20 Most Recent Toshiba 42LX177 42 in. LCD HDTV Questions & Answers

Its a failing LCD driver, not a lot you can do about it unfortunately, eventually it will get worse. Usually lines or dots are a bad driver board, but sometimes its also a bad flex cable on the LCD. Being 2 years old you probably don't have warranty, but if you do have extended warranty file a claim now, its only going to get worse, and there is no quick or easy fix.

I had the same issue... here's what I did.  If power off your cable box, then press the menu button, there's a selection to enable or disable Closed Captioning.  This works for both HD series Motorola boxes Comcast offers, at least in the Minneapolis/St. Paul area.  Hope this helps!

You have to activate the closed caption option on your charter cable box. Power off your cable box and immediately push the menu button. A menu should appear where you can toggle captioning on/off. Good luck!

if the comcast box is not hd then the control is with your tv/remote.
If the comcast box is hd, then you can control it from the comcast remote. To do this press cable, then power and in 2 seconds press menu to get to the hidden hd setup menu, scroll down to closed captions and set it to enabled or disabled then press power twice to get back to you rtv

Same issue here. I kept plugging in the TV and it would flash the logo and go black. I disconnected the LED line from the power board, plugged the TV back in and the LED's all lite up and got great picture. Turned it off and on a few times with the power switch with no problem. Left it alone about an hour, came back, got the same symptoms all over again, Flash then nothing.

I changed out the Power Supply board....same issue, Flash of logo and black screen. Probably going to heave ho the set.

You might have gotten a magnet close to it but you can't fix it if you did that
