could be a loose ribbon cable on a buffer board, or one of the buffer could be going bad

This problem is usually the ribbon cable connection at the top of the stripe. Reseat the cable first. The other possibility is the panel itself, but that is rare.
Keep us posted.

SOURCE: vertical red line on my Vizio plasma

Spent 3 hours removing all what seemed like 100 freaken screws.

Took out the OEM 038A, caution the factory placed some type of heat transfer silicon clear grease on the back of the board so it will feel like it is glued on. Just be very carefull and gentle when prying it apart.

Be warned, you will need a magnifying glas to check those little resistors. They all checked out, no broken solders.

What I did observe is the grease melted down the back of the board and puddled at the bottom of the board and where the resistors sit.

I used rubbing alcohol to clean it all up but left the reside on the square pads. Cleaned the resistors and used a dry paint brush to dust of any lint.

Placed the component back and after 10 minutes the Vertical Red Line Disappeared.

Turned on the set next morning it was still gone. 10 minutes later it re-appeared for a couple of minutes then went away.

I spoke to a kind gentlemen at Electronica-USA.com, he stated that the 060Q is an upgrade to the defective proned 038A ( 038C is also an upgrade ). A tech in Cali stated the 060Q worked perfectly. He has had zero complaints about the 060Q in the Vizio plus he offers a 90 day return policy. Funny thing is the 060Q was designed for LG and Goldstar Plasmas but for some reason they do not work for them but do work for Vizio's. He even states that on his site.

As I type the red line is still gone and stayed off several hours last night.

I think I am going to pull the trigger and replace the 038A to the 060Q and be done with it.

Oh yeah, I asked him if the 060Q needs to be "flashed" with the Vizio program. He never heard of it requiring it.

He has 038C on order they are couple of bucks cheaper. the 060Q is $224 plus S&H.

I found on ebay for $184 free shipping but waiting for the guy to verify no "flash" requirement.

Hope this helps someone.

Merry Christmas and a Happy New Year!

P.S. use a power screwdriver, your wrist will thank you. I put mine on low torque as not to strip the heads.

SOURCE: Vertical black bar down the middle of hitachi plasma tv

The tv is shot. This occurs when pixels on the top row of the screen break, which blocks current from moving through the rest of the pixels in that column. But don't worry this problem is common and is covered in your tv's warranty.

You could have one of three problems. One is really expensive to fix and you might want to trash the set. Thats if the panel is bad. Secondly, it could be a buffer board that went bad. Not as expensive as the panel. Finally, it could be the connection between the two. I would first take the back off and locate this board. Undo the ribbon cable2_bing.gif and clean it off a bit and put it back. If its still there, you have a deeper problem.

The buffer boards are located across the bottow when you take the back off. About 3 inches wide. Sometimes they are on the top as well.

SOURCE: i have an lg 42inch plasma and now a vertical blac...

I had the same problem with a five year old 50" LG Plasma. I fixed the problem with a 11 dollar soldering iron from Radio Shack and about 2 hours of my night. You have to open the back of the tv and locate where the ribbon strips are attached to the screen. I beleive that on your 42" they will be on the bottom of the tv. Mine had 11 on top and 11 on bottom. Yours will probably have around 7 or 8 along the bottom. Mine was a little easier since I did not have to remove the control board. You unfortunately probably will have to remove it. It is not hard at all, just takes more time. Make sure to keep your screws seperated and remember where everything goes. On bigger jobs some tape and a marker are very useful. Put tape on the board and around the wires removed and leave a tail. This way tou will remember to hook them all back up. Once you find the ribbon strips you have to remove them one by one and look at what is behind the metal place. There will be 4 capacitors and 4 resistors. The tv manufacturers want you to buy new tv's every 5 to 10 years so they use a very cheap solder on their contacts. Use you soldering iron and re-heat the solder to liquify it again and thats it. Allow time to cool on each of the caps and resistors. It took me about 1 to 2 seconds on each side of these parts. I did use a dual wattage soldering iron from radio shack. Its is a 25 and 35 watt iron. I used the higher setting. I have pictures if you would like me to email them to you and show you what I did. Be careful removing the ribbon strips, I broke one of the clips that hold in the ribbon strip. That is costing me an extra 25 dollars off ebay but still for a free tv, its not bad.

This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.
