Hello everybody!

I have Yamaha YPT-220 / PSR-E223. It powers on, respond to keys (i can see on the display that the proper keys are pressed). Unfortunately, there is no sound at all. I checked on headphones, speakers - nothing, no humming etc. Dead silent.

I read on one of the forums that replacing BA5417 might help, but after the replacement everything is still the same - no sound.
What could cause the problem? I checked and found out that two capacitors are shortened... I don't think they should be, but I am not sure (I am not a proffesional electronic technician, but I know how to replace resistors, capacitors, IC's etc).

Here is the video of the two elements that I found out are shortened...



What are your suggestions? What could help and what else should I check?

Thank you.
