Question about Yamaha DV-S5450 DVD Player

1 Answer

"BLOCKED" message My DVD player has been working fine for years. I havne't adjusted any of the settings, yet all of a sudden it won't take a DVD. When I attempt to insert one, it spits it back out at me with a BLOCKED message. Even when I take the DVD out, and try to close the drawer empty, it opens up again with the blocked message. I've made sure there are no parental controls set, etc. Unless I manually power-down when the drawer is closed, it won't stay closed, and everything (even air) is BLOCKED. Is there a solution out there for this?

    The DVD player is a Yamaha DV-S5450.

    Thanks for the suggestions. I don't have kids, and the DVD player sits high up on a shelf, so I don't think anything's stuck in there. The 2nd solution sounds more likely, although after I wrote this things changed: after about a week of inactivity, I inerted a DVD into the machine and it played...for about an hour. After an hour it then began with the shenanagins again, with the blocked messaged, which rendered watching the remainder of the movie useless. The following evening we picked up where we left off.

    Then the next week it happened again. Apparently the machine was good to go for only an hour. I concluded that perhaps it was over-heating and that maybe there was a cooling fan inside the unit that wasn't working.

    Then the unit sat unused for a while.

    But lately, the last 4 or so movies we've rented, have worked perfectly fine. So go figure.

    So maybe your solution #1 WAS correct, and that finally, whatever may have been lodged in there kinda freed itself eventually, I don't know. Because right now it's working.

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.

When I try to watch a dvd it tells me inproper disk.... It worked fine for a year and a half then all the sudden won't play dvds

Try to clean the lens of your dvd player. Buy a cleaner for the lens. If the problem still experiencing after cleaning, you need to bring it to the repair shop for further checking. Maybe there's a part inside the player that need to replaced.

Suddenly, despite using the power cord, we get a "battery low" message and soon the player stops working. We've been using the DVD player for some time with no issues and this just started...

it is possible that the battery has been reset at a low level so it won't hold the charge. You may need to have it emptyed and then recharge it for the max time or you need to replace the battery.

Suddenly "cannot play this disk" on Sony DVD/CD..every DVD...CD's work!

I have the same problem. I have a 5 year warranty from the company I purchased the unit from. I am not sure if they will replace it or not. I am reluctant to buy another one with this known issue. We have enjoyed the unit for nearly 3 years with no issues.

Blocked error message

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.
