Black screen of death on a VIZIO LCD HDTC

My televsion tends to have the strange lines that begin to appear and in the matter of a few seconds or minutes the screen blacks out altogether. The sound is OK and when you switch to other channels or switch to a DVD it appears black as well. The TV is less than a year old. Any soloutions?

SOURCE: Black rectangle appears on screen

Check the settings for the CC (closed captioning) on your menu. Make sure it is turned off - if it is set to TEXT mode you will get a black box in the middle of the screen. Also look for a button on your remote labeled "CC"

Try resetting the TV. Here's how to do it - Unplug the TV's power cable. Keep the Channel Down and Volume Up buttons on the TV pressed and plug the power cable back into the outlet. You will hear a click when you plug it back in if the reset is successful. Hopefully this should restore your video and audio.

SOURCE: line accross top of the screen with flashing black and white boxes

Thin white dashes on top of screen is PERFECTLY NORMAL. It is nothing wrong with the TV, it is the broadcast. What you are seeing is the very bottom of the timecode running. It doesn't happen all of the time or all channels. It usually happens with old 4:3 commercials predating "Digital TV." This is mentioned in your Users Manual. You should be able to adjust the horizontal/vertical position in the menu settings.

SOURCE: TV No Picture

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

Vertical lines showing up after being on for awhile


Eh, I can't be too sure, but it sounds like it's either a heat issue, a signal issue, or a backlight issue. Either way, if it's still under warranty I'd send it in.

When I switch my tv to the HDMI input it appears to be normal for a few seconds but the screen stays black and I get a thin pink line running horizontally across the bottom right corner of the screen then...


You did not mention what you are connecting with HDMI but I have had problems with my PS3 and it is copy protection related. On a PS3, you have to connect it to HDMI1 otherwise some BlurRay movies will not play.
You might have a bad HDMI cable. I have heard the quality of cable does not matter these days but I still have had issues with the really cheap cables. I still do not buy the really expensive HDMI cables though.

Strange symbol on screen of my blackberry pearl


Generally rectangular box appears when you are in Roaming. After doing the Hardreset still if you are getting rectangular box in your handheld kindly walk into the nearest service center.
A hard reset involves physically removing the battery from the smartphone and then reinserting it. To perform a hard reset, complete the following steps:
1) Remove the battery cover from the back of the BlackBerry smartphone.
2) Remove the battery, and then reinsert it after a few seconds.
3) Replace the battery cover.
I hope I was able to help you.
Thank you for using Fixya.

Unwanted rectangular black area appears on screen blocking 40% of picture


This could be the result of a partly shorted vertical winding on the deflection yoak.Since the line is on an angle and not straight across.

Picture blinks in and out every few seconds


The lines in the picture and the blinking makes me think maybe the digital / logic board is going bad.. you will need a tech to resolve this and it will be expensive.. In time you will loss the picture altogether as the board will get worse.

Thick color lines on screen


Hi ,Sorry, this is not a solution. I have a question about your line. Is it transparent? (can you see through if the picture is bright)Does it remain there all the time if you change inputs? My LG 42" just had a blue transparent line appear on the right side of screen. Tried a few trouble shooting things w/ no change. About 1 hour later it went away. Did you find a solution and what was it?

Picture problem


Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.
