A little over a year ago, my Westinghouse 22w3 stopped functioning. Initially, the screen started acting, but shortly after, it stopped powering on at all. I finally got around to replacing the capacitors on the board a couple of months ago. The monitor worked correctly for a month before it stopped powering on again. The caps look fine and I can't imagine them going bad already so I'm looking for any suggestions for what the issue could be.

Thanks!
