Re: how to get rid of a black screen on my tv. sound is...

If you mean that you get a black box, with a little of the picture visible around the edges, then your closed captions are on and set to TEXT. This puts a black box on the screen about 10 seconds after changing the channel. Go into the menu and turn off the closed captions and the picture will be back to normal.

Screen has black box with greek letters on channel

If you put the TV on CH 3 and use a VCR (if available) to change channels you'll know if it's the TV or cable channel (sound like the channel)

Big black box in the middle of the screen

The black box is there because your closed captioning is on and set to text mode. Some channels send the signal even when there is no actual text to display. You can get rid of it by either turning off closed captioning or changing it to CC1 or CC2 mode instead of text. If you can't find those settings, then restore factory settings as directed in your user manual.

you could be having some problems in the HT area. look for a burnt low value resister that is around the fly back transformer. the value of the resistor is marked by their color. so look and check the resisters that have gold on the third band of its color.
