Our Toshiba 43A10 projection TV stopped displaying the picture. We have audio though. I thought it was the lamp/bulb, but when we took it apart to look at it, the three projectors inside will still flash a burst of light when powering on the TV. Any idea what is wrong with it and how I can fix it?

The red CRT is most likely not the culprit. If water got on to any of the boards such as the red CRT driver board it could damage it wich also at the same time can load down voltages (200 volts etc) that can have a global affect on the other CRT's. Changing any on the CRT's by the average consumer is NOT recommended because you are dealing with a device that requires 30 KV (thats thirty thousand) volts to make it light up. Take these as warnings and consult with a technician.
