This training manual may help.

I was thinking there's supposed to be a red standby light on front, when tv is off and plugged in but none of my working tvs have that, it must be normal.

See page 26 of the user manual.

yes thats the manual I've been reading, it helps a lot, I think I need a good video tutorial on checking mainboard check points, thanks Budm.

Re: sony KDL-46S4100 proper voltage

was looking at the shopjimmy site, they keep advising people that their panel is probably bad, I'm starting to think this panel may be shot.

can't get a menu, flow chart says if 12 and 3.3 are good at g board then go for the a board but says if no menu seen, then it's lvds cable, tcon or panel, tried a couple different tcons, same results.

Re: sony KDL-46S4100 proper voltage

seen so many posts by people trying to fix these KDL models, I don't think I'll even attempt to fix another like it. lol.

sony doesnt show firmware for this KDL-46S4100; but going down the line it does have updates for kdl-46s504 and kdl-46s5100, wonder what do you good folks think of trying one of those?

Re: sony KDL-46S4100 proper voltage

Re: sony KDL-46S4100 proper voltage

I was getting the solid red, green, blue then striped loop on screen, that seems to have went away, I got different a board, with the first one I have to unplug the bl-on connector from a board to g board, then backlights come on, soon as the connector make contact the lights go off, with second a board, I can have the bl-on connected but if everything is hooked up no backlight or anything, if I disconect lvds cable from a board side, backlights come on in 8 seconds BUT if unplug lvds cable from tcon side, no backlighs or anything and whatever I do the sony logo never lights up, not sure if it is suppose to and I never get a menu.

Re: sony KDL-46S4100 proper voltage

not sure, was getting a test pattern loop, now that's gone, just solid color screen but only with lvds cable unplugged from the a board side, when lvds cable unplugged from tcon side, no backlight or anything.

Re: sony KDL-46S4100 proper voltage

quick question, anyone with a proper working sony kdl model, do you have a red standby light, when tv is off and plugged in?, Thanks.

Re: sony KDL-46S4100 proper voltage

I just checked my Sony Kdl-46S4100, When it is pluged in there are no led's lit. only when the power button is pushed does a green led light up. when turned off the green led turns off.
