I have a very bad vertical line going fro the top to the bottom of the screen on my 32" Sanyo VizonLCD TV. This is the second time in a year this has happened and I had to get Sanyo to replace the first one.

Re: Here we go again
The problem is in the LCD panel itself. I am an authorized tech for Sanyo, and in the Chattanooga TN
area. Contact Sanyo at 1-800-877-5036. At the prompt hit the 0 key, and
then ask for customer service. They will be more then happy to assist.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
I have a Sanyo DP42746 model, 42". From my research I believe the lines in the picture are letting you know your Buffer Board is about to go out. Mine recently cut out, and it caused horizontal lines to appear. Hope this helps : /
If it is the vertical lines from top to bottom, more likely will be bad LCD panel. Try opening the back and place the small fan to cool down the TV to see if the problem will go away. The bad panel usually it will get worst with more line appears as time goes by.
It seems to be a PSU (Power Supply Unit) problem. When you unplug it and replug, the screen comes on for a moment. That means that the capacitor does not hold charge for long.
Open the back and look for bulged or burst capacitors on the module where the power cord meets inside. Replace the whole module if you can not replace the capacitor with exactly the same specs.
Both sound like bad LCD panels. The following must be answered to confirm this: Do the lines appear on all inputs/all signal sources? Can they be seen in the OSD/menu? If yes to both questions, it is likely that the LCD panel is bad
Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck
