Re: Vizio M50-C1 no picture
I took the outer cover off and these are what I found. Is this what I'm looking for? Two different boards and are attached to the panel on numerous ribbon cables.Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: Vizio M50-C1 no picture
those are the bottom boards. You need to find out what on the sides... you need to remove the bezel to look at that area.Comment

Re: Vizio M50-C1 no picture
I removed the front trim bezel and there are no boards on either side of the tv that I can see. You can see in the picture of me pulling the screen away from the set. The other pic is showing the spot on the screen that is causing the issue. Looks like maybe something inside the panel exploded?Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: Vizio M50-C1 no picture
I see the screen is made by TPV. Here is a picture of the info. What is the model number? I was going to do a quick search to see if I could find a good used panel before threw the TV away.Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: Vizio M50-C1 no picture
I am sorry, this won't be repairable.
That is some physical damage, possibly from a short inside the panel.
That's why I suggested earlier to turn the tv on without tcon, that way you would have been able to see that defect, and could spare yourself from disassembling the set. At this point, you would need a great luck to find a tv with bad backlight/electronics with the same (but working) display.
I would sell the boards and get a few dollars back for my lost time.
Edit: On your last picture, the display type is hidden under the black plastic, ends with U01, but I can't figure out the first few letters/numbers.Last edited by yohnsee; 09-13-2018, 11:51 AM.Cheers, JanosComment

Re: Vizio M50-C1 no picture
No worries I kinda figured it was a goner. You couldn't see the damage to the screen until I removed the plastic bezel. It was hidden underneath.Comment

Re: Vizio M50-C1 no picture
Does anyone have schematics for any of the boards in the Vizio M50-C1? I have a "no picture" issue, which seems to be common. However, in my case the display never seems to come on. I can see a blue-ish LED on located on just behind the Ethernet connector. Checking power on the power supply board seems to show some odd values. On CN9101 when the power is expected to be off seem to have 5v as expected, but the 12v lines are reading around 19.1. That seems to suggest PS board issue, but I'm not convinced yet.
Thoughts?Comment

Hi,
I have a VIZIO E70-E3.
Symptoms: Black screen, no picture, but LED backlights are working.
I probed the power board and voltages are as listed on the board.
Main board appears fine, too.
I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
There are two separate ribbon cables feeding the LCD.
If both are connected, the screen is black.
If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and... -
Hi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted... -
Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright... -
HI all,
hope someone point to the possible issue before I start buying replacement parts.
Tv starts normal and responds to remote fine, PSU voltages mesured fine 19v was 18.9V under load and 19V with main board disconnected.
Backlight stays on all the time,
Sound works fine.
screen keeps changing form black to full picture in about 1sec intervals.
Picture looks fine with no visible artifacts.
I have disconnected backlights and flashlight test confirmed that picture is still doing the same.
Disconnecting left and right ribbons on... -
Hello,
Help is much appreciated as I don't have any experience with this model TV.
Picked it up and it was smoking in the back when powered.
Open opening the LED Driver board was charred (see last photo.)
I noticed some blown caps on the Power board as well.
Replaced the LED driver board, and bad caps on Power supply.
Voltages on CN301 (upper power supply connector to LED driver board)
X000017 - All 24.39V
GND - 0.001
OD - 0.015
VSNS - 0.009 (does that imply bad backlight or bad LED Driver?)
