LG 20LS7D flat panel LCD TV

A black box keeps popping up in the middle of the picture approximately 4" x 8". Changing channels will make it go away, but after a while the black box is back and it isn't on any particular channel. Any ideas?

Hi, go into your menu and turn off closed captioning, sometimes listed as "CC" instead of spelled out "closed captioning", this will fix ya, Happy Holidays, BMW Rider

I`m getting a black rectangular box in the middle of my LG LCD TV 42" bought about a year ago. This box doesnot disappear with changing channels. Appreciate your help in this matter

Sounds like you have a cluster of dead pixels.

If you're still within warranty, contact LG directly. If you purchased extended warranty, then contact the store you purchased it from.

This is generally not economically feasible to replace, but it is covered under warranty. If you're out of warranty, then you're most likely going to be shopping for a new TV.

Good luck.

Some channels on direct tv have a black rectangle

Either your tv or your directv receiver is on the text mode of the closed captioning function turn closed caption off and this will disappear.

Black box appears in middle of screen

go into the menu and look at the closed caption option----if TEXT is highlighted--this is your problem---select CC! or if it has it OFF.The TEXT will only appear on certain channels and it most likely was activated by someone changing the closed caption options. If this has been helpful give me a vote to let me know.

Black screen on a 20ls7d LCD TV

I work at CNN Have had 6 of these monitors go out in as many months. Take out the power supply and change the 2 exploded 680u capacitors. They're being overheated by the underrated MOSFETs on the reverse side of the board. I'm looking for some substitute MOSFETs that handle power better; but replacing the caps will usually fix the problem. Otherwise replace the supply.

Black square box pops up in the middle of tv screen.

It is most likely related to the Closed Captioning option on your TV. Go into settings and make sure that CC is turned off, or make sure it's set to CC1. What you are probably seeing is the "text" option included in the CC options.

Worth repairing, you need to replace the Y drive and Y sustain modules, parts about $300.
