Re: Sony KD-70X690E Bravia; Bad TCON? Bad panel?

With your help, I made progress this weekend. Thank you! With ribbon-cable "pin" 6 blocked with Scotch tape, the TV now shows the Sony logo and a picture. Cool!

However, although the picture and text are sharp, the left half of the screen is orange and dark. (See photos.)

Does this mean the TCON board is OK and something is broken downstream of the TCON?

Why is the screen orange after Scotch-taping? In the Scotch-tape-repair videos I watched, the screens don't become discolored...

What's wrong with my TV: the TCON, the panel, or something else? I'm stuck.

[B]Problem:[/B]

Last week, my Sony KD-70X690E 70" stopped displaying a picture. The TV powers on, and the back lights power on. However, the TV doesn't seem to boot up. I say this because the SONY splash-screen logo does not display, nor does any picture display, nor can I invoke a menu by pressing "Menu" on the remote. Other than back-light bleed, the screen is black.

[B]My troubleshooting got me this far:[/B]

With the left-hand TCON to bottom-board...
