Re: VIZIO M552i-B2
You are in luck! All you need to fix your set is:
1. Leaded solder
2. Solder sucker
Reflow the connector between the power board and the led driver board. I then remove the solder one at a time to get rid of the lead-free solder and then resolder for good.
Then I glue down the black connector to the power board. There are 2 rows of pins. Row 1 are all common and row 2 are all common, you could run a line across each row. Dont bridge row 1 to row 2.
I'll bet your connection looks like this picture.

Re: VIZIO M552i-B2
Current symptoms is tv presents with no picture. Screen does show back light although a bit dim IMO. When tv is booted the screen displays nothing but a glow at the center of the screen. No indications of sound. When I press menu on the remote I get a different back light pattern but nothing visual - not sure if I'm seeing a horrible display of menu section or back lighting pattern. I was looking to isolate and prove the t-con board vs the mb -main board vs lcd display. T-con board was replaced as a shot in the dark purchased from amazon. I do have 26v at backlight pannel and 12 at main board with 5 and 12 volts at t-conn. Remote functions as expected limited to no visual proof.
I need the wiring diagrams to test out components and not fire the parts cannon at the tv. I have the tools for component level repair, just need the data.Leave a comment:

VIZIO M552i-B2
Does anyone have any wiring diagrams for a VIZIO M552i-B2. I'm new and I spent 4 hours online, even signed up with a paid service and found BOOK SALES in the end. I did shoot through the sticky notes but didn't find anything that said wiring diagrams. Are they to be had or do I have to wait for the right to repair bill to be passed in calif?
Thanks for your response and welcome to the board!Tags: None

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED... -
by howardc64Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
by howardc64Bug looks like hardware so thought I posted it here. Exact same behavior on 2 different model 4K Vizio TVs running their SmartCast smarttv software. After launching youtube app, press vizio button on remote to return to the smarttv menu, once in awhile, a column of bad pixels will show for few seconds on the left hand side.
It seems the vizio software is reinitializing hardware when returning to the smarttv menu. In general, SmartCast software isn't very good. Also will randomly (relatively infrequent) get no network connection when on wifi and require reboot.... - Loading...
