HI everyone Pick up this 55" VIZIO tv that only plays in black and white picture doesn't matter what inputs HDMI or apps, but all the menus are in color, if you're on Netflix everything in color until you play any show. I'm thinking main board if so, can the board be reflowed to try and correct this?

Re: vizio M3D550KDE Black & white picture

Re: vizio M3D550KDE Black & white picture
I think so, seems like a mainboard issue, not sure exactly where on board tho.Comment

Re: vizio M3D550KDE Black & white picture
hmm... press the picture mode button on the TV remote and go through all of them settings. Some report having luck just by flashing the latest firmware on it and fixing the issue. check the hdmi ports on the main board.Last edited by CapLeaker; 12-30-2022, 08:51 PM.Comment

Re: vizio M3D550KDE Black & white picture
Would an HDMI IC affect in-app video playback as well?
OP says it doesn't matter what the source is.
At first glance I figured its the BGA IC on the mainboard. Ive read somewhere how a visible degradation of picture quality when it comes to to perform high resolution video playback is one symptom that the BGA IC is having issues.Comment

Re: vizio M3D550KDE Black & white picture
It's a known issue, it's unlikely to be the same BGA ball(s) cracking every time, leaving the menus in colour but the video in B&W.
With a minimal description of testing and no photo of the mainboard it was an educated guess. If Netflix is through the app and not HDMI then I guess it isn't the HDMI IC.Comment

Re: vizio M3D550KDE Black & white picture
Yes Netflix thru the app and any app on the TV is in color you can scroll through the menu apps in color but as soon as you play a program it turns to black and whiteComment

I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
Hello,
Asus rog strix scar 17 G733QR
My Asus laptop started flickering from time to time and more and more in last months. First the screen was going black but sometimes if I moved the screen it would work again, other times I needed to plug/unplug the laptop or close and open the lid to make it work again.
In last days I see that if I move the laptop lid to about 45 degrees it will flicker or get white or black screen(it's random, sometimes white sometimes flickers etc). I was trying to troubleshoot it myself but seems like it's either the cable or the display....10-24-2023, 09:39 AM -
I replaced the backlights all good. Two months later set was dead, had a shorted D9100, replaced all good again.
Now months later set powers up,backlights light ok,no picture. 12volts missing from fuse on tcon. 12VA on power
supply is 19 volts. Changed D9100 again, same, 12 volts measures 19. Am I looking at a power supply or mainboard
issue. Set will power up with remote but not power off.... -
So I have a Vizio M3d550kde around 2011 per date on a sub board. The tv works well except that the input on HDMI inputs 1-4 are all displayed in black and white - (other inputs not tested and unknown if they are good or not.) -where the menu selection and initiation screen show full fine color. I was thinking ok fine Main board replacement, but then I thought wait a minute, the menu display comes from the Main board. Any thoughts or suggestion for repair?
I did a factory reset just to make sure someone didn't change a setting that would allow this weird behavior from the tv.
