Luis401 Posted January 18, 2020 Share Posted January 18, 2020 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 Link to comment Share on other sites More sharing options...
Steve Herschbach Posted January 18, 2020 Share Posted January 18, 2020 If you have had it since 3003 and it was working correctly and is not now after repeated factory resets it sounds like it needs to be serviced. Link to comment Share on other sites More sharing options...
schoolofhardNox Posted January 18, 2020 Share Posted January 18, 2020 Have you tried another search coil?? Also try another battery cable? If you know someone that has another battery,try it too. I always like to eliminate the easy stuff first. 1 Link to comment Share on other sites More sharing options...

Luis401 Posted January 19, 2020 Author Share Posted January 19, 2020 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. Â Â 2 Link to comment Share on other sites More sharing options...
