Question about Toshiba 57H81 57" Rear Projection Television

1 Answer

Toshiba 57H81 57in. Rear Projection Please help us get started

We just inherited this TV. No remote, no user's manual. We do not have cable box, just hook directly to TV. We have a horrible picture no matter what we hook up VCR, DVD, we do not get any TV pictures unless we do a PIP view and then we lose audio. The picture is jumpy, wavy, lines, you name it, it has it. I just need to know if we are hooking everything up right b4 we come to the conclusion that there is something wrong with it. We were told that nothing was wrong with it except the green bar and that only affected the color.

Toshiba 51H84 Television Questions

I'll try to respond to the questions in order;

1) This unit requires a converter. It only has an NTSC tuner not ATSC.
2) The remote will not control the converter as the coverter is too new.

Your best bet for having a songle control for all devices is to purchase a universal remote that will control the converter. I am not aware of one, but must admit that I have not really looked much. To control the number of devices you would like, the control will likely cost in the $10-$15 range.

Keep us posted,

Look up your user manual, it sounds like your zoom feature has been activated to the max. I have a Zenith backlit LCD TV and it has a zoom feature you control from your remote. You could open up your on screen menu and find the place to reset the TV to factory settings that should clear up the problem.

Screen went blank sound ok

Do yo have the remote? Do you have the manual? Manuals are usually available online.
If you are feeding the Toshiba with cable wiring then the problem is with the Toshiba. Maybe something as simple as the wrong input is selected on the remote control. If you are feeding the Toshiba with audio and video cables then the input to the Toshiba would be suspect. Either cabling (the inputs and outputs are plugged in wrong. If you changed anything I would retrace your steps.

Let me know by clicking on 'ask me' and if solved please do the rating. Thanks.

Toshiba theaterview 50in rear projection tv

Look at it on the QVC channel where you have boxes with straight lines. If any of the 3 colors are bowed and 1 inch off, then it needs parts inside. If the colors are straight and only 1/4 inch off, you can adjust it. Using the remote, in the menus find convergence to adjust. Your user manual will explain it. At you can download the manual if you do not have it.
