All I can tell yo is that there can be something else, as when the bulb AC power supply is faulty you get same symptoms as a blown bulb. The most common situation is that the bulb has blown and the bulb cannot be tested if not mounting into a working unit.
The lamp power board can be tested by a technician reading voltage out and testing components.

    If the motor runs and there is power, then it is not the main PSU.

    If it is completely off , it is also unlikely a problem on inputs or main board.

    The most common is a blown bulb.

    The only part that cause same conditions is the high voltage circuit that supply power to the lamp, that usually is a separate small board connected to the lamp assembly.

    Normally the user can only replace the lamp, for safety reasons. While a technician will test first the board, reading high voltage out , voltages in to the lamp pwb.

My Sony KDF50E-2000, the projection light went out, i replaced it, it was working, then the replacement light went out too. Is this something with the TV or do I need to buy another light?

There are a few common causes for rapid bulb failure. If you touched the replacement bulb with your bare skin, oils on your skin will cause hot spots on the glass and can cause quick failure. Also, there are cooling fans that provide cooling for the bulb. If these are not working, bulb failure will occur.

I suspect that something has caused a short of one of the diodes in your alternator and the alternator is only putting out 1/3 of the current it should. Maybe even 2 diodes are out. Have the alternator checked.

I have a 98 cavalier and the break lights stay on unless I prop up the brake pedal. what would cause this

ive got the same issue with mine and ive read about 100 people with the same issues or near identical issues ive replaced the directional flasher relay. ign switch,run separate grounds thinking it was a bad ground replaced the light sockets and put new long life bulbs into them. replaced fuses even though they were all good. only thing left is to run a completely new wiring harness and the car simply is not worth the aggrivation. my advice never buy another chevy/government motors product ever again until they can get their act together and build em like they used to in a fashion which enables pretty much anybody to easily repair them with common tools. total morons for engineering a wiring system in such an irresponsible fashion its no wonder all of their buisness is being taken by foreigners.

I have a philips 60pl9220d/37, and when I turn the power on there's a red light i'n the middle of the blue circle and was wondering what it ment and what caused it.

It means your tv is over heating, the bulb. In this case you are most likely to buy a new bulb soon as the bulb is heading into the end of it life.

My sony kds50a2000 failed lastnight. Bulb only?

There could be something else that caused the lamp to fail but if it has 6 to 8 thousand hours on it that is the expected life and it is not uncommon for a lamp to fail this way.
