Re: "loading" at startup
First, let's 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.
Try holding in the start button, -while turning the power on at the wall.
Keep the start button pressed for a good while.
This quite often seems to "wake-up" stupid machines.
Worked today for my DR MH30.
If you contact JVC customer service you can ship it to their service center and they will fix it (usually free for this issue) but they are slow (~1month) and you will have to pay for shipping it there
After getting a "no disc" reading, I opened the player to the ribbon connectors and noticed one was slightly bent on one side. I too a screw driver and placed it under the ribbon and with another driver, flattened it back into shape. I blew air around the unit and brushed the lens with a brush. It now works perfectly!

if you have a jvc dvd vhs burner dr-mv1s or the dr-m10 with the loading that continues to flash with no control of the unit at all there is the first step to take witch is a master or hard reset. done by holding the stop and power buttons at the same time for 10 or more seconds till it powers of then on again.
if this does not work or has no reaction to the unit at all them repairs will have to be made.
i have scowered the internet for fixes for this issue and have found a few interesting things but nothing concrete at all. but lead me in the correct area of the issue. although jvc was fixing these for free at one time they are no longer servicing them under their "free fix"
the problem with the unit is the power supply and although i found that easily on the web. i could not find what the exact problem was untill i did my own diagnostic testing and found that capasitor c5207 on the power supply board was bad and buldging/leaking. it is a 1500uf 6.5v @85 degrees witch i used a 105degree due to the temp and relating the issue with a bad design flaw. so use the higher temp rating one to insure long lasting use.
don't forget to preform the master/hard reset previously mentioned above and you will be back up and running in no time.
This player is equipped to do a self power on test to all pain parts of the player to assertain everything is ok. The blue light will keep flasing until it completes its task and then the blue light will stop flashing and you you can start reusing it.....................sodeep

It is pretty common problem.
If all of your DVDs are having same problems,
it is most likely either optical sensor is at fault. The other could be the actual loading mechanism problem.
If the dvd tray(drawer) closes all the way in but the DVD disc never completes the loading(reading) procedures, 1) it could be simply dirty or damaged disc. 2) the optical pickup device (eye) is dirty or just went defective. 3) sometimes the drawer tray that houses the DVD did not complete to engage in disc reading position can produce this result.
I would suggest: first check the position of the drawer and condition(s) of your DVD disc itself.
If the pickup device(optical eye) is dirty or defective, that needs to be serviced by a qualified technician. or contact JVC service center. Their information can be found at http://support.jvc.com/consumer/support/support.jsp?pageID=10
