Question about Hitachi 55HDT51 55 in. HD-Ready Plasma Television

1 Answer

Picture not to full screen

I have a Hitachi 55HDT51 that I recently moved. After hooking up the cable box, of the 55 inches of screen, the picture is only about 42 inches. I have tried every type of cable from box to AVC unit, I have set the settings properly on the cable box. I have taken the AVC for repair and they assure me nothing is wrong. When I unplugged everything and started again, I momentarily had almost a full screen with about 4 inches on right side of screen that had blue, red, pink lines; however, no sound! After trying to go through settings, the TV "switched" back to the smaller screen version. I have tried every aspect, etc. I have a suspicion I am missing something simple, but have no idea what to do next. Any suggestions? (Oh, the cable box DOES have DVR, is this possible issue?)

Re: Picture not to full screen

Try connecting just the cable to the TV and bypass the cable box. If you get a full screen and the "ASPECT" button on the remote gives you full operation then either you need to change the output on the cable box to 16:9 output at 1080i resolution (because it sounds like the box is putting out a 4:3 screen size)or in your customer menus on the TV, I believe there is a "AUTO ASPECT" selection? If there is and it is activated then turn hat off. Having DVR won't effect the screen size. It just means the cable box has a hard drive built in to it.

How do I unlock the setup options for horizontal & vertical adjustments on my 55" HDT 51M 2006 Plasma TV won't let me access the horizontal or vertical options in setup in RGB 1 mode.

You have to enter the service mode option to it, to do horizontal and vertical adjustments. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box.
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

When watching movies or football games the text/score is often off the edges of the screen. I have tried changing with the remote with the options cinema, panormaic 1, panoramic 2, full and zoom and 4:3...

The change actually has to be made with your cable/satellite service's remote control. On the cable remote you should have a #hd zoom button. On the satellite remote it may be format, aspect, or a setting within the menu. The cable/satellite box's menu will also have a setup section where you make sure the resolution is 16:9 1080i fixed. Make sure to disable the 4:3 override as well. Then you use the button on your tv remote to further adjust it with cinema, panoramic, full, or zoom.

Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)

I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.
