I have a portable Panasonic LS-50, which is giving me the H03 error code. After I put a DVD in, it tries to read the disc, but the DVD definitely does not spin at all.
A web search shows that this may be a "Traverse servo error". I don't know anything about player innards, but it doesn't sound the same as the spindle problems that seem so common (and this model is relatively new). Of course, since the disc does not spin, it just might be the same thing. I haven't read any similar issues with Panasonic's portable units.
Would spindle replacement help at all? Or is the traverse servo something completely different?
