Something amazing has happened. The phone repair shop I sent it to decided to dig in deeper and tried desoldering and resoldering the chips on the pcb and amazingly got the device running. There is still a weird issue. I think the charging circuit/battery has had some damage. After first time charging it up from the repair shop, my dap went from 100% charge to 67% in an instant after powering up but since then it's draining normallly with regular usage. It even ran on standby without losing any charge. Anyone knows what could be the issue?
Anyways, I am relieved that it is working. Saved me a lot of bucks.
Couple of points that might be worth mentioning. BTW this is not a criticism of you, or anyone else. It's just things I've learn over some time repairing products like these and mobile phone, etc.
On a lot of electronic devices the charging port is a weak link. I've probably repaired nearly 100 various phones, ipods, kindles and various other devices where the charging port has been damaged, either because someone was maybe a little too forceful, or the unit was dropped whilst plugged in (and it landed on the plug and broke the socket). I seen so many people put in cables whilst forcibly wiggling them into the socket. They then wonder why they have problems and the unit won't charge anymore.
Unfortunately most manufacturers don't take this into account. Apple iPhones for example have beefy screws that clamp the lightening connector socket to the case directly which is great. The front screen also acts as a "clamp" down on top of it. Other manufacturers unfortunately don't use anything and simply solder the connector to the main PCB and maybe use some glue to hold it in place. Which over time is not really strong enough. Kindles use this setup and they can break very easily. Thankfully it's on a separate PCB with a ribbon cable so easy to replace. You can't re-solder it, the connections are too tiny.
My first thoughts when I saw your post was that the USB socket had partially come away from the PCB. A classic sign of this is the wiggling of the cable to get it to charge. However your response above makes it sound something far more major and I'm really sorry that you are having the problems.
My other recommendation/advice. Please only use a 1 amp charger for this DAP. I used an newer iPhone charger (2 amp) once and it badly upset the DAP, causing the battery level to jump around all the over the place and when I unplugged it, the level started at 100% and quickly dropped to 60%. It really wasn't happy. I had the same issue with an iPod Classic. My gut feeling is this will over time, damage the battery and might damage the player. Maybe Pioneers fault for not including a 1 amp charger with the player.
Some devices do not like high amp chargers and this DAP certainly seems to be one of them. So I always use a 1 amp charger (very cheap off the internet) and I leave it charging overnight. Takes about 4 hours from 10%. Seems to work as I still get 8 hours of playtime even now.
I've used the Pioneer every day for about a year and a half and thankfully had no issues with it.
Like I say, this is not a critism of anyone on here it's just some ideas I have. Pioneer did not make this player to be very strong from a build quality point of view (headphone socket for example) and it certainly has to be treated with kid gloves.
Like someone mentioned on here I get the impression the Sony players are built like tanks, however they can be more expensive for sure.
