Need a new lamp

Read how to reset the timer and have made notes but I also need to replace the lamp according to the tv screen. Where can I purchase the lamp at a reasonable price or is it better to just get rid of tv? Thanks,

    Information was helpful but I will need to find a new lamp as it is definitely bad.

  • tomylake Dec 11, 2008

    What numbers do I need to type in to make sure that I get the right lamp? Do I need nust the lamp number or model of tv?

  • tomylake Dec 11, 2008

    Thank you so much because I thought I should google the PT40LC12 number to order the replacement bulb but with your info, I realized that I need bulb TY-LA1500. When I removed the cover, replace with this bulb. I will try to google and if not successful, I will write and ask for your help again. Thanks again, Jen

    There are such varying prices on these replacement lamps, does that mean that some lamps are better than others. I would rather pay a little more and get a good lamp rather than pay less and get one that will blow in a year. Thanks, Jen

    How will I know if it is just a bulb or the complete set? Is it hard to remove the bulb from the casing and replacing it with a new one? How will it be listed so I will know if I am getting a bulb or the complete set when I google?

If the la,p still works, just reset the timer and wait for the lamp to go bad, Which it will do eventually, but lets not fix it if it ain't broke. In the mean time you can find that lamp online anywhere and by the time you have to buy one it may be a little cheaper. If this helps please take a few minutes to rate the response. Thanks

    You can do one of two things, first, give me the model number and I can provide a part number for you or you can just google you model number with lamp and you will get several response with the part number. Either way will get you taken care of

    The big difference in the lamps will be whether they have the enclosure or not. If you buy a bare bulb (it will be cheaper , about $130) you will get just a buld and have to remove the old one from the casing and install the new one. For more money, you will get the buld and the casing as a complete package. I usually get a bare bulb and install it in the case myself

    When you google the lamp, you will see the words "bare bulb". That is the bulb by itself. You can use a srewdriver (philips head I believe) to remove the old bulb and reinstall the new one. Just remember where the screwa go and DO NOT touch the bulb with your bare hands. Use a pair of gloves. The oil from your skin could cause the bulb to go bad. I know it's hard to believe but it's true.

Procedure to reset Panasonic TVs

If you have replaced the lamp in your Panasonic DLP TV and are having problems such as a message on the screen telling you to reset the lamp timer or the unit not powering up, you probably need to reset the lamp counter. All DLP and LCD TVs which have high intensity lamps generally need to have a lamp timer circuit reset after a lamp change. The manufacturers want to give you a heads up prior to having a catastrophic event such as a lamp exploding which could cause a fire as well as other damage.

Therefore in many cases until you reset the lamp timer the unit will not operate or it will keep reminding you to reset the lamp timer which is very obnoxious. This is not a hard procedure but you will need the original factory remote to accomplish the task. Generally the procedure involves pushing a sequence of buttons.

I recommend placing a piece of masking tape on the rear of the TV with the date the lamp was changed to make it easy to remember when the next lamp change will be necessary. Also you could purchase a lamp now to avoid paying more in the future.

The following procedure should solve your problem:

1. Turn on the television.
2. Press the down button on the TV display (not the remote)
3. While pressing the volume button, press the "split" or "PIP" button on the remote.

This should reset your lamp timer.
