Question about Vizio P2 42 in. HD-Ready Plasma Television
I have a Vizio Model 42HDE TV. It has a bright vertical red line about an inch wide, on the right hand side of the screen. It occurs on all inputs and channels. Does anyone know what causes this? Thanks.
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

It is very likely you have a bad display. One way to confirm this is pull up the menu and see if the red line is on top of the menu or not. If the red line is on top of the menu the display is almost certainly the cause. If the red line is underneath the onscreen display you likely have a bad logic board.

Spoke with PartStore.com, rep stated 6871QCH038C (038C) is the superceded replacement for the defective prone OEM 6871QCH038A (038A). They and others offer the 6781QCH060Q (060Q) for $50 - $100 more. I opted for the 038C, but I was concerned about the title of the part which states "HAND INSERT"... PartStore.com rep stated it is in fact a board and there is no soldering needed, just "plug and play". DONE, paid only $120.95 + next day shipping for $29.95.
Since I took the TV apart before, it was a breeze and took about 2 hours, start to finish.
Important note, remember to remove the two 1" square spunge type heat sinks/pads the new board needs those for a proper installation and protection of the certain component.
Also you need two small zip ties to replace the ones you are going to clip off.
Added Bonus, the new board fixed other issues:
1. At times I would get a squeegly red line go across the screen. I thought it was the source (cable) but it is gone now.
2. Screen Shift, when I use the XBox for Games or DVD/HDVD the screen would shift. Very annoying, prior to swap out, recently the screen started to shift watching cable. Now it is no-longer an issue.
I am really pleased with my DIY repair and wanted to share.
The damn Vizio Out of Warranty Service wanted $360 for a service call which included the part for $125 plus they take my bad board for exchange.

I have a VIZIO P42HD as well. It was manufactured in 2004 and has a serial number of DTPBBT AE501351. I started with a red verticle line on the right side of the screen. This eventually led to a green vertical line on the left side and finally ended with the left half of the picture going out. I followed the "Best Solution" at the top of this thread, including ordering the part overnight from PARTSTORE.com. I ordered part #6871QCH038C as well. The part actually says its for an LG so I was a little worried. I called VIZIO and they could not give advice since I was dismantling the TV, but I went for it anyway. Low and behold, when I took it apart the PCB assembly was made by LG even though it was a VIZIO TV.
I took the TV apart, replaced the PCB assembly and it all worked flawlessly. Total time was about one hour. I have ZERO experience with TV's and was very impressed at how well it all went together.

I did have 1 inch black line starting from top to midle of screen.I talk with visio without any result. I did open tv (pd42hd SP42A type). I carefuly open flex connection when screen connect to pcb where black 1" band show. On one connection there are three square chips. Each of them have e big smt resistor. From hot solderin on resistor was fragile. After I resolder this resistor 1" black band went way.Hope this will help.
