Question about Yamaha Audio Players & Recorders
To my knowledge most LCD display of this type would (at power up) indicate a systems check (all display shown) and revert to default display soon as diagnostics are finished. Since you have done a reset (revert to factory defaults) and yet no display is indicative of a major problem in the logic circuitry. I would discount any power supply issue since as you posted "...display lights..." except perhaps the +5VDC rail (which supplies the logic circuitry). The are some instances of other versions of a possibly failed memory battery.
Since diagnosis and repairs of this nature would require familiarity with electronic circuitry and components, use of a DVM and possibly a soldering iron and access to a service manual or at the very least a schematic diagram with voltage readings, it may be to your advantage to seek the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
