Hi - In a desperate attempt to find information on the H03 error message, I found you! I have a Panasonic portable DVD player LS50 that has this HO3 error message. We have only used this DVD once on a long 10 hour plane ride and now it won't work. It is less than a year old. According to Panasonic it needs to be sent in for repair. I called one of the service centers and they say it is a burned out laser and will cost $200 to repair. Unbelievable! I paid over $600 for this dang unit with all the extra batteries and converters we needed. Any help is appreciated. I will never buy another portable DVD player again! I'm furious that they can make such an expensive product that gives out so quickly. Thanks.
