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!

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 flicker

Mods, even though this is technically a monitor, it's more like a plasma TV. Do you think this would do better moved to the TVs forum?

Hello. I recently got an old Zenith P50W26 50" plasma display (10+ years, ~7000 hours used). It's technically not a TV. Anyway, it still works well, there are no problems with the image, but the entire display flickers like an old CRT monitor. The kind of flicker you can see better out of the corner of your eye. I notice it a lot more than other people I've asked. The flicker is much more noticeable on slow motion video which I can upload if anyone asks. This flicker is more apparent on brighter scenes and is independent of video source.

Va and Vs seem normal with a multimeter,...
