I find the manual. But I didn't find it so my bet is since you own this you have the manual. Look for any and all resets and try the defaults. I read you did resets but I'd check the product manual again.
After that tell more about the connections. This 720P TV is old but looks OK for use in today's systems.
HOWEVER I would only hook it up with HDMI.
Toshiba TV Model # 37AV502R Probably 2009 vintage. Dish satellite. For the past month the picture is cut off so text is cut off at the ends as well as at the bottom or top of the screen. i.e. the picture doesn't fit in the screen. I've tried various formats and all the adjustments I can find on the remotes and reset the remote and TV to factory defaults. I don't know if it happens with the DVR input as I have no disks with text and don't know if there's stuff on the edges I 'm missing. On some scenes it appears there should be more.
Is there a way I can isolate which device is faulty? Is there an adjustment I can make to correct? Any other thoughts?
