Where's your 18 to 26 V, 8v 6.5v. Your secondary powers are not coming up on your T con. When you took the metal shield off and heard the power supply click what you did is you shorted 12 V to ground. You probably touch the metal shield against the fuse. Now I would advise going through your main board and checking every single little pico fuse that Sony puts on those boards.

Sony is fuse crazy with their boards it's ridiculous

inductor coils all have voltage, 12.3v 3.3v and 1.3v
Fuse resistance is 0.5 ohm
Not the slightest effect from wiggling LVDS cables, or tabs, or any cables at all. The only thing that made anything happen was when I took the sheild off the T-con and checked voltage. There was a clicking that came from the Power board, and the white screen flickering along with the clicking. After that just white screen. After I swapped T-con boards, its back to black with backlights on.

Check voltage around the inductor coils on the tcon.. Is there anything besides 12v?

Keep in mind.. This is a Sharp LCD panel.

Look at me. I bought 5 for the xbr75x850c and still no picture until forced.

What happens when you wiggle the LVDS connector cable while thbe tv is on?

I have 2 T-cons though, and both were working before. Highly unlikely both would fail while being stored in a box, no?

Sounds a lot like the T-con took a shit... SMH

So I'm at my wits end with this TV. I had 2 of these sets bought at the same time. Both went dark with Backlight 6 blink error. Ordered strips, installed strips, worked for 2 weeks, then same error.
Ordered power board since it has brown area by backlight connector, and has to be the cause of the issue. Instal board, backlights (edgelit) works again, but now no picture. Sound and backlights, but no picture. I can tell by the edgelights its booting up.
So I start checking the cables and such on the Tcon, and after checking the fuse, the screen starts up and goes all white. At first there were horizontal lines, but they fade and the whole screen goes white.
That tells me that its possible the panel isn't toast, which is what I figured. If it will go white, its getting signal of some fashion I think, yet after 2 days I can't figure out whats going on.
One of the TV's panel cracked, so I have 2 of everything to swap out, which quickly eliminates things, to an extent. I've swapped out everything more than once. 2 T-cons, 2 main boards, harnesses, etc.
I'm a whisper away from just tossing it all and eating the $200 loss for parts bought. I took a voltage reading off the tcon at the fuse, which has written 32v, 2.something Mamps, yet I get 12v, both sides.
I would be extremely thankful for any suggestions or advice. I figured a driver tab or ribbon on the panel got damaged and that was the issue. Yet when I got a white screen I figured theres hope its not the panel. Yet its the only thing I can't swap out. ugh.
