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.

Lost the remote to the tv now it wont turn on manually

the remote has nothing to do with the tv not turning on or off you should be able to push the power button on front of the tv and turn it on that way.if its not staying on then theres something more wrong than just a lost remote

Timer light blinks on and off and tv wont turn on

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.
If ever resetting is no effect then the problem is in the "DM board"
The constant blinking green light means that the TV is not booting up. This is a common problem on this set. Hope it may help you; Regards, VOTIT

Timer light is flashing but tv wont turn on!

When the timer light stoped flashing the remote control would not turn on the TV. The next time the light quit flashing I held the power button in on the TV for about 5 seconds and it came on and has had no problems since then with the remote or the local TV power button.

Power will not stay on

Same TV, same problem. I'll be watching for an answer. The dealer says it is old and outdated and not worth fixing.
