Question about Sony Walkman SRF-M37V AM/FM/Weather/TV Radio

1 Answer

I believe I need to replace the internal battery for my sony walkman srfm37v as I've had it for a long time and even if I install a brand new triple A, the hold key won't go off (even by sliding the switch back and forth). Took it apart, cleaned up battery contacts, blew air through it and I did not see a place where there might be an internal battery (like a watch) that holds the station presets. I cannot turn the radio on because I cannot get the "hold key" to disappear from the display screen of the radio

There is no internal battery on the Sony SRV-M37V. Presets are held in non-volatile RAM and don't need power to maintain the settings.

Your problem is that the hold switch is not disengaging. Either the contact below the switch has gotten gummed up and won't release, or perhaps the switch is broken.

You can try spraying a tiny (very tiny) amount of Contact Cleaner (available at Radio Shack for less than $5) into the switch. Or disassemble the unit to see why the switch isn't making contact like it should. Hope that helps!

The battery does not hold charge. It is weak. Replace it with same type number. Brand name of the battery isn't a matter, check its type number printed on it.

Is it possible to replace the battery in my Sony MP3 Walkman model NWZ-E464

From the user guide:
  • When usable battery life becomes half the usual time, even after charging the battery fully, the battery should be replaced.
  • Consult your nearest Sony dealer.
This would lead me to believe the battery is replaceable.
