Question about Vizio m420nv 42 in. LCD HDTV

1 Answer

Does anyone have any suggestions on how to fix this vertical gray line in my 42in Vizio tv?

I have a Vizio M420NV tv that I bought 2 years ago. A little over a year after purchase this 7in wide vertical gray line appeared. It has always been wide and has never gone away. I've managed to deal with it because I do not want to get rid of the tv. Outside of having this line appear the tv works great and is a good buy overall. However, it is now becoming a headache when watching tv and I hope there is some way this can be fixed. I read a few posts about replacing the logic board. If you think that is the case for my tv, is that something that can be done at home or do I have to take it to a repair shop? http://i1210.photobucket.com/albums/cc404/fcampbell78/Vizioverticalgrayline.jpg

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: LCD tv Vizio 42 inch has vertical colored lines

hello imvega7, as i know, 42 inch is a plasma display TV.
Refer to your image, and my experience that symptomp because of connection between buffer PCB and panel. Some cases, dirty conection may cause this symptomp.
Un plug power cord, open rear cover, fine pcb on upper or lower panel.
unplug flat cables from pcb buffer, clean soket using a brush. And also clean flat cables using celaner or alcohol.
Wait untill that conection dry. reassembly and try it.
i hope that help you.

For sure a defect. You are looking at a T-con board that is faulty. Return immediately and get a different one. If it's within 30 days just swap out and avoid having to wait for a warranty repair!

Vertical red line on my Vizio plasma


If the line is horizontal then it could be a y-drive panel ( depending on from ctr where it is ) whether it is the upper or lower board. Time to let a service company look at it, don't wait, more damage is possible the longer you play it.If it goes vertical ( up & down ) then it could be one of two buffer boards.
