I hope someone can help me out. I have a Yamaha DVD DV-S5450 player where the disc tray won't open. When I power up the machine, an "OPENING" message is displayed, after a few moments it goes to "BLOCKED". I can hear the drive attempting to open the tray. I've tried to pull the tray out but it's stuck and I don't want to break it. Any help would be appreciated. With best regards Tom

Re: BLOCKED MESSAGE ON YAMAHA DV-S5450 DVD PLAYER
The DV-S5450 may use a belt-loading mechanism. The belt is typically black rubber band with a diameter of approximately 2 cm. It is commonly found in front-loading CDROMs for computers also. Often, as a result of age, usage, humidity, etc the belt snaps, rendering the loading impossible. The loading motor doesn't just pop the tray in or out. It also engages a clutch assembly that raises an inserted disk or lowers a disk to be ejected; this explains why you can't simply force out the tray. Clearly in your case all the electronic signals are there and the loading motor does turn.
Solution: switch off and unplug the unit and then open it up. Do a quick inspection to see if you can locate the broken rubber band. If you can, remove it and take it along with you to the nearest repair shop for exact replacement. If you are finicky around technical work, simply a competent person do it for you. Good luck.

This happens to us all the time. Here is the note I keep on how to fix it quickly:
When tray gets messed up, the drive wheel (with pegs that interlock with pegs on the tray) needs to be such that the tray slides in and out freely. Push tray all the way in. Turn on. Hope that gives a hint.
I had a similar problem...the machine, which had been great up until then, started to be very fussy when loading a disc; using a lens cleaner did not help at all.
I opened the disc tray and used a can of "air duster" with the straw attachment blowing in lots of air into every little nook and cranny that I could reach, especially in and around the actual lens area. The liquified gas under pressure must have been too cold as, at first, there was no improvement whatsoever when I tried playing a disc. However, the next day the player was working perfectly again.

What kind of disc are you attempting to play? If you are trying to play a home-recorded disc, the disc may not have been finalized for compatibility with other players. Try a commercial disc and see if you get the same message.
Solution 1: Most likely there is a foreign mechanical object obstructing the tray mechanism. If, like me, you have kids around every corner then most likely a curious little one has pushed something in to see "just what will happen". With some luck you can solve the problem by opening up the unit (power-off, unplugging first, of course) and doing a visual inspection for what shouldn't be there (pieces of paper, coins, toothpicks, fibres, etc).
Alternative Solution 2: Sometimes what happens is that the tray loading belt slackens over the years (age, humidity, over usage) and fails to respond quickly enough. In the absence of any obvious foreign object(s) this is a likely alternative explanation. Drive-tray electronics (called SERVOS) are programmed to expect timing signals to come within well-defined intervals of time. If this does not happen (such as due to a slack belt), then the condition is registered as an error. Try replacing the belt if solution 1 does not work.
I would imagine it's eitehr a Region problem or a parental level problem.
Ensure the region DVD matches the Region of your DVD player.
Also check the parental rating level within the DVD player is not active or set to 18.
