Hello,
Few months ago, my Avin Avant started blowing the fuse that's behind the unit. This unit has a 15A fuse. As soon as I plugged in the unit with a new Fuse, it would blow it.
Since my unit was out of warranty and Avin was no help, I decided to take matters in my hand (Chatgpt)
1. Remove the top cover of the Avin Avant head unit. Should be two screws holding it down. One on each side.
2. Test the diode (mine was listed as D29) on the board. The diode should read .500 to .700 on the multi meter. If it's any less, it's most likely bad.
- This diode is located directly behind the main connector.
- if you have a small burn mark on the blue connector in the back like in my picture below, that's most likely from factory. After all, this unit is made in China.
3. You can easily remove the diode by desoldering from under the PCB. Then look up the diode number. Usually can find bulk on Amazon for few bucks.
- Mine was 1N5401. However I went with 1N5408 for better protection with voltage jumps.
4. Solder it in the same way the bad diode was. The side with Stripe on it is the Cathode side. The side without stripe is the Anode side.
I recommend take picture of the original diode before removing it.
5. Solder the new one in. Test the head unit.
Mine is working great now with a simple few dollars fix and have plenty of diodes now if it goes bad again.
Hope this helps anyone who is having similar issue.
