. unable to lower or raise volume, comcast remote on olivia tv


Open the thing up and clean off all the dirt on the volume buttons with a dry rag and clean the remote sensor.  Put in fresh batteries and now give it a try.

I raise the volume and a few minutes later the volume lowers by itself. u see the volume bar appear and the volume gradually lowering like if some one were doing it by remote


Without knowing the model number it's hard to say. However, it's not uncommon to have a defective switch on the actual TV itself. Try pressing the switches on the TV and make sure that they 'snap' in and back out when they are pressed.

I would like to order an owners manual and remote


Hello,
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 01-21-08 29842400 pdf.gif Hitachi 46Ux50B.pdf
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
