> [@sandro](#): > > It was the fact that all the screws and contacts inside the appliance were loose, there was not even a tight screw. So the technician’s job was limited to tightening all these screws and contacts well, and in fact I paid a very modest amount (but I have to say that this technician is a friend, and he does it as a hobby). Congratulations and thanks to your friend for lending a helping hand. In your estimate, what could have caused contacts and a few screws to go loose? ---

> [@Birger](#): > > Curious question: How can anything break when you turn it off? I find that strange too! Probably something was on edge waiting to happen and it conincided with turning the the P15 off! I hope it turns out to be something small, easy and quick! ---

No, I (ALWAYS) turn my P15 off first with the remote and after that I use the main power switch on the back of my P15. ---

The technician said he had to tighten all the screws inside the P10. She speculated that the cause could be shipping or transportation. I bought the P10 at least 5 years ago, but since I installed it I have never had any problems, until I recently moved it. ---

Screws excite by electricity at 60 Hz will loosen over time as will material creep. Most solids are liquid under temperature and pressure. When i put in dedicated 20 amp lines for audio I tightened every other terminal in the fuse box based on advice I read. Everything seemed finger tightened. I also went back two weeks later based on same advice and installs I just made had all loosened. ---

Hi Vmax, thank you for your contribution. In fact, yours would seem to be the only possible explanation. ---

Yes the Transformer in @aangen P-20 sounds like it is loose develops a hum with his big amps plugged in. I actually saw cleaner power on my P-20 after I tightened the breakers, bus bars and screw connections along with main power coming in from the meter to my main supply. I was getting three to six turns everywhere until all were real snug ---

Hi everybody…after not even 2 months my P10 is again faulty: no signs of life, display turned off, and no current in the sockets after I turn on the rear switch (you only hear a few weak “clicks” inside the device). So the previous intervention of the technician who had tightened screws and connectors was not at all decisive, as the P10 again presents the same problems… ---

I’m happy for you, if it’s working well it’s already a great thing, mine doesn’t work in any way. Please, would it be possible to know what the problem was? Thanks! ---

The problem I had was that it burned fuses for no reason, and my knowledge, so I thought there was a big fault with my P15, but it wasn’t. It just had burned another fuse for me, without my knowledge, so when the place who checked it up changed fuse in it again it worked. ---
