Re: Sony xbr65x900c sound yes, no backlight or image.
been trying to check thru those tiny test points that look like holes in the board, 2 of them close to the ic measure 3.4v but i cant tell which one is for 18.
getting no bl-on voltage at both connectors on the big powerboard or the bl-on of 6602, thats with the cables hooked up.
did you tried before to play with firmware update ???
EDIT cn6602 BL_on taken from power boards socket... any time no BL on on it will be the cn6602 same... this why we disconnect the cable on this socket and asked you to messure the cable only and it was 0 so this boards wasnt issue to kill BL_ON... the main boards didnt send it to power supply... and IC9017 pin 18 are the BL_ON
but on this same IC pin 17 Panel power on are high >3.v mean the screnn if its in place it will have picture Tourch methode.. in case the T-CON didnt send error to let IC9017 bring pin 18 down.. as your screen out... its so hard to tell as we need to know what we are talking true or not since no screen in place
yes, messed around with it quite a bit, then you said stop that.
there are way we can do with out screen
you need to pull the BL_on cable from the powerboards socket which it come from MB
and on the socket self feed BL_ON with power_on let see the error BL remain high and no PIN 18 high or no BL lit on. with this test you should hear music

ok, took 3 out jumped pin 3 with 9 put connector back on, got orange/green blinking for about 30 seconds then went solid red for a few seconds then went solid yellow for a few then back to solid red, turned on with remote, no backlights. Guess i can put the long piece with all the boards back in place and hook up the screen, none of the screws attaching the long piece to the rest are ground screws are they? or can try something else.
