Pnasonic PT-EW540 Lamp reset

[wwbielsko]

Hi,
My lamp has going to end its life by counter, but lamp phisically seems to be in good condition.
As far as I get known there is atmel 24c64 eeprom used to save lamp life counter. Here is dump of it but unfortunately there is no counter in plain text.
Maybe someone has clear dump of it or has tips how to set counter value.

best regards

Try to do so.
1.Turn on the projector and press the Menu button on either the projector remote control or the projector itself.
2. Select "Option" from the menu and navigate to "Lamp Hours" in this subcategory. This screen displays the number of hours the projector lamp has been used.
3. Press and hold the "Enter" button for three seconds to display the "Reset Lamp Hours" confirmation screen.
4. Select "OK" on the confirmation screen, then turn off the projector to reset the lamp hour counter.
5. Return to the Lamp Hours settings screen to verify that the lamp timer has been reset to zero.

Or try to pull out the lamp and put it back in, it should reset.

Thank you for support, but unfortunately in this model we cannot reset lamp life cycle manually. It is written in eeprom attached to lamp basket.
So, there is need to change flash and program it again or flash it with clean dump.
Its not about replacing lamp but giving extra hours to current one.
So we need:
- dump from new or working lamp of 24c64 chipset
- flash it again and put it into current lamp basket to be read by projector
