Video problem. Lower 3/4 of screen flickers off and on with a "blacker than normal" screen. Works well for a few minutes, then black shading occurs off and on. Within black shaded area, screen image freezes momentarily.

You may already have tried the brightness setting fix, if not read here. Your Vizio could also be going bad. Sorry! https://www.techwalla.com/articles/vizio-tv-flicker

Your windows 7 screen resolution is set too high and your display doesn't support it. There are 3 possible solutions to this problem:
1. Press F8 during startup and choose "Enable row-resolution video"
2. Press F8 during startup and choose "Safe mode" and change screen resolution there, then reboot.
3. You can always use another display (if you have one) to set screen resolution to lower value.

Good day sir Alfred!!!!

If your screen turns to back after a minutes but the sounds is normal..That problem is very common to all flat panel specially to LCD TV..

OK,I need to know first if your TV having a back-light when the picture went out after a minutes.If that so the possible problem is T-CON board (this board is the responsible to produce a video on all LCD TV)..

If you don't have back-light the problem is inverter board again..But before you order or install new inverter board try to find why the inverter board gone only on few weeks after you install it..the possible problem why the inverter board faulty for the short period of time is higher/lower input voltages (24vdc) comes from power supply..try to check it using volt meter or multimeter tester..it should be read 24vdc on meter..let me know if the voltage drop or higher to 24..

If the 24vdc is fine the only problem is the condition of inverter board maybe its used or partially faulty when you buy it..

if you have more queries and clarification regarding my solution please feel free to reply on this tread...

Hope it helps..

Thanks for using fixya..
