Archt One Speaker(discontinued)

[oPKnives]

Hello all I have been attempting a repair on a Archt one speaker for about a month now and I just can’t figure it out. I’ve probed around, I’ve tested the speakers in a home theater just to make sure they work and they do just fine, but when put together I get no sound through BT or through Aux. I cannot find any forums or any schematics on the device for reference so I’m stumped.

Obscure cheap Chinese made stuff is rarely repairable, and spares and information are almost never available.

If you want to try and repair it, then you would need to reverse-engineer it to whatever degree is required.

I don't know if I can help, but i will try. I need pics, top and bottom of the board.

Check DC power, then replace bulged lid e-Caps and record DC voltages on any suspicious IC with part numbers , pin # and voltages.

they might not be worth the cost or repair. These are known for good bass and lots of distortion.

Look for used Yamaha solutions.
