How do I fix a black screen with audio still working?

You might want to check the VIZIO website for help. Given how cheap even 4K UHD TV's are today, probably not worth fixing again. Unless under warranty, of course.

Sounds like the fl tube inverter board power is failing. All flat panel screens us thin fluorescent tubes to light the edges of the screen, and when the tubes fail either from age or due to a power issue the screen will go black.

I think I may finally have the answer for the "black screen of death" for the 42" Polaroid LCD televisions. I was having the same issue with the screen going black after a couple minutes of being on. I would shut it down then turn it back on and it would work again for 5-10 minutes. On the "power board" which is the board on top, there is a little red light that turns on when the screen would go black. above that there are 4 little switches, the lower on says BURN. I simply switched that over and the television has been working for 2 days for 8 hours + each day. Hope this help. Let me know
