Panasonic DVD-LS50 7-Inch Portable DVD Player
Bad Product AND Service
Mine lasted for about 18 months before H03 reared its head.  Took it to my local customer 'service' center where it was examined by a man who apparently knew nothing about this error code, or indeed the player, at all.  Best he could offer was some comment about 18 months being the average life for such a product.  Outrageous!  And, then waffled on about there being no power coming from the battery, which is clearly untrue before finishing up with some useful advice about buying a new one.  It was at this point I picked up my 'dead' player and left.  I'll be trying the tips on this page but if I do have to buy a new player it certainly won't be from Panasonic.  Oh, and their wireless 'surround' headphones are useless as well!
