Re: green lines through out the screen

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Try a "hard reset" first by unplugging the set for 30 seconds. and if no help, you may have a problem with the SMPS power supply, it might have a bad capacitor or two by now. Worth repair if engine is good compared to a flat panel.

Regular TV, you mean by the aerial and internal tuner, if it is like that, then it is a problem with the TV tuner board.
If by regular TV you mean an external TV box, then the TV box is faulty or you have a cable or ferquency problem.

Green Plaid Screen

Are you able to access the on-screen menus (like brightness/contrast etc)?

If those menus are appearing over the green screen, then it might be a cable or image source problem. I've often seen this green screen when the HDMI encryption between my cable box and my TV gets messed up. Only solution has been to power cycle the cable box.

If you can use something other than an HDMI cable to connect your TV to your picture source, I suggest trying that and seeing if you can get SD channels again. If you do get them back, it was a cable issue. If you still can't get them, contact your cable/satellite provider, see if there's something up with their signal.

Green tint to picture when dvi cable is connected

The tv will show correctly in 720p mode. Cable box and PS3 must be set to display in 720p or the green tint will remain. For the PS3 I return it to 1080p when I am about to play a game, blu-rays and dvd's can only play in 720p.

First of all, is your blue "HD" light lit up on the front of your Uverse box?

If yes, then you're in HD

If No, you need to check your connections from Box to TV
1.Those Red-Blue-Green cables are for video only, they don't carry sound and shouldn't be connected to audio outs. Audio needs a seperate cable. Make sure your Red isn't on the audio out which is also red. Make sure your blue and green aren't switched with each other either. Check that at both ends.
2. Try an HDMI cable. It will carry audio and video together and it's one cord instead of 5.
3. What brand/model of TV is it? Is it an older projection TV? The HD tuner might be shot. The individual color tubes commonly fail after a few years.
4. Are you selecting 720p or 1080i from your TV's menu or from the Uverse menu? You'll need to set it through the Uverse box, not the TV.
5.Follow -Menu -Settings -Aspect Ratio to change to 720 or 1080. This should start an autotest which will scramble your picture for about 5 seconds, then bring you back to a menu asking you to keep settings or revert back settings. If you never see that question pop up, then your TV isn't supporting the HD, and you settings will be rolled back automatically. If the question does pop up and you can read it, select "keep settings" and press OK. Your blue HD light should come on the front of the box now.

Toshiba 46In HD Rear projection TV Vertical lines on screen

We also have vertical lines with our JVC 62"... turning it off and letting it cool down is the only solution. For us, we know it's a problem with heat. We simply are wits end on fixing it. added two additional fans, a exterior fan to blow heat away from the back of the tv, pulled everything else away, etc.... Anyway, goodluck.

Sony 57 Inch XBR 2001

I don't have the XBR, but on my sony, using the cable box remote, I had to go into menu/display/etc. and mark the 1080i, 720p, and 480i settings. you usually get a "if you can see this" comment if your tv accepts the settings. for standard tv i set the screen to normal, and when the upper channels go to HD, they auto go to full screen. Sounds like you are using the component cable, and also make sure you are on the video port of remote, and the the TV input. The above worked for mine. Hope it helps.
