I got a Pioneer DV-310 last August and it started giving me grief from the beginning, as I described in this post:
Well, I should have returned it for a refund then, but it started working again, and, aside from one minor hiccup a few months back, has worked fine until last week. All of a sudden, the tray will no longer open. It comes on, I press the open/close button (on the remote or the unit itself), the display reads "open", but nothing happens. If I press the button again, it says "close", then "loading", then "No Disc". This is thoroughly annoying. I could send it back to where I purchased it, but I would have to pay shipping again for both directions, and I'd almost have enough in the shipping costs to buy another player.
EDIT: Even the USB connection doesn't work, as I just figured out. I can plug a flash drive in and press the DVD/USB button and the display says "open", then "Close", as if I have pressed the open/close button instead.
Anyway, the point is, I want to find out if there are any known issues like this with the Pioneer DV-420V model. From what I've read of this thread, I don't think anyone has mentioned any problems of this nature, but I thought I would ask in case there are other people reading who have had such a problem, or heard of it, but just haven't mentioned it here. I would really hate to buy another Pioneer player and have the same problems crop up again.
I think what I'll do this time though is buy a regular Region 1 unit, then apply a new firmware to make it region free. I am convinced that the people who modified my DV-310 did something to it when modifying it, because it was having issues from the very day I received it, and the front display has never been exactly "right". By that I mean it has always shown "SAMPLE" when I first turn the unit on, which I don't think is what it's supposed to show, and that makes me wonder exactly how the player was modified.
Will I be okay buying a Region 1 player from Amazon and applying the firmware myself? Also, I see on Hkan's site that there are two "StM" firmwares for that player. What is the difference between those two and which should I use?
