I would suggest replacing the fuse anyway. I found that my fuse blew and the plastic held it so close to the other piece that it seemed fine, when it wasn't. My fuse was giving me a reading even when it was blown, but it was really low because it was blown.

@Technopro Yeah I'm dead sure the fuse is fine. I have another working EZb, and I switched the fuses just to make sure I'm not getting a false reading. The fuse is fine.

I always use a continuity tester built-in to my multi Digital tester to test fuses. Best way to find out and always correct. If it buzzes its good

Sometimes occam's razor rules... have you tried removing the chip and then re-seating it? Since you said you are not reading +v on the 5V pin this maybe a moot point... but you never know...

@Richard R Occam's Razor is my credo...my designs may seem intricate but my mechanics are always simple... That's actually one of the first troubleshooting tricks I did...took the chip out and re-seated it. Same with the BT. The only thing that boggles me is I never mishandled the board, it's always protected...it just stopped working. But like I said I usually figure stuff out I'll keep trying.

A schematic would really help.

D.J. has videos on troubleshooting the EZB. He will tell you where to look for the 3.3 and the 5V. If you are not getting those voltages the regulators need to be changed. If you send a request to D.J. he will probably tell you to send it to him and he will fix it and send it back. He usually pays for parts. You need to pay shipping to him. But, ask him and see. Request an RMA#.

Heres the Tutorial.

controller troubleshooting.

Good luck.

@Doombot... I will have an extra V3 board to sell very soon (as I was one of the lucky ones to get the first shipment of V4)... It's yours if you want it...

@MovieMaker

Already tried that, and then some. but yeah I may contact them for parts. Thanks!
