Good Morning,

The best way to troubleshoot your problem to make sure it's just a monitor problem is to borrow another monitor from a friend for just long enough to connect it to make sure your computer is displaying through its graphics correctly. If you find that it is, then you will know that your monitor has failed in any number of ways (most likely the backlight hardware) and that the best alternative for you will be to replace the monitor.

If your computer will not display on the borrowed monitor, then you'll know that your video card in your computer has failed or that it has other motherboard issues.

Best Regards,

Marcus

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 flashes logo and then turns black.with red lights on


Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Unplug if you have not done so BOTH units from power for several minutes (any cable or satellite box also connected.

wait several minutes and restore power to all units which may allow them to reboot.

If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

I turn on the unit the green light on the monitor lights for 2 seconds then blinks red 4 or 5 times, pause, blinks red 4 or 5 times, pause,?. Monitor remains black.


This sounds like a time out mode for no signal. there is a factory reset to factory sets. there is a way to do this in your manual. usually it requires a signal into the Antenna input.

Monitor Black, Green Power Light Flashes Monitor is 4 yrs. old


Assuming you've already checked your driver and system settings, tried a different monitor, and checked the cable and connector pins, this would almost certainly be a problem with the power or signal circuit board inside the monitor.
