The relabeling of parts is very common for parts you buy direct from China (Like Temu/Ali etc). I have examined several parts for a distributor. They melt parts from PCBs above a fire, then hit the board on the ground and parts drop off. Then they remove the marking by grinding and relabel them. For IGBT/MOSFETs etc they spotweld 3 new pins, rework and polish it with tin and sell them as new. This goes on a very big scale. A batch of IGBT I tested was about 150 pieces. The IGBT's were not even close to their specs, some were IBGT but an other type, some mosfets, some were dead. Recapped a few of them and the dies were all different. And that all for a part that they sell for something like 50 euro cent. Most hobbyists do not know, they think they have done something wrong or while repairing that part was not the cause and so they are satisfied buying in China, not knowing the cause were cheap fake parts. If you are very lucky they are original but used and given new pins.
My six has been turning it's self off, as well as back on again sometime, sometimes it wont boot up for acouple of trys then works fine, other times it turns off a the ! Flash's on the screen. Would this be the course, bad connection. Cleaned battery terminals with no change. Still under warranty, is this a minelab fix.thanks Craig
Already got my attention with the title.. I have just started to have intermittent noise that is impossible to cancel out or use.. Comes and goes.. I have been advised that its known and the boards are being replaced
That is some very bad soldering, is that how it leaves the factory ? I see a lot of cold solder joints in my work, often the result of the owner butchering the thing with a Chinese soldering station. It is a sign of not enough power and a to high heat resistance (combined with lack of soldering skills and fake Chinese solder and flux). I use 2 Pace MBT stations, they can solder everything. I use a OKI hot air station. Customers pay for the repair so my soldering must be first class.

If it’s under warranty it’s best to get Minelab to repair it.

I have fixed a few of these noise issues, also dropping coil handshakes as well. The issues can be cured.
No white paint - YUM

The whole circuit board is a multilayer heatsink.
