I cannot enter test mode. Holding the L and R buttons, and then pushing the power switch, don’t do anything. The number display remains at 00 and pushing + doesn’t change a thing. 

What do you mean by the group’s photo .test MX?

Where is the keyboard’s thermostat?  There was no abnormal movement when this error occurred. The player simply stopped playing music all of a sudden. 

I don’t know if the issue I have is due to failed capacitors (all of them look okay; no bulge), failed fuses (two fuses are they’re in tact), or something else. Again, the system turns on, but the LCD is nonsensical and pressing buttons doesn’t do anything.
