It sounds like it may be a problem with the whole optical engine, which is like an 800$ part if you can find it. I would consider selling the tv for parts and replacing it, as it's not gonna be worth it as you never know when the next problem will occur and a new tv will have all new parts. And as I always recommend, research models of tv's thoroughly online for user reviews to know about possible future problems certain units have.
Thank you,
Lee

How to reset the lamp timer on Sony Projection TVs.


If you have replaced the lamp in your Sony projection TV you must reset the lamp timer to get rid of the message saying that your lamp needs to be replaced. Let's face it, you know you already accomplished replacing the lamp but the TV isn't smart enough to know that. I will explain in detail how to accomplish the reset procedure.

Resetting the lamp timer is a complicated procedure but you should be able to do it if you have plenty of patience and know how to follow instructions. Read the procedure over first several times before trying to do it and locate all the buttons on the remote. You may want to try the procedure on the remote to make sure that you have the sequence memorized.

By the way the lamp life is figured to be from 5000 to 8000 hours. That is not much time if the TV is being used for more than 8 hours per day. If you do the math and watch your TV for 8 hours per day (not uncommon) the lamp will need replaced in 3 to 5 years. So be ready to do this procedure again in the very near future.

Here is the procedure.

All commands should be done using the factory remote:

1) enter the service mode by pressing display, 5, volume +, Power on
2) press JUMP 3 times
3) to display the time press channel 2, 9 times
4) to reset lamp timer press channel 3, MUTE, Enter
5) to check the time press channel 1, 7 times
6) when complete turn set off to exit.

How to reset the lamp timer for Panasonic DLP TVs.


When you replace the lamp on a Panasonic DLP or LCD TV you will need to reset the lamp timer to zero for the TV to reset the lamp timer and extinguish the change lamp indicator.

There are two methods used depending on which model TV you have. The older units use the first method and newer units use the second method. You can tell which method you need to use by whether you have a PIP and/or SPLIT button on your remote. If you have them use the first method, if you don't use the second method.

Method number 1 (for older units):

Follow the procedure below. You use either PIP or SPLIT button depending on whether your remote has SPLIT or not. Some do not.

Perform lamp timer reset only when the lamp has been replaced. The idea is to know when to replace the lamp before the end of it's life when it could explode or short out causing a hazadous condition. If you reset the lamp circuit at any other time the replace lamp warning will not come on at the recommended interval.

Be sure the power cord is plugged into a properly grounded wall outlet.
Then, press the POWER button on the projection display or the remote control to turn the unit on.

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

If your remote does not have a split button you use PIP, if it has a split button, you would use SPLIT.

When reset procedure is complete, the screen on the TV will indicate that the lamp has been reset. When lamp time reset is finished, the LAMP indicator goes out.

Method number 2 (for newer units):

Press volume down on the TV and the zero button on the remote at the same time for longer than 5 seconds and it will reset the lamp to zero.

These procedures should reset your lamp timer and you will be good until the current lamp fails or the change lamp indicator illuminates again signalling that it is time to replace the lamp. Three to six years on average depending on how much you run the unit per day. Do not ignore the indicator. Change the lamp immediately to avoid further damage and expense or worse.

1. Plug in the AC Cord, and turn on the power by pressing the POWER button.

2. Press and hold the VOLUME DOWN button on the unit and the SPLIT key on the remote together for over 5 seconds in power on condition.

When the reset is finished, the display appears and the LAMP LED goes out

Hello.. meseta809


first off all it's not necessary to have the TV on to reset it. the problem is the dmd need to send the info that you have a working lamp.

try this to see if it work's

Panasonic TY-LA1000 TV Lamp Reset Procedure/instructions:
Ok, so apparently there are a couple of different ways forum members have found out how to reset their Panasonic Lamp timer (this should apply to all of them, not just the TY-LA1000 specific lamp)

“Hold the VOL down button on the TV and the SPLIT button on the REMOTE for five seconds”

Again, you will need to press the Volume button on the TV while pressing hte SPLIT button on the Remote Control for five seconds, it will NOT work if you try to do it both from your remote!

Panasonic PT50LC14 Power issue


We have a PT-50LC14. We replaced the lamp 6 months ago with a TY-LA1000 bulb we bought from a company online (not directly from Panasonic) and it worked for 6 months. Then the TV started turning off on it's own...sometimes it would not come back on for an hour or so. We called the lamp company and we luckily had 1 day left on our 6 month warranty!! They sent us a replacement bulb and the TV would never power on. It would try to power up, but the bulb would never ignite. The power light would flash and then the lamp light would flash every 5 seconds. I had a friend that has the same type of TV and she ordered her bulb directly from Panasonic. I borrowed her lamp and it powered right up. We then called the online company and they sent us yet another replacement bulb, and I tried it today and it works. It seems like these TVs are very particular about the type of bulb used. Next time, we will be ordering ours directly from Panasonic and just paying the extra $100. We have been without our big screen for 2 very long months! I had called a local tv repair shop, called Panasonic directly, and read through countless internet forums, and I thought we were going to have to replace the ballast or get a ballast repair kit and start messing with the circuit board.

Reset hour meter for replaced lamp


push and hold the PIP (same as play) button in the remote control
push and hold the menu button on the front panel of the tv.
Do both actions simultaneously. Of course you have to be close to the tv to do this: pointing with the remote at the sensor AND holding the menu button of the tv panel.
Do this for some seconds and the screen is going to tell you the timer was reset sucesfull and ask you to push exit in the remote control to finish
