I recently had the same problem. You need to contact Hitachi (1-800-448-2244) and advise them of the issue. Hitachi will give you a local service contact who will look at your TV and advise you that the light engine needs replacement. Afterwards, you need to call Hitachi back and speak with a customer service Rep. They replaced the part (I was quoted $530) but I had to pay labor and service (($370). If your TV is 12-18 months you should be able to get them to cover both. Based on the service rep that fixed mine, he indicated he has replaced about 40 of these since late 2007. Mine was replaced last week and now I have a different issue, a bright blue pixel light. Now it's round 2 with the service department. I have not been impressed with Hitachi's customer service considering I spent $3200 on this TV 3 years ago. Hope this helps. Good Luck!

You may want to find a service shop willing to troubleshoot the power supply vs replacing a $300+ part. Labor will still be a few hundred but parts would be minimal.

I found that since the Panasonic TH50PZ80U TV has only 2 HDMI ports on the back of the TV, the best solution for me was to use component (red, blue, green) cables to connect the Home Theatre to the TV. I suppose I/you could connect the home theatre to the HDMI port on the front panel, but I don't want cables hanging out the front of the TV (personal preference). Unfortunately, I am no longer able to use the VIERA Link functionality available by connecting all Panasonic components to each other using HDMI cables, but I feel it's a small price to pay for the incredible picture quality acheived by using the HDMI cable to connect the HD Cable Box to the TV. I may yet be able to control everything using the HD Cable Box remote, but I haven't gotten that far yet but I've got Comcast coming on Saturday and hopefully they can let me know if this is possible: let me know if you have a solution.
So here are the components and the cable types used to connect:
I hope this helps someone else.
