Question about Toshiba 43A10 43" Rear Projection Television
This might be an indication that your voltage tripler have gone bad. You will have to use a HV probe to measure the voltage on the anodes of your Red Green and Blue CRTs to see if there is HV present. Then you will have to measure the voltage off of the IHVT (Integrated High Voltage Transformer) to see if it is delivering the proper voltage to the voltage tripler. If there is not HV at the IHVT then you will have to check the HV and Horizontal Circuits for a problem.
If you do not have the equipment for these checks I would advise that you take the TV to a qualified TV repair shop or have a technician come to you place to check the TV.
I hope this helps,
