Hi ! Greaaat neeews here !! A friend come at home today, we worked on the GPX. The Ribbon cable cleaning have not resolve the problem... After made some test with each elements from his GPX on mine, we find the problem comes from a bad contact in the disc. A simple solder should resolve the problem for sure ! Thank's to everybody for your help. Best regards from France. Luis.

Thank's, I will try this tomorrow ! Maybe it will be that too...

Yes, A friend have a 4500 too. We tried all, the problem come from the box... Inside nothing looks strange...

Hum.. I think too ! Thank you I'm also waiting from the minelab repair service France...

Hi all, I'm from France, working with a GPX4500 of 2003. Yesterday when I started this old guy, I was affraid by this problem : - Sound when the treshold start is strange. - The autotune (research for free frequency) is a stable sound, with no variation. - And no power ! about 5 inch max for my metal digging pickaxe. I tried some factory resets, but the problem is always the same... I tried this one with another disc, trakking button, cable, headphone, battery, the problem come from the main box... Anyone knows this problem ? Thank you and have a nice day. Luis
