I got a psr E433 it is missing some parts on the analogue board, 1. The switching transistor 2. The regulator on the heat sink together with audio amp IC Can you please help me with the part numbers for those 2?
@@thoppzy23 Thank you I replaced with TIP117, and tested all components around, When I connect power supply and bridge CN203, I get power (about 12V) but it powers down as soon as I unbridge. Is this correct?
@@thoppzy23 I understand sir... That is the best component I could find. Please help me understand. Is power switching completely controlled by the analogue board.. PSR e433
Hi sir, I have a Yamaha keyboard PSR E423. The volume reduces everytime I didn't use it for a while. As of now the maximum volume can not be heard at 2-3 feet away. But it worked well with the 1/4inch cable to speaker connections. Without external speakers I can play it comfortable because I struggled to hear what I was playing. Please I need your professional advice on this issues. Thank till I hear from you.
I'll suggest you check the capacitance and ESR of the capacitors around the DAC around the digital motherboard. Most especially the ones connected to L & R output pins of that IC.
My piano PSR e333 only powers on when when only the button has been pressed forever or else you apply saliva then it will remain turned on until the saliva is dried up completely...how do I solve that
Hello dear I'm from Srilanka, my Ymaha E443 turns on while I connect the power adapter without the power button pressed. Sometimes it takes several minutes to function the keys also. Can you kindly give me an advice ❤❤❤
The main reason why it's like that is that, the transistor B1342 or B1568 is faulty, try as much as possible to replace it with new one. The keyboard will respond to switch. Concerning taking more time to function, just restore it to factory settings by holding the last white key by your right hand (key C6) then switch on the keyboard or connect the adapter.
same problem with my keyboard Yamaha psr e443. Sometimes it boots but most of the time it hanged on YAMAHA display. I'm from the Philippines. And I think I'm miles away from your repair shop. Maybe you can help me troubleshoot with the digital motherboard? or do you have some manual that I can read on to know how to repair mine if you mind? Thank you in advance for you help sir.
@@thoppzy23 they use adaptor right polarity when switching power on the LCD no display then apear bluescreen the mother board is not working but power suppy its ok
@PeterMuchiri-ub6mm that shows that the conductive ink has faded (the resistance is now low) you can work switch with it. Chat me on WhatsApp 2347034481622
good job bro. 👍👍👍

Why not get the right components and fix them at once. I hope you know that bridging has its own effect?
