The TV just went dead, I pulled the back off and checked the fuse it's OK. Went and unpluged and repluged all connectors hoping for a loose connection but still nothing.Performed a visual check on transitors ect, no burnouts Possible power supply / board?
The power supply may have failed components. It is also possible that there is a failure in the scan amplifiers and in the high voltage sections that caused the power supply to fail. There are a number of scenarios that can cause this type of failure.
The set will require proper troubleshooting to service it. These types of failures will usually not show anything visually.

The fuse is inside the chassis and likely soldered. Unplug the TV, press and hold the power button for 30 seconds, repeat. Plug it back in and see if that has reset it. Is the outlet good, or did the power outage trip the breaker?
Check the FBT for high voltages?Resolders the FBT?Unplug,replug the tv an hour later,let the tv reset itself back to factory mode.Tries these steps,tv might function again.
No power is coming to TVPlease check the power cord, the plug and the socket. See if it is OK by connecting to any other device. If this is OK then the safety fuse inside the TV is blown. You have to get it replaced.
Barry, remove the back cover by removing the screws with an arrow next to them. The fuse is located on the left side as viewed from the back, where the power cord connects to the circuit board.
Most of the time the Horizontal circuit fails and by design the Power Supply will also fail.
The smell was one or more components burning
or over heating.
There is a good chance it will be a costly repair.
Hope this helps,

not only one component might have been damaged! check for capacitors for bulging on their upper part! also check for open fusible resistors and power transistors for shorts
We just experienced the same thing. My daughter was watching TV and it went dead. We could not get it to turn back on. I'm guessing that this model Sony TV had a 13 year life expectancy. I offered it to a local technician who refurbs and sells TVs, and he wasn't interested. He said he doesn't mess with anything over 10 years old because it's too hard to sell. We just went ahead and bought a new LCD HDTV. It's a shame though. If someone were able to fix the old TV, I'm sure a nursing home or non-profit facility could use it. Our only other option is to pay $15 to have it recycled.
video card went out in the tv. You are saying you need a schematic. Be real careful getting into tvs. They have very large capacitating capacitators in them that can electrocute you. You need to take it to a repair specialist and have them run a check on it. Sounds like the video card to me though.
Thank you very much
