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/ 905-940-5089 Good Luck

SOURCE: how to fix a insagnia dvd player

Simply put. Don't ever purchase an Insignia product ever. I Have the same problem with a product I purchased just over 3 months ago, and the Insignia Customer service rep Sandra Larraburu gave no help to me other than the following solutions.
1. Make sure all the cables are plugged in right (Are you serious Sandra?)
2. Try a different DVD (I told her in my original email that I had even been trying different DVD players, so of course that was done)
3. UnPlug it (Is this a solution?)
4. Plug it back in (O....kay)

Then she proceeded to tell me that because the manufacturer's warranty had expired after 90 days, that I was entitled to no resolve.

Note Insignia states this "All of us here at Insignia strive to provide the best quality products
and a
great customer care experience"

If that is the sign of a company striving, I've learned my lesson.
No Insignia for me again.

hi,

please try cleaning the lens manually with cotton or check if the flexible board connecting the lens to the mpeg board is ok or may be loose. if the same problem appears, maybe you've got defective lens or affective mpeg board.

Make sure the disc is spinning. This might sound crazy but try turning the whole player upside down and see if it plays.

Put dvd in it says no disc or disc error


The problem is caused by the laser pickup assembly, the laser cannot read the disc because the pladder motor is not turning. The only option is to replace the assembly, not cost effective to repair, cheaper to buy a new replacement.

Bush portable DVD player will not load my disc


Hello
Just put in an audio CD disc or an MP3 disc, and see whether it reads them or not. If the player can read these discs, and only refuses to read DVD discs, make sure that the laser pickup unit of it is faulty, and should be replaced with same type and number. If none of them reads, there are two possibilities, the first one is of laser pickup disc itself and the second one is the strip wire [a flat flexible cable connected between laser pickup unit and the mainboard of the player] is faulty. First replace the strip wire. If it helps you, it's OK. If not replace the laser pickup unit also. The strip wire can be bought from most of the electronic spare part shops at your town. When buying laser pickup unit, its number must be noted, and exact replacement should be done. Otherwise, it won't match with the main board. OK.

hi,
You have to check the laser pickup unit of you dvd player. In your dvd palyer the laser pickup unit is faulty. There are two lasers in DVD players laser unit. One for reading the DVD and the other for reading the CD. In your player the DVD laser is faulty. As it is one module you have to replace the laser pickup unit as a whole. You will get it from any electronic spare part shope near to you. As a whole i mean Normally laser pickup units come with its mechanism like in the picture . May have slight difference with your one. picture is only for reference. Its part number will be written on the bottom side of the laser unit. you have to take the laser unit as sample when you are going to buy the same. If it is reading cds it is sure that the laser pickup is faulty. Its a regular complaint to dvd palyers. To replace the laser pickup you have to remove the cd loader and have to remove connections to it.
ok

When I try to use my dvd player I put a disc in it says loading them it comes up and says bad disc, it will also do this if there is no disc inserted into it, can you help me? I don't know the model #...


Hi,

how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it cannot read data/files on DVD discs.

To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or a mechanism problem.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all DVD discs again.

Yours sincerely.

When i place a dvd to be played it reads no discs


The Laser Pickup Assembly is the problem, caused by a weak laser pickup lens, or the pladder motor that the dvd sits on is defective. One possible solution clean the laser pickup lens with a Q-Tip and rubbing alcohol. If there is no change it is more cost effective to replace the player with a new one than repair.

Dvd player will not open


the problem is internal and the only way is to bring it back to the store you just bought it. because it is still under warranty, since it is just newly bought.

RCA DVD player model DRC105N that won't read discs anymore


If the DVD is not reading any CD, then it is often a lens problem.

If th lens cleaner does not work the unit must be taken apart, to clean the lens pickup with isopropyl alcohol and soft cotton tips.

In some case is necessary to replace the lens pickup, as this is defective.
