Circuit Diagram for Sony TV Model # KV-35S40 Wanted
My Sony TV stopped working (no picture or sound). The standby light does come on, but nothing else will. I checked the "Heater" check light on the back of the big tube and it is not coming on. Not sure if it's a heater issues, power supply or something else. I may be able to figure this out with the circuit diagram. I'll pass along what I find out.

2 days ago the same thing happened to my tv which is the same model you have. please reply if you find anything out.
I did get a hold of the circuit diagram, but it didn't do much help because I can't understand it. I thought there would have been some trouble shooting procedures with it. In any case, check the "heater" on your TV. To do this you need to take off the back cover. Not too hard, just a dozen screws. On the back end of the "big tube" there is a check light for the heater tube. (The light is in a little eye shaped drawing on the circuit board). If that is glowing (TV has to be in the "on" position with the little red light flashing in the front), then you have a different situation than me. My heater light is not glowing. I called a TV repair place and they said it looks like there isn't any charge going to the heater, but not that the "big" tube is shot. They really couldn't tell me anything else without seeing the TV, but did say it would cost about $150 to $200 to fix. I haven't pursued fixing the TV yet, but will most likely.
I have the same problem on my TV. It is in repair at present and the boss thinks the part behind the big tube, a funnel shaped thing the size of a small football but hollow with a lot of thin copper wire around three or four sides is defect and needs to be replaced. But he can't easily get the part. So he pleads for patience; it has been a month so far. Any suggstions where I might get the part in London UK? Or is it not worth hanging on?
