I haven't tried this yet, but based on the description, it looks to be the spindle motor not functioning properly. Read below: By BobbyR1234 Rank: Guru Rating: 86%, 86 votes

The most common mechanical problems that can prevent a dvd player from playing or reading the discs are the following:
1. The spindle motor not functioning properly (this is by far the most common, if the spindle motor is not spinning the discs then the optical lens can not read them). For the most part it is an cheap part to replace averaging around 25-25 dollars if you can replace it yourself. If you do not know how and have to take it to a repair shop expect to pay 50-75 dollars in labor. The key is to listen closely when you insert the disk into the player, you should be able to hear it spin up. If you hear nothing then that is most likely the problem.
The unit has a defective optical pickup. This is the laser diode inside the DVD drive unit. It is a common problem which requires a service technician to replace the pickup. It is expensive to replace. The pickup is $62. Panasonic part #RAF3331A. Good luck finding one cheaper, but if you do please let me know. Joe
Just had exactly this happen to me tonight. Was working fine last night, today I put in a CD and yep, sure enough, the laser head is running up against the spindle about 4~5 times, a quick 'spin' and another 3~4 attempts with one more spin and then it's shutdown with a "NoRead" error.
Not really happy about this, prior to this event it was the best DVD player in the house with it having no skips/jumps/lagging like the other cheaper players.
Interesting theory about the Pb-free issue, could well be a tin-whisker issue but it's going to be really difficult to prove either way. Don't have a reflow oven handy alas :(

The noises that you are hearing will be the spindle motor trying to spin the DVD as the lifting presentation tray for the read/write head has not located, if the media is not spinning this will never be able to read the lead in on any DVD as it has not presented the disc in the correct place.
If is is out of guarantee then I suggest that you check to see if the DVD is spinning by removing the top cover with the power OFF then eject the tray and try to load the media a small touch of the DVD in the clockwise motion should cause the media to start spinning, this is for diagnosis only if this is the case then the spindle motor will need changing
This sound like a problem with the laser read circuits and it may be solved with a simple cleaning and using compressed air to clear the unit of debris .To do this you must take off the top cover of your unit by taking out the screws and lifting the top off. To clean the laser head you should use cotton swabs and isopropyl alcohol. put a small amount on the cotton swab and rub the swab gently back and forth over the head, until it seems bright and shiny.Check the transport carriage for dust and debris and also the gears. all these must be clean for proper operation. You may want to put a little lithium grease on the gears and guide rails for smooth operation. All this should be done in minute amounts so you do not over do it and cause more problems. If all this fails to allow you to use you disc player, Then you probably have a worn out laser sensor and will have to have it replaced. If under warranty send it in and if not try to find the part number and order it and either take in to a service center for repairs or do it yourself. Hope this helps you with your problem.
Mine done the same, suddenly froze in mid play and would no longer read any discs. Kept saying 'no disc'.
In a slight bit of frustration I gave it tap on the top front middle!
Strange to report that it has worked perfectly ever since! (fingers crossed).
Bit of a cowboy fix but it worked....
1 - Run up speed is not sufficient due to motor wear.
2 - The laser head sits within a 'plastic' runner, which wear down slowly, causing the laser to be misaligned - therefore not reading adequately.
Depending how adventurous you are feeling - you could dismantle the unit - and 'space off' the laser unit (Single piece of paper) this will lift up the laser.
Or you may be able to adjust the calibration power of the laser using a variable pot (unlikely to be available as these are generally hard coded nowadays - and not physical pots)
Not spinning disc
If it spins with a little help from yourself replace the spindle motor with improved motor, part number: RXQ0749A
Unable to detect discs
The laser head was the culprit. Replacing it fixed the problem. (Laser head code GRP6278A)
Difficulty reading cd, if it does read the sound is strange and sticks
Replace C101 (1000uF/16v)
If you tryed to clean it and it didnt work you could have several things that went wrong and depending on what did go wrong will tell you if you wanna spend the money or buy a new one. If the laser assy went bad you probably will buy a new one. if you find a good authorized repair shop, then it may just need cleaning and a servo alighnment. or a bad spindle motor, or your missing a switched voltage on the power supply could be missing. Im sorry to tell ya that there are no user serviceable parts inside this unit unless your a tech. The only info i have for emerson is the help # Maybe they can show you where to take the unit to be servced/
