Hey if that's the correct part for $9 - it's a great deal
If not - I'll sell you mine for what I paid (you can see my eBay history) he wanted $30 plus shipping ($13.84). Not looking for a profit - just trying to help out another member

Re: Vizio m550nv "2 seconds to black" issue
Hello
Well I'm not sure if that part is correct or not but I do have the actual led bars (I bought 2 sets ). The other set I have listed in eBay if you need them
Anyways
I just removed the bezel and all the surrounding tabs. Best to work on a flat space with plenty of room
Once you have it all stripped down you will need to start removing layer after layer of panels.
I used printer paper to slide between to help separate. I also only touched the paper so no finger prints...Leave a comment:

Bars came today. Disassembled literally the entire tv. Powered it on. Works. Thanks everyone
I really hope I never have to do this againLast edited by Aceofspades16; 11-12-2016, 05:24 PM.Leave a comment:

Re: Vizio m550nv "2 seconds to black" issue
Good call. I'm looking forward to testing this again.
Ive forgotten just how heavy this 55" tv is and lugging it around the house quite the task.
Everyone - thank you for walking me though this...Leave a comment:

The frowny-face concerns me. Is removing those lights going to absolutely suck?...Leave a comment:

Re: Vizio m550nv "2 seconds to black" issue
Ok. I broke down the main board into 4 pictures. Tried to fill my whole viewfinder with the board then close ups of the board.
Also a snap of the "tcon"? Board and main board

Re: Vizio m550nv "2 seconds to black" issue
Thank you so much for the reply.
I'll be straight forward when I admit that I am struggling to identify what exact leads to test and what not.
I know it's required to post pictures so I will do that as soon as I get homeLeave a comment:

Vizio m550nv "2 seconds to black" issue
Hey everyone. As I stated in the welcome thread , I been a long time lurker. I joined today to finally ask a question of my own.
I searched everywhere and cannot find anyone with my current issue
On my tv, the led backlights suddenly went out. Still have sound and using a flashlight - still have picture.
The research I have done without any schematics for my set, was reading every possible scenario others have posted for this particular model tv. However no one had my exact issue.
So that leads me to believe my power board was to blame.
I tried another board... -
