My mitsubishi wd-62526 will turn on with sound but no picture. can't even get into the menu. stays on for a minute shuts off and the lamp indicator light comes on.
Having in mind that a generic lamp will give you 4500 to 6500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours and that you TV is 4 years old more likely you are looking to replace you lamp;The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
You can check DM;
If you can hear your TV fan working is NOT you power supply,but if you hear a constant clicking you ballast needs to be replace,
A ballast is an electrical component used with a fluorescent bulb (or mercury vapor lamp or arc lamp) to conduct electricity at each end of the tube. It supplies the initial electricity to the bulb that creates light, and then it regulates the amount of electricity flowing through the bulb so that it emits the right amount of light.
