Unit is dead

Unless your house circuits are incorrectly wired, the lights shouldn't go out. Lighting, heating and power outlets should be on separate circuits and individual circuits for stoves, dryers and water heaters. Also separate circuits for each floor too.

Anyway an IC (integrated circuit - a 'chip') wouldn't cause this. You have a dead short in the power supply unit which takes the mains voltage and reduces it to the voltage that the unit uses, probably 5 or 12 volts.

Did you check the cord to see if it has been damaged? Sometimes, cats, dogs, mice, or continual bending or kinking can cause the insulation to fail and when the wires touch, you have your dead short.

Sounds like the water has damaged the controller or the wiring.

To be honest if you have taken it apart then it is fried and the circuit board is not easy to replace i recommend a new radio, next time run your usb wire loose as you can so it wont never snag

Check and replace the damaged component/s at its audio output stage circuit. If you wish to get some details; check the site linked here. Pull up older posts.

replace the fan blade then clean the unit to get a very good condition

not sure how long you have had this, but if the unit was completely turned off or battery completely dead, you have to hold the power button for about 15 seconds for the 3000t to start up...assuming the charge light at the top right is orange (that means its charging) no light means its not charging, green light means fully charged. if there is no power light on at the top right of unit, either the charger is bad or the port on the board is bad (which i do have) good luck and hope this helps. bill

Low voltage Tx actually OK. Restored vaporised circuit tracks on controller board, fuse and interior light globe. All working OK.

If the AC power source (outlet) is ok and the line cord and fuse are ok but the unit is completely dead, you may have a problem with the internal switching power supply.

Locate the switching power supply and see if there is a fuse on its circuit board.

Completely dead units are typically caused by a failure in the power supply section.

Please let me know if I can be of further assistance to you.

Good luck!

CHECK MAGNETRON RELATED CIRCUIT, HIGH VOLTAGE CIRCUIT, CONTROL CIRCUIT,AFTER CHECK MAINS FUSE.

You would first have to open up the unit and look carefully and see what is maybe broken or out of place. Look for loose connections. Check damaged parts.
