Question about Hitachi 57F500 57" Rear Projection HDTV-Ready Television
Take it from someone who actually services Projection Televisions, excessive overscan is not a normal situation. If none of your service adjustments were changed, your PTV has a defect that needs to be checked out by an experienced technician, not some rip-off who will bring a computer out to your house and charge you 400 bucks for an alignment; that's a con, don't fall for it. Electronic parts get old, change value, go defective. Memory IC's that store data get corrupted, etc. A "calibration" should be the final stage in any repair that alters geometry or convergence, not an extra. It can take an hour or two if registers and values have to be adjusted, but is part of the job, for a servicing technician. Your captions should look pretty much like any direct view TV. Check for Hitachi warranty service centers near you. Never allow your TV to be serviced by anyone who doesn't have a storefront. Pay a little extra and get a qualified electronic tech, not someone who may do more damage than good!

Overscan is a staple in all CRT triple gun RPTV tech. It has to be taken in, if you want to see all of the picture possible in this medium. On ceiling mount front projection they have equipped them with all they need, they didn't need to do overscan, but with RPTVs this was not possible at the given price points. Overscan was necessary, to hide all the flaws out there at the edges, and they could not afford to pay their factory calibration techs to do it right, at the price points of the RPTV marketplace.
Unfortunately, when you take in that overscan, the picture gets hosed beyond belief, and then needs to be completely redone. It takes several hours and has quite a learning curve, a different one for each brand.
It is always available in my calibrations on all brands, but as an extra, at extra fees, to cover the extra time and experience/expertise required.
