No FM or AM in SX1050

[qguy]

Hi

My SX1050 FM or AM does not work, it was intermittent before and now its totally dead.
When press the multipath or the FM mute it makes a sound like when there is no antenna
all switches has been cleaned

AUX works with an external source.

Thanks in advance

Switches and controls cleaned with a solvent or deoxidizer liquid need to dry thoroughly before they can be expected to function normally.

It's not working again Switches were cleaned 3 hours ago.

Check the power supply feeds for the tuner board. There could be a loose wire: Or the ground wire from the tuner board. I checked the manual on HiFi Engine for the print. Three supply leads. (Longshot I know, but worth a look)

I check the wires all are intact and connected.

This issue would have to wait, got "bigger" issues at the tone/filter control boards

Checking involves a voltmeter at tuner board connections - visual inspection is only the warm-up...
