I wish there was an easy scientific method to see my bulb's current life/brightness.
on avs, they have the procedure for accessing the TV's service menu so you can see your bulb life..it will also tell you how many times you have turned the TV on/off(called start or power cycles or something) which also affects the bulb life...
here are the instructions to view your bulb life:
With TV turned on:
1. Press "mute" on the remote - 1/2 mute appears on the screen
2. Press "mute" on the remote again - mute appears on the screen
3. Press "mute" on the remote and hold the mute button -
4. Press the "Menu" button on the TV's front panel. "S" will appear in the upper right corner of the screen.
5. Press the "Menu" button a second time and the "S" will disappear. On the left side of the screen you will see "RCUT" followed by two numbers.
You are now in the service mode (this is where you can scroll through the options using the up and down channel keys shown above).
6. Press "9" on the remote and you will access the diagnostics page. In the right hand corner is the lamp time in hours.
7. Press "power" button on remote to exit the menu and power off the TV.
CAUTION: Do not use the up and down volume keys on the remote in this menu as it can alter the data and can be dangerous.
