Has anyone seen old Sony audio equipment with a very dim LED backlight on the LCD front display? I want to know if this is a common problem before I start tearing apart this thing I got from the thrift shop #askfedi #sony

(I pulled the maintenance manual on it, it isn’t a VFD)

Arguably it might be a feature so you can listen to music without being blinded by the panel lamp?

My more recent (90s vintage) Yamaha has a dimmer menu option for that, and the last setting is OFF (the screen comes on for changes and switches off again after a short delay)

@DenOfEarth it has four dimmer levels but even at the brightest setting it’s pretty dim. I’ll try a factory reset to rule it out but I have a feeling that it’s an electrical issue

Ah fair enough. IIRC old LCD computer monitors used to be backlit by small fluorescent tubes on the edges. Might be the case that the electrics are ok but the tubes are shot? Anyway well done rescuing this from the junk and giving it a new life. Does the audio work? I've found the most common problem with older amps is that one side goes south. You can trace where the fault is with an oscilloscope but that's a bit beyond me.

@DenOfEarth it’s actually a Sony standalone HD Radio receiver, and the audio is great: not just for the digital stuff, but much better selectivity for analog stations around me. It’s just th display makes me think I’m having a stroke

Oh good! (about the radio bits, not the stroke!)
