Who made the magnavox bd 3902

Hi to all,
Hi @Doug,

Very probably a rebadged Sanyo TPM-2170 or TPM-2175 combo 2" B&W TV, AM/FM radio & digital LCD clock.

see an assortment of Sanyo models on E-Bay/Pickclick here :

From memory, some models were multistandard, USA M standard & European CCIR B/G with 5.5MHz FM A/V carrier spacing + system I (UK), 6 MHz audio spacing.

There is a silver button cell inside to power the LCD clock.
It's only a clock, no digital frequency readout.

Best Regards

Thanks for the info.
The clock works.
I didnt use the original sealed button battery
As it was unique still with the unit and most
Likely bad.
Everything works.only think missing is the top packing
Foam piece for the box.
I have no idea we're that's at or even still have it.
Thanks
Doug
