Panasonic TC-60PS34 no signs of life (no power, no standby, no clicks)

[Nathan Explosion]

So, to make a long story very slightly shorter, I have a TC-60PS34 which stopped working last November. I assume it was a power surge. No standby light, no response to any power button, no clicks when you plug it in, nothing at all. Squaretrade replaced it after it took a month to get a repair tech out to see it, and I was planning on disposing of it or selling it for parts. Well, it kept staring at me, and last week, I figured I'd make some calls and try to get it fixed. After talking to the same technician who finally came out for Squaretrade, he advised me that in 90% of cases it was the power board, and otherwise it would be the main board. He sent me to ebay, where I picked up all three of the power boards for $90. I replaced them, and the TV still shows no signs of life whatsoever. Still no lights at any point in time, no clicks, nothing.

So my question to you guys is whether I move to the "main board" as he described it, which I have concluded is TNPH0914 suffix AE, or if there is anything to test otherwise.

I have a digital multimeter and a vast array of tools, and would like to claim I am fairly competent, but maybe not the best solderer around.

Cliffs notes:
Panasonic TC-60PS34
-probable power surge
-no standby led, no power, no relay clicks when plugged in
-main and two sub power boards replaced with no apparent effect

Thanks!

Can you take a picture of the chassis arrangement of all the circuit boards? So we know what we are dealing with.

Sorry it took so long. Here is a general shot of the chassis from the back. Do you need closer shots of anything?

there's usually a fuse near where the power comes into the board have you looked for one or can you get closer pictures of the power board

i found them check these fuses

All of the obvious ceramic fuses test ok, even on the old board(s). Though I may need a better multimeter to be sure.

the 2 i pointed at arent ceramic, if you arent getting any power at all have you connected it to power and check for voltage on the board, starting by those white fuses i pointed out

Sorry it took so long to update. This is a picture of those fuses. Are they not ceramic? My DMM shows all fuses on all boards as having 0 resistance. My DMM is not auto switching for currents, where on the board should I see AC vs. DC?

Thanks!
