I have a 32in element flat screen had for couple of months now tonight there is a black box in the middle of my screen what should i do

there are 2 capacitors on the power board that need replaced with exact replacements. They will be labeled ec17 and ec18 on the power board. The caps themselves will probably be brown or black and say 10uF 450v on them. You should be able to get the parts at radio shack or digikey or mouser. You will also need a solder gun and some solder. Check youtube on how to solder and always remember to unplug the TV before servicing.

check on the main menu for the text function and disable it

turn off close caption all the way in menu

becuzz u have de world ding daqts for folk dat caint here go to your azz in fucckc it goo there u go

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find.

turn closed caption off on tv & cable box

Turn off your Closed Caption, it's in text mode.

Make sure closed captioning is turned off on the TV as well as your cable box or satellite receiver (if you are using them and they have that feature). Captioning is probably on and set for text mode.

look for a button on the remote that says " cc " your closed captioning is turned on, probably in the text mode. turn off the close captioning and your black box will disappear.
