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 Red Line

I had a bright red 1" wide vertical line on the right side of my Vizio P42HDE as well as an equivalent Green line on the left. Sometimes a Blue line would appear adjacent to the red line. Had this TV sinc Oct. 2005. Based on internet research, I opted to purchase an LG 6871QCH060Q board (upgrade to the 6871QCH038A and the 6871QCH038C). Picked the board up on Ebay for $100 + $10 shipping from ShopJimmy parts.

From start to finish, this took about 2 hours to repair. Tons of screws to remove. Took me a while to figure out that the video connection unit in the back is completely modular and needs to be removed before attempting to remove the back cover. Once the cover was removed, I was surprised that I could not see where the replacement board was located. Turns out, you have to go one level deeper and remove the audio board and digital board followed by metal bracket/cover. Once removing the metal cover, the bad 6871QCH038A board was visible. A couple of zip ties will need to be cut as well as several cable connections to get to the 6871QCH038A board. Replaced the board with the 6871QCH060Q upgrade. Make sure to keep the sticky foam rubber isolation pieces and adhere them to the new board. It did take some time to figure out how to disconnect and reconnect all the various types of cable connections. Just take your time. The power cable connector for the 6871QCH060Q board is in a different location, thus I had to reroute the cable. Reassembled and only had 2 unused screws left!

TV workd great. Lines are gone. Have a little burn-in going on where the red line appeared, but still better than forking over $800 for a new 42" LCD 1080P TV. Hope to get a couple of more years out of this Vizio.

One line I found has a general example of LG/Vizio repair manual. Not exact, but close enough...http://www.scribd.com/doc/7580885/LG-TV-Plasma-Training-Manual

Don't replace anything, Vizio has issued a lifetime warranty for this set because of this problem. No joke, call the customer service line and tell them you got the pop of death. They'll send someone out to 'repair' the set free of charge. If they can't fix it they'll give you a new one. Even if your mfg purchase warranty has expired. Call them and post the results. I've been fixing TV's longer than I care to admit and this is the first time I've actually seen a company stand behind their products like this. I bought a broken tv with the intent of fixing it and after replacing almost every board I could only manage to get the vertical racing stripe line, except mine was purple. I put it all back together and called to find out if there was a recall on this set and within 5 minutes the (Actual English speaking) gentleman told me to sit tight and he'd have a repairman come and do his thing. He did, and long story short, he couldn't fix it. Last week they delivered a new TV to replace this one. I was shocked. I think Vizio will have all my future business.
Good luck.

Hello ,

I would suggest checking the driver circuitry for the LCD screen and I would also check the connectors from the driver board to the LCD. Either a component has begun to malfunction (hence the excessive heat) or the component has becom thermally sensitive and is reacting to existing heat and is allowwing excessive current to pass causing more heat to be generated. In any event have a qualified TV technician look at this problem because he will have the proper equipment to troubleshoot the TV in the proper fashion.

Hi,
Your tv have problem with the T con board. T con board is one wich drives the pixels in the LCD panel. There is no repair possible with these boards. You have to replace the T con board.
