Re: Kdl-70w850b Possible Lightning Strike
I installed the Tcon board , along with new cable. I get orange and green flashing lights. I can not get the main board to update . If i disconnect the Tcon board from the main board, power on the tv, power off the Tv, then plug in the Tcon, i get a clear and perfect picture and sound( hooked up computer as test).
When i disconnected the power from the wall , and power the TV back on, goes back to the orange and green flash.
What are my next steps, i feel like i am getting closer..Last edited by Pontgta; 09-18-2022, 04:59 PM.Leave a comment:

Re: Kdl-70w850b Possible Lightning Strike
Yes , seems like i get a couple of different things every time i plug in. Now i getting the 5 blinking lights , unless i “hot” plug in the Tcon. If i unplug the Tv and unplug the TCON , i will get a blue / white light. If i then pug in the TCON while the TV IS POWERED ON, i get the flashing chess , red blue and white( test pattern). I decided to plug in my laptop to hdmi 1 , and i can hear sound , and me choosing inputs, but only the “test” pattern is displayed....Leave a comment:

Re: Kdl-70w850b Possible Lightning Strike
I tried the firmware, but does not load. Only blue flashing light on the led. I need to see about getting a tcon board. I only get the “chess board display when : I power off , disconnect the Tcon from the main board, and “hot plug it in”. If i power on the display with Tcon connected , only 5 red blinking lights, no chess/ checkered board display....Leave a comment:

Re: Kdl-70w850b Possible Lightning Strike
Can you explain this some more.. I am unsure what the "dump and/or programming ability" Does this require a special tool, and or special programing skill? Would it be easier to replace the board? Are we talking about the Main board or the TCON ?...Leave a comment:

Re: Kdl-70w850b Possible Lightning Strike
The Firmware is for the Kdl-70w850b. I received it Via DropBox Because its not available through the regular Sony site. I then used my own USB drive.Leave a comment:

Re: Kdl-70w850b Possible Lightning Strike
Thanks for all the replies, unfortunately i had to leave after the storm due to work. I am working out of town all week , so i will post pictures on Friday afternoon or Saturday morning of the board layout. .
The storm took out my cable modem, and Direct Tv receivers as well. I disconnected them, hoping the screen would come back , but no luck, definitely problem with the TV.Leave a comment:
