When the set powers up the vizio picture shows on screen but then when it fully powers up and I hit my uverse menu, I can see the very top but can't see anything or read anything below as it is all black with sometimes vertical "interference type" lines. The sticker in the back says Mfg date Oct 2010 serial LTNIBCL4200972

SOURCE: I have a Vizio LCD

Hi, vertical lines when the television is on may be related to issues with the television's screen resolution. Resolutions set higher than 1280 by 720 can create visual disturbances on the screen. You can reset the resolution through the control panel's display settings menu. This should correct the issue immediately, although you may need to power the television off and then on again in some cases..

I have a Vizio E320VL with a video problem.


The Tcon boar or the LCD panel is faulty. You have to replace the TCON board to confirm it.

Vizio e421va picture going black


POSSIBLY T-con pcb, but check the cables between the T-con & the panel & the cables between the t-con & main pcb.
Try unplugging & reconnecting those same cable links. When disconnected look at the condition of the cables & boards. your looking for signs of arcing or corrosion.

T652n 202.03 paperjam


1Open the upper-front cover and remove the toner cartridge.2
Look into the printer. Remove any jammed sheets of paper that you find there.

  • If the print job only consisted of this one page, reinstall the toner cartridge and close the front cover. Press the pattlnk_10162008_2247-select_button.jpg button to clear the error, and then try printing again.

  • If the print job consisted of more than one page, confirm the entire paper path is clear before printing again. Do the following:


    1. Remove the top paper tray ('Tray 1').
    2. Remove any jammed or partially-fed sheets of paper you find here, then reinstall the tray.
    3. Go around to the back of the machine and open the upper-rear cover. Remove any jammed sheets of paper you find, then close the cover.
    4. Once you have confirmed that the entire paper path is clear, reinstall the toner cartridge and close the front cover.
    5. Press the pattlnk_10162008_2247-select_button.jpg button to clear the error, and then try printing again.


  • If you cannot locate any jammed paper under the toner cartridge, then check the rest of the printer for any jammed paper. Do the following:

    • Remove the top paper tray ('Tray 1') and look for any jammed or partially-fed sheets of paper.
    • If you do not find any jammed pages there, reinstall the tray and go around to the back of the machine. Open the upper-rear cover and look there.
    • If the entire paper path appears to be clear, close the rear cover and power off the printer. Reinstall the toner cartridge and close the front cover. Power the printer back on. If a 200 error continues on power up, a sensor in the printer may be malfunctioning. This will require a service call to correct the issue. Please contact Lexmark Technical Support for additional information (see Contacting Lexmark Technical Supportbelow for details).

Screen is completely black except for about 4 inches on top......


Try a reset of the display device or hit the menu button to get a display on the screen- If you get a full picture that way then you have some setting set wrong. It could also be a PIP- picture in picture mode that you only have one source put into the TV rather than two.

My JVC model AV-20F476 has a black-out box that covers most of the bottom half of the screen.


Go into menu and under CLOSED CAPTIONS look to see if TEXT is engaged---if it is set to text 1 turn it off or to text 2,3,4, etc

Text was a feature never really used but it is there, some cable boxes also have this setting/feature.

Let me know if you have questions.
