Zenith Flat panel TVs usually only have two boards in them Plasmas have a few more, doing a
visual inspection of the power supply capacitors usually reveals swollen
or bulging capacitors.
If the capacitors look good, voltage checks would be needed to isolate
the problem to either the main board or power supply. Check for 5 volts
to the IR board (& or keyboard) , if five volts is present suspect
the main board
If this TV has voltages from power supply , suspect the Z, X and buffers

Any time a TV is totally dead that is due to one of two boards except when they're both in one (which is becoming more common with time).
Those are the power supply board and the main board.
In case of Zenith z50pg10 it is usually the power supply and not the main board. It is possible to be the main, but it is not likely, statistically speaking.
Here's a link to the power:

I had a similar problem with my 42 in Philips LCD HDTV. Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems. Here are some options for you. 1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?) 2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though. 3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourself it will save you hundreds. This may be your problem. If you determine that it might be. I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help. Hope this helps and if it does please rate it accordingly. Good luck.
