Seeing as I've lead you all down here, I'll tell you where I am.
They are not going to get a second chance of trashing this. Especially as my returning it will probably lead to that happening en route.
I have opened it up. I admit this means that an Ebay return is unlikely.
The transport appears to have suffered a blow, such that the tray was displaced far enough to the left to allow it to slip out of the rail on the right.
This is why it wasn't supported and could only come out halfway at best and with coaxing.. And in coming out halfway, it was pressed to the top of the opening and suffered a loss of paint. I hope I've removed all of the paint the was pulled up.
It was a fiddly but I was able to relocate the tray once I'd removed the copper shielding to get access.
Now, when I switch it on from cold, it makes a whirring/grinding noise, a bit like wheel spin. And then stops. This can be repeated 10-15 times or so until it will open and then immediately close, with more wheel spinning as the tray withdraws fully. But this is progress. Two or three more attempts and the wheel spinning is almost gone and the tray opens and closes at my command. It will then play a disc.
if I keep the player active, I can use it. if I leave it for a few hours, it will start all over again to refuse to open.
it takes a lot of wheel spinning before something takes a grip and it opens. When it does decide to play, it reads TOC almost instantly, and on some occasions, opens quickly and silently as you'd expect. But I have to repeatedly open and close it to get to that point.
I've left two stinking reviews. If they want to make things right for me, then the outcome may be reflected in the reviews. Otherwise, they will have to suffer the reviews there forever.
We know people that can fix this. I'd rather it was done for me rather than someone else.
