Re: Kdl-70w850b Possible Lightning Strike

Something not clear here, the first post tells that chekered image with no b.light, now b.l. is present and also checkered image when tcon hot plug, this is very strange so my diagnosis confirmed, bad tcon surely (tcon memory), and maybe a faulty b.l.

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.

Sony has a T-con and a panel attached to the motherboard, that is, when it is turned on (self-diagnostics occurs), the processor verifies (as if serial numbers) and if it detects someone else's T-con or panel, it will give an error, in this case only an update helps or EEPROM transplant.
Error code "5" is a problem with T-CON.

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..

Re: Kdl-70w850b Possible Lightning Strike

Hello,

Was 1 orange/amber. , 1 green , but since last post finally got it to update. I cannnot thank everyone enough! The fix was to make sure the file on the usb drive was correctly unzipped.

These are the instructions.

File information:
Download file: sony_tvupdate_2014_3004_aaa_auth.zip
Folder on USB: sony_dtv0FA40A06A0A6_00003301
File in folder: 00003301_041e0000.bin

Note: For Main Board Replacements, must do below:
1.Install the software
a.Insert the USB device with the latest software.
b.Connect TV to AC power.
c.Wait at least 20 seconds.
d.Press POWER on the TV to turn ON the TV. ( even though the green and amber lights were flashing). I left the TV alone , ate dinner , and when i came back i had a “update complete message”.
e.Wait until the Software update is completed

The TV is Alive! Thank you again everyone.

We're not in fugging junior high school. The bickering will stop; one way or another. This forum has an 'ignore member' function; those whom can not get along, I suggest use it!
