I have an NAD 522 cd player with a dead display. These things have an LCD display backlit by three grain-of-wheat lamps, and it looks like one of them is burned out. Does anyone know anything about these? Any ideas about the right voltage/wattage for a replacement bulb? Thanks!
Leolabs said:Is it really a LCD??Look likes a VFD to me.
Maybe. Would a VFD need to be backlit?
Any idea about the lamps? If you've got one of these there that's working, would you mind measuring the voltage to the bulbs?

Do you show how to replace the bulbs with LEDs?
