Re: Keeping the DVD player going
The problems with dvd & cd players, are located in two areas - both mechanical.
#1 On the laser cartridge, there are minute springs that hold the lens while a coil and magnet arrangement moves the lens (similar to a speaker cone) to focus on the disc. These springs become weak and break on the cheaper models - Therefore it can't see the disc information clearly - and the output is not digital - it says no disc.
#2. The main bearing at the centre of these drives can run dry and start to become rough. This may cause the disc to wobble enough to start to vibrate. This failure is characterised by a noisy drive just before giving up.
So use a product that sources a quality optics package, and a decent framework.
It's amazing that the electronics can compensate for cheap build quality - but they do! - a bit like good suspension compensates for bad road quality.

no need to tighten the cap or whatever, that's the problem there is with the switch control, which must be touched when the lid closed. you just need to open the DVD case cover, then locate these switches, make sure the switch is still normal or not, if it is normal that you only need to give a little pad on the suppressor to the switch. suppressor usually exists on the DVD casing.
it sounds like you have a heat problem,try to put your player somewhere that it has alot of room to keep cool,i've noticed some people put there players on top of the t.v. or close to other electronics,the whole key is keeping things cool,let me know if this helps because you have a very good player.
OK - There is nothing that drives the door to close and stay closed. There is a little plastic gismo the locks onto a little protruding tongue in the lid keeping it closed. To release the lid, you must press the lid foreward so that it releases the lock in the little plastic gismo. I found this out only after removing the board above the main deck of the player and which, fumble-fingers me, I managed to damage the board and will have to replace it along with the little plastic gismo that holds the door closed. I am not sure if either of these parts are available as I have had the unit for quite a while. This leaves me in a quandry as I really did like the little player. It was a dandy. So, if you ever get an inquiry on how to keep the lid closed on a JMC_800, tell them to replace the little plastic gismo and that will do it.
Check to see if it is not the lens, but rather the fact that the little tab on the lid that closes the disc compartment is not making firm contact with the mechanism that tells the disc to play. I had the same problem (player would play for a couple of minutes, then it's stop and I'd get an "Open" message. I called Mustek and they unhelpfully suggested various tricks to do with the lens carriage, none of which worked. On my own a carved a matchstick to the shape of the tab on the lid, and stuck it in there. That worked! Eventually (since you can't watch it with the lid up), I just put some duct tape (a little pice) around the tab, and that has worked like a charm. Makes it hard to open the lid again (I use a knife to pry it up), but hey--the player works now!
sounds like the switch to tell the unit that the door is closed is either loose installed at factory incorrect. or your grandchild has closed the top a bit vigorously and snapped a bit off it. open the lid and there will be like a plastic pin coming from the lid,check to see if it is broke. if not take it back to shop as its a manufacturing fault
Not sure it's a solution, per se, but I discovered that my Matsui was acting as if I was opening and closing it, so I guessed that it was the lid. Once I put a paperweight on the "Press to Open" part of the lid, the DVD played through. I'm looking how to fix the lid but that's a workaround for now. Best of Luck - M
I figured it out, it was the little plastic sensor stick that tells the unit that the lid is closed therefore reading the disc. cheap piece of plastic that has surely snapped on many a unit. good luck replacing it. i rigged it though problem solved
