My dewalt radio turns on without sound - Dewalt DC011 AM/FM Radio

Either the output stage of the radio amplifier are faulty or the speaker(s) are open circuited. Unfortunately there is no easy fix without a dismantling of the unit and testing. Sorry

This is what dewalt is saying...The Dewalt 12V/20V MAX work-site charger/radio functions as an AM/FM radio and recharges your 12V/20V Dewalt batteries (batteries not included). The 3-stage charger can recharge your batteries in as little as 1 hour, and the radio can run off 12V/20V batteries for cordless operation

• 2 AC power outlets offer more versatility for jobsite power
• Auxillary & USB ports allows for connection to CD, MP3, portable satellite receivers, and other digital audio devices.
• USB port allows device to be charged via USB when radio is plugged into a wall outlet
• Class D amplifier, woofers and tweeters provide full range of high and low sound for optimum sound quality,( hope this helps)

it is sound sound controller problem.

Sounds like you have a more serious problem than the fuse.

Contact DeWalt for a warranty replacement.

Ensure the volume is up,try tuning on all frequencies and ensure you are on the right bandwidth. If you still don't get a signal then check your speakers to see if they aren't disconnected in anyway they might be faulty and need replacement or it might just be a wire that needs to be soldered properly.

Check thoroughly to see if the wires connecting the speakers are still intact.

Replace the two AA batteries in the battery compartment.

Try and plug something in the aux. If you don't hear sound out of the aux when you plug something like your cd player in then your speaker cables have come off the circuit board or the out put transistor has gone on the radio. Sell on Ebay these go for a good price faulty.

There's a good chance they fried it if it's designed to run on a 120v circuit. The main part that turns on the LED might have handled it, but the more sensitive areas were probably overloaded. Does it work with the battery in it?

Try taking the AA batteries out and then turn on again without the batteries.

when you plug it in to ac volt did you hear any single click sound from the radio?. if no it could be just the fuse problem only. remimder radio has 2 fuses 1 for ac & 1 fuse for dc operation..fuse rating not the same.
