Fantastic - my daughter's Panasonic LS50 gave many years service until code H03 appeared. Thanks to your fix, it's working beautifully again! We're very grateful, thanks!

just wiggled lens mech works dandy

I purchased my LS50 over 16 months ago. I had a H03 error before and it went away after sitting on the shelf for three days. It worked ok for another couple of months and then stopped again. The screen says reading but the motor is not spinning. The machine is for my 5 year old daughter for her cartoons. Believe it or not, she pointed out that the laser lens is in the wrong place. When at resting location, the lens should be parked near to the spindle in the middle. The mechanism to move the lens backward and forward sometime get stuck at the end of its travel - furthest away from the spindle. If your player is out of warranty, then you maybe able to try this. Open up the bottom cover by taking out the screws - 10 or so. This will reveal the lens and motor module. Flip over the model and you should see the gear and shaft for the lens. Move the gear so that the lens move towards the centre. Click the covers back into place , reconnect the battery and try. If it works, put all the screws back. Mine was fixed this way but this is not a gaurantee that this will work on yours. Good luck.

Thank you soooooooooooooo much after 4 years my DVD player is still working "well it is again now lol"

I was horrified when I kept getting the Hco3 code. Thank you and your daughter for your help.

My 3 year old thanks you from the bottom of her heart. Worked like a charm. Thanks

Thanks for the tip. I opened up the unit, moved the gear back to the center and it fired up like a charm. big halp thanks a bunch.

I moved the motor unit towards the center and tried the unit. It didn't work. I then moved the motor unit towards the outside. The unit then moved towards the middle of the device, but still didn't work. Did the same thing again, with a touch or Vaseline. That will be $125, works just fine. Awesome!
