I have found a couple of sites where you can download the owners manual for a fee of $9.99 but I have been unable to find a site where it is free. Hitachi web site does have several owner manuals but do not have the one for this tv. My owners manual is a photo copy of the original
manual. I got mine by calling Hitachi (1-800-448-2244) shortly after purchasing the TV, it was a display model and did not come with one. I have just bought my second remote, first one when I got the owners manual and second one just a couple of weeks ago through sears parts. Once I get a scanner hooked up I will try to upload my manual to this site.
If you would like the service manual, go to http://www.schematicsforfree.com/archive/?path=Video%2FProducts
and scroll down to
this is the "service" manual for Hitachi models 46UX50B/51K, 50UX52B/53K, 60UX54B/55K, 50SBX70B, 60SBX72B, 70SBX74B. These are the same model numbers listed on the owners manual.
I hope this helps someone out. Shera
