First off, I'd like to say thanks to everyone in the thread for guiding me to fixing my DVD player. It's much appreciated
I have a Panasonic LV50 portable player, and about a year ago it gave up the ghost with the H02 error. It went in a box and we moved house. Recently we planned a trip with our two children, and I realised I needed the LV50 working, so a quick Google found this site.
The symptoms were that the disc would spin, and the laser was working, but the screen stuck at Reading for a couple of minutes then everything stopped. I watched the action by holding down the small buttons on the right side, fooling the player into thinking the lid was closed. The pickup was moving back and forth, up and down and I could see the laser through the disc. Having a closer look I noticed that the pickup was about 7mm from the edge of the spinner. Thinking that it was looking for the disc header in the wrong place I opened the back (the three button initialise and the shaking hadn't helped at this stage).
Turning the unit on it's lid I removed the screws and gently prised up the panel. It was clipped in on the front edge with two small hooks, so a degree of BFI was required. The first thing that is evident when the unit is opened is that the three sections (the back panel, the front assembly and the reading unit) are all connected by thin ribbons. Once I had that I moved things very carefully and made sure not to extend the ribbons to breaking.
I saw the spindle arm - it's about 60mm long, and to the side of the lens mounting. I used my index finger to gently turn it until the lens unit was up against the end of its run. The drive unit sits with three rubber feet in metal holdling points of the front section; I gently placed these together as I reassembled the unit. Closed everything up, and powered on for a test.
After three or four seconds of anxiously waiting the DVD title kicked in, and I had a working unit again
I hope this description may help someone else with a broken LV50 (or similar). Thanks again to all who gave the advise which led me to this solution...
Take care, Ian
