Resetting the lamp timer for my Panasonic

You need the original remote to reset the lamp. Try to find a neighbor with a similar tv or buy one off ebay.

No picture and the power light blinks

A red blinking light could mean that the lamp timer is at it's limit and it is time to change the lamp. You will also have to reset the lamp timer by pushing and holding down 2-3 buttons on the tv or remote. Refer to your user guide for the proper way to reset and or change your lamp.

Lamp light blinks 3 times shuts down

The CLS problem. Im thinking that at least you made a visual inspection of the power suply and the capacitors around it. Then if everything normal in the area then the microdisplay (inside the ligth engine) can be damaged. (when the tv is working normally the microdisplay sends a pulse to turn on ballast and lamp finally.

The sweetkyman: when the fan is bad th tv shuts down imm. (if you unplug the fan when the tv is working normal the computer detects the overcurrent system works and shuts down the set) when a fan is all dirty and tons of dust on it the tv tends to work but after some hours the tv shuts down.

Replacing lamp in rear projection tv

To do this, press the ENTER button on the TV and the MUTE button on the remote at the same time. After 5 seconds the screen should come up and it will read "Lamp use time...Total lamp use time ....lamp reset" Press the center button on your remote (the circle button right in the middle of the four directional buttons) and you will be reset to -0- again. Your orange light should now be off.

Lamp meter on Panasonic PT-40LC12 ?

I just had my picture go out two weeks ago. I took it to a local tv repair shop. They replaced the thermal fuse. I also had a spare lamp so they also replaced that. I'm not sure if they reset the lamp meter but this is what I found surfing around...try at your own risk. I'm going to try this when I go home tonight.

Good Luck...

Press the power button to turn the unit on.
While pressing the Vol-(volume down) button on the projection display,
hold down the PIP button on the remote control at the same time for more
than 5 seconds. When the reset procedure is complete the following message
will appear on the screen. "Lamp time was reset to 0".

Hewitt Packard high definition DLP tv Product #EX543AA#ABA need part, hp no longer carries them.

I have a brand new L2114a lamp for sale. I paid 299 plus shipping on ebay but it turned out to be the wrong one (despite what the manual says). I ordered the correct one I needed from HP. I am willing to part with it for 200. I can send pictures of the lamp and the box and the reciept. This is a BRAND NEW LAMP.

This lamp works in the following televisions and replaces the lamps listed below:
HP Pavilion md5020n 50-inch High Definition DLP TV L1735A
HP Pavilion md5820n 58-inch High Definition DLP TV L1736A
HP Pavilion md6580n 65-inch High Definition DLP TV L1737A
HP Pavilion md5880n 58-inch High Definition DLP TV L1798A

Lamp keeps burning out. I have had the tv 2 years. The original lamp burned out in 1 year. I have since replaced the lamp at least 3 more times in the following year. Help!


Im not at all familiar with your sony model but I do know that when A lamp is replaced you must reset the lamp timer if it is not reset it will cause premature lamp failure.
This is normally in the engineers menu as I said I dont know your model its not one I recognise so im sorry but I cant tell you how to enter service mode.
Hopefully one of the techs on here will know how and help you.
