Question about Westinghouse Televison & Video
I also have a smaller Westinghouse that I successfully upgraded the firmware on and would like to do the same to this TV. There's a USB service port but the Westinghouse site doesn't seem to have an upgrade available.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
click here to download the app (for users in the US for now) and get all the help you need.

This problem is caused from a problem with the main board. The main board will need to be replaced. It runs from $100.00 to $150.00.

If you are using the television with a cable box try looking a format button the the cable boxs remote to change aspect of the pictue. Also try unpluging the unit from the AC outlet for at least two minutes to reset the unit.

Testimonial: "Thank you for your help. Using the cable remote to fix the picture size problem did the trick."
the high pitched noise is probably coming from a transformer in the unit, which leads me to believe that there's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for 5 mins, then try.
If you aren't tech savvy, this unit needs to go in for repair.
If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering).
Most of the caps that go are 10V 1000uF or 3300uF.
I found some great videos of the procedure (for different brand, but same issue) on youtube.
As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.
