Question about Televison & Video

1 Answer

I have 46" vizio model# M3D460SR. The whole screen has a light static and on the left hand side of the screen there are vertical lines going through it. I'm all able to look at tv but i heard if it's the panel then I'm pretty much SOL! Hopefully that's not the issue and i can get the tv repaired due to the fact i don't really have the budget to get a new tv at this time.

SOURCE: One green vertical line in HDTV Vizio 42

Try changing the H/V position in the TV Set Up menu. You can adjust the horizontal and vertical position of the screen and move it enough that the green line disappears from the screen.

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

SOURCE: Permanent Vertical Line on my Sony Bravia 46 inch LCD TV

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

SOURCE: 46 inch Sony flat panel lcd has vertical red and

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

I would suspect the backlight inverter is faulty:

I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the BN_on (on) the backlight inverter and you still have no picture...you will need a new inverter.

This could also be the CCFL bulbs that are aging and need replacement. Those are around $20 each for a bulb

Hope this helps! Please rate :)

The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.
