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.

Your TV displays the closed captions that are broadcast with some
television shows. These captions are usually subtitles for the hearing
impaired or language translations. All VCRs record the closed caption
signal and most pre-recorded commercial video tapes provide closed
captions. Check for the closed caption symbol in your television
schedule and on the tape's packaging: .
1 Press MENU repeatedly until you see the Setup menu. Press CH
to select "Caption."
2 Press VOL+ to open the Closed Caption menu.
3 Press VOL + to turn closed captioning on.
Misspellings and odd characters can occur in captioning. Also, there may be a
captioning delay after changing channels. Neither situation is a TV malfunction.
4 Press CH to highlight "Mode." Press - VOL or VOL + to choose
"Capt." (captions) or "Text." In caption mode, captions appear and
cover a small portion of the picture. In text mode, information unrelated
to the program, such as news reports, are displayed and
often cover a large portion of the screen.
5 If you wish, use CH , CH , or VOL + to change the captioning
channel or field. Then, press DISPLAY to return to normal viewing.
Different channels and fields display different information, such as additional
languages or supplemental information
