Originally, I was trying to solve a flickering issue with my TV. There was a significant ripple on Vs and Va, so I decided to check all major capacitors on all boards. After de-soldering, testing, and re-soldering all major capacitors in my TV, it no longer powers up. When power is applied, the main board has one red LED on the left side lit, and 4 on the right blinking down in succession. (ex. 1, 2, 3, 4, 1, 2, ...). The TV does not respond to the remote control or the front panel buttons. The standby light does not turn on, and no relays click. Does anyone know what this could mean?

Re: Zenith P50W26 not powering on
Resolved. There was a "hidden" button to the right of all the video inputs from the back. When re-assembling the TV, I had thought the hole was a screw hole, and ended up pushing the button with a screw (it didn't fit the hole so I took it back out). Pushing it again brought the TV back to life. I really wish I knew what that button did now!
