missing one of the two inner screens which are only sold in pairs.

Depending on how long you've had your T.V, these problems are usually lamp related.

Tries this website for a new remote 1-800-Remotes Factory original for new remote or tries the manual controls on the tv for functions to ajust the screeen sizes.

yes there is a fuse on the bottom left ( think that is whewre it is on this model) but as its near the HT it might be better to let the techs go there If they get eloectrocuted you just call an ambulance If you get fried someone may not find you for a wekk or two good luck

The HV circuit that runs the lamp is out
or the thermal fuse near the lamp is bad/blown.

You have a defective light engine. We just went through this and we have the same TV that you have. Hitachi knows about the problem but will play dumb when you first call. If you deal directly with their Customer Relations Department 800-654-7013, it will make a lot of difference than regular customer service.

Here's how they handled our situation. We called Hitachi after lots of research online and they gave us the names of some certified dealers in our area. The tech came out and in less than 1 minute said the TV had a defective light engine. We called Hitachi back and low and behold, they are aware of the problem...imagine that. Hitachi called the dealer directly and once the dealer confirmed the problem, they agreed to send a brand new light engine out to the dealer and the tech came out and replaced it. Here's the kicker...Hitachi will pay the for the part ($1500) but they ask you to pay for the install. Our install was $400. This was worth it to us being that we spent $3600 on this set 3 years ago. Once the light engine was replaced, the TV looked BRAND NEW! Please deal with their customer relations department at the number I lised above. If you deal with customer service, they will have you chasing your tail...so to speak! Good Luck! If you're willing to cover the install, the rest should go pretty smoothly..at least it did for us:)
