After owning 3 insignia player's, 2 WBRDVD and one "3" model, they all suffer the same fate, esp home burned dvd's they will not load and just says NO DISC.
You know it's gunna happen once you load the disc, you can hear a double rattle sound from the drive.
Well having nothing better to do this morning I decided to pull the cover and see whats going on, the drive is SATA based so possibly a aftermarket Blu-Ray PC drive might be altered and mounted in the case like I did with a older Vinc dvd player 5 yr's ago.
Well get to the FIX......With the cover off I put a lil pressure on the center plastic disc that keeps the disc down when the laser assembly moves upward....it Loaded!!
So i figured the disc is "slipping" do to the motor is not grabbing the disc in the spit second it needs to read to find out what it is.
First I tried to add a thick metal washer and glued it to the center white plastic disc that aligns the disc, I figured the "weight" would keep the disc from slipping, still had a error, so i removed the 2 screws and removed the top drive cover to expost the laser, well i used alcohol, Q-Tip and cleaned the rubber circle the motor uses to spin the disc......It Worked!!
Appears dust and crap get's built up on the cushion/rubber ring and the disc does not spin fast enough on initial start.
I did it to all my players and now they are working like they used too..
Think about it, these players all worked fine for the first 2-6 month's, all you have to do is remove the cover and drive cover and clean the wheel.
I even tried to apply alcohol using a Q-Tip to the inner side on a DVD and let it clean off the ring without removing the cover's, It did work.
I dont know if trhis is a permament fix or temporary, maybe somebody with more knowledge can fix this further.
All i know now it's not the firmware or the laser being weak that's causing this.
