Panasonic DVD-LS55 Portable DVD Player with 7-Inch Widescreen LCD
HO3 Success Story
After 16 months, I finally received the H03 message two days ago.  I considered all fixes recommended on this site and others.  Manually spinning the disc worked once, but the message reappeared.  Re-initialization did not work.  Ultimately, I needed to open the machine.  I was surprised to find a lot of dog hair inside the machine, and I imagine there was a lot of other dirt/dust inside the machine that was not visible.  After spending ten minutes cleaning the insides (using a tweezer), the machine now works again perfectly.  I think that, in my case, the H03 message was caused simply by the accumulation of dog hair/dirt/dust inside the machine. <br /> <br />If this wasn't a great gadget, I wouldn't have bothered trying to fix it.  Hopefully, it will work for another 16 months.
