Question about Sony KP-46WT500 46" Rear Projection HDTV-Ready Television
This looks like a problem with the Hv Voltage section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, or have this done by a qualified TV technician.
Or check the voltage test points on the HV / Horizontal board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.
I would suggest that if you do not have a background in electronics that you have a qualified electronics technician who knows TV take a look at your set and perform these test.
I hope this helps,
