    I have a Yamaha PSR-E443 keyboard that won't turned on. If i pressed the power button, the display will flash in second and shuts down. I have tried using another power supply adapter yet the same problem. I also tried using the battery but it still doesn't solve the problem. Please help me. Thank you in advance...

    Check for sticky buttons or keys. It may be one of them is stuck in the on position causing it to fail the power on self test.

    Otherwise it may be a problem with an internal latch circuit. Depending on the complexity of the design and what sort of chipset they're using it may be more than a simple DIY fix.

    I don't try to do any maintenance myself, but if your PSR-E443 is no longer under warranty and you think you can handle trying to fix it yourself-- or if you have a friend or acquaintance who you trust to try to fix it-- then you might find the Service Manual to be helpful. You can download the PDF file from ElektroTanya:

    Otherwise, the best thing to do would be to have a qualified and Yamaha-certified service technician look at it.

    It's warranty period is over. So, I'll try all your suggestions. Hoping it will work. Thank you very much...
