If you still have audio it looks like an inverter problem.

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

Monitor comes on, I can see everything perfect then goes black


"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.

Westinghouse LCM22W2 shows a display then turns off after half a second


I have the same problem and have traced it down to a potential power supply issue.  I bought mine at Best Buy in '06 and was told today that they will test the power supply for free.  It may range from $50.00 to $100.00 depending on where you can get it.  This does not include labor for those not qualified to work with electronics.  Hope this helps you.
