Question about Televison & Video
Three bulbs, no. They are not bulbs in the sense that you are thinking. The way that it works is there are three small high intensity CRT guns. There are three because most images on any TV can be created with three basic colors. They are Red Green and Blue (RGB). This has been the industry standard since the first projector came out and since color tv came about. Each Gun is pointed at a specific angle towards the Rear of the TV and is reflected off of a mirror then is focused to its appropriate spot upon the viewing projection screen. Gotta love math.

The main reasons of your problem is the bulb which is already faulty to its end. The unit will automatically shuts off when it sense a bulb failure. But before you replace the bulb I would advice you to work first on itspower supply. Look for open fuse/fusible resistor and spot some bad solder joints. This will do the same symptoms like what it showing now. If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.
Hope I helped you.
Have a nice day!
