be one of theses is faulty .check it and Replace it . Problem will be fix

[@kiranpapal]

Brother, how you start the motherboard without ON button attached?

[@soundpro4654]

Brother any circuit needs required voltages not a button . I just provide the voltages through external power supply

[@ldiazmdiaz]

Dear Friend I subscribe and like your KZbin videos. I am a Electronic tech and notice many cold solder on the Yamaha PSR-510 keyboard. Waiting for liquid flux to arrive from NorthridgeFix to re-solder many connections. Problems are the display is showing random numbers and lately sporadically the power is going off. I do have the service manual at hand. The display show random numbers at the first digit like 668 or 868 instead of 068, could it be the logic gate or display shorting. Thanks in advance....Help.

[@soundpro4654]

Thank you so much my friend . Tell me , 1 => Is the keyboard working properly other than display ? 2 => switches are working ? 3 => when you start the keyboard, is there any Error code showing on display?

[@jamesmutegi4685]

Hello, I have a psr s 650 with persistent backlight when power is plugged even without pressing the power on button. The motherboard is dead. How do I solve this problem?

[@soundpro4654]

Hello sir , check TR401 and TR402 on AM board . Also test the volt on JC2.0 or collector pin of TR402 (AM board ) There should be 0 volt when the keyboard is off and 16 Volt when you press power button ON

[@jamesmutegi4685]

Thank you for your directions. I will get back to you with the results

Always not the same solution for the same condition. In my case there was a short circuit on the board . In your case May be the other reason of motherboard not booting.

Video will not help anybody to repair its own keyboard. Most of the people around the world are looking for this kind of videos to get some tip on how to look for failed components and so. So, this is an advertising video useful for locals around your place.

[@soundpro4654]

Yes my friend. You are right. This videos for advertising. After some time I have realised that I have to make educational videos. Thank you for your advice. I will work on it

[@bepolite22]

@@soundpro4654 Is not only about educational, is also to help people and avoid musical instrument to go to the landfill. Once you start posting some helpful videos also will attract customers due to your goodwill. Here in USA is a shame to see how many musical instruments just go to the trash even working ones, mostly electronic keyboards and organs. I have a friend that works as piano teacher and restorer and I help him when get some electronics ones that doesn't work just to give them to his pupils to practice. So, thanks for take care of my comment.
