I have a Panasonic TC-P46-C2 that when powered on I hear the relays click but the TV doesn't power on. The LED gives a single blink code. What does that indicate the system sees as a fault?
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Blinking codes details to many popular brand TVs are given. Surf the site with patience.
On that site all the info for my model TV doesn't give a description of what one blink indicates. It does on the C1 version which was the prior year's model, can I assume it is the same?

SOURCE: Relays click. That's about it
try unhooking the wires coming off the power board you should be able to unhook every thing except the switch wire and se plug if the green lights stay on and the red don't come on then you have something loading down your power supply if it still shuts down you need a new power supply

I fixed it myself!
I bit the bullet and ordered a replacement Power Board for AUS$290 and swapped it out myself.
Only took ten minutes, most of that time was removing and replacing the 101 screws holding the back panel on!
Working fine again now.
I did sit the two boards side by side and noticed the new one had moved some of the micro components from the back of the board to the front plus some other small component changes.
If your handy with a screw driver and have some technical knowhow I recommend having a go at fixing it yourself as it wasn't hard and probably saved $200 in service charges (all this assuming you are out of warranty!)

Your LCD has gone bad or their is a high voltage problem that powers the LCD. Usually a inverter board.
