Mitsubishi DD6040 - Laser not turning on

The loading carriage broke and the bottom disc that raises to engage the DVD had come off - which was causing the tray to stay open as it would not close (the disc was in the way). I placed the disc back on the small spindle but now the player will not read a DVD. The laser light does not come on and the DVD will not spin without help. Is it time to buy a new player or can this be easily repaired?

SOURCE: Mitsubishi DD-4030 DVD not engaging. Disk Error,

This could be one of three things

1. Dirty reader head:- If you not got one, ge a DVD lens cleaner run it 3 or 4 times see what happens

2. Maybe needs re setting, rather like a PC, unplug, disconect ALL leads leave over night and re connect see, this worked for a friend of mine recently.

3. The reader that locks onto the digital date is corrupt.....time to buy a new one !!


More expensive to repair than replace

DVD player automatically stops and turns itself off, how do I prevent this?

Warning: Laser inside! If you want to open it up and troubleshoot, make sure you don't point toward your eyes.
Check the nylon laser carriage to see if it slides laser from center to outside line. If it sticks, it's probably shutting down from not properly reading a disk.

I have an Audiovox D1020 DVD player that when a DVD is put in continuously tries to load the DVD without any success. The DVD is not a copy, but the original store bought version. It works on my other DVD...

Did you play other DVD's on the same because it may happen somtimes that one particular player may not be able to play a dvd which is being played in other systems

Disk won't load

First make power reset.
  • Switch off your DVD, remove power card from wall out-let. Then connect again and power-up.
  • Use CD/DVD lense cleaner to clean the lense.
  • Then try out.
Thanks

DVD NOT RECEIVING DVD DISCS

Hello
The loading mechanism has the trouble. The inserted CD or DVD does not engage into the laser assembly unit properly. It may be due some fault with its loading motor or loading belt. Check these.

Incorrect disc

Hi,

The first thing i would suggest you to do is a hard reset by unpluging the the player for 30min and then try again.

If this does not solve your problem then please see if the player tries to read the disc.
Load a disc and listen.Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable.

Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word.
This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces.

You could try to clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try.

If you actually see dust on the lense, then its just that simple. clean, close, play.


It may also be worth your while to check on the small shafting that guides the carriage of the laser pickup. Dirt, grome, dust and solidified lubricant can cause stoppage of the carriage and the laser eye then fails to read the next track. Please refer to the image below.

If the problem still persists then you will have to get it repaired and thats the only solution..

Goodluck..

Also Make sure your box is not blowing really hot air and nothing is right behind it blocking it.. Turn it off for a few minutes and let it cool down and then give it a try playing the discs..

Durabrand DUR-7 portable DVD player

Hi,

Most DVD players that would display such a message even with a known good disc inside signifies that the that the laser eye/lens is not reading the disc. This could probably be attributed to:
1. dirty, damaged, inverted, blank, un-finalized burned CDs or DVDs;
2. defective, weak burned-out laser eye/lens;
3. defective slider shafting (where the laser eye's carriage moves.

A few things you can try:
1. Use a CD cleaner (readily available from most computer shops);
2. use a can of compressed air and blow through the inside of the loaded disc area;
3. gently tap on the top cover where you estimate the reading/laser eye/lens would be;
4. gently press on the tray door once the disc is loaded.

Should this not be corrective, perhaps your best bet would be to seek the services of a qualified professional such as those in a Service Center. Alternately, your friendly neighborhood electronic shop should do just fine.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kindest regards.
