Try unplugging the TV.. After you plug it back in it may be OK. I had a similar problem were I could not turn on the TV (JVC). The owners manual specified in the troubleshooting section to unplug for 1/2 hour. I left it unplugged overnight and the next day plugged it in and it was fine.
the black rectangle appears as soon as the channel indicator goes off. someone has turned on the closed captioning in the menu of the set. it is in the "text" mode. go into the menu and turn off the closed caption feature.
,,always unplug the set from AC,leave off a few minutes,,then re-plug back in,,that resets the micro--also,it could be the volume up button stuck-that would kill the other keys from working--you could try with a tooth pick to pull VOL UP back----THIS IS DANGEROUS --SHOCK HAZZARD!!! if someone is technically incline,with the back of the tv off,,turn set on and unplug the keyboard plug from the main circuit board while the set is playing--then use the remote and see if the fuctions returned-THIS IS DANGEROUS-SHOCK HAZARD---I REPEAT -DANGEROUS!!!! PLEASE BE CARFULL,if that cures the problem-you have a bad keyboard-you can just leave it unplugged and use the remote----JUST BE CARFULLLLLLL
Usually something wrong with the tact switches behind the
buttons on the front of the tv....Remove back of set...unplug
audio and degaussing and slide chassis back...check each
switch with meter......also, check buttons row..............T.
One thing you should not do with electronic devices which have a start up proceedure is to turn the power off, and then on again without a wait of about five minutes.
Some equipment manuals warn you about this, and specify a longer period.
The start-up has to have time to reset.
It will be more likely to reset if you do not leave it on standby,
and even unplug it.
In your TVs case you need to describe the distorted picture as it may give a clue to a fault, or incorrect start-up.
The horizontal line indicates the frame timebase had stopped working.
No picture could be a fuse blown inside the set, or a timed cutout which may reset after a time.
Try after several hours to see if it comes on.
If it is just the frame timebase (vertical) it is worth repairing.
