Debbie, According to the forum below, the power supply board contains the high voltage inverters, the biggest load on the power supply and will be the faulty power supply board that's causing the screeching and shutting down. There was also a recall on your model a few years ago. Check the attached links,instruction and guides, Good luck

I hope this helped you out, if so let me know by pressing the helpful button.

My Vizio E601i-A3 suffered the exact same problem "Loud noise, then TV shuts down" but replacing the power board did not fixed it. Replacing the Main Board solved my problem. I found this note after on shopjimmy.com which actually discussed my symptoms.

Vizio Y8385864S (01-60CAP001-00) Main Board (SEE NOTE!)

This part is compatible with all versions of E601i-A3 and E601i-A3E

This board may or may not have connectors at location CN13 and CN24. 01-60CAP001-00 and 864 is found on sticker.

IMPORTANT: If your TV has No Picture/No Video, this is likely caused by a bad T-con board, and NOT a bad main board.

Symptoms commonly caused by a bad main board in this model include

-No sound

-Loud noise, then TV shuts down

-HDMI inputs non-functional

-TV will not tune channels

-No internet connection

-Internet apps open and TV locks up

Just had the same issue. After a while the TV would shut off and I'd get a high pitch squeal or a static noise. I replaced the power board first and that did not correct the issue. Replaced the main board and that fixed it. So if you TV is experiencing the same you may want to start with the main board.
