NVRAM initialization
CAUTION Initializing the NVRAM resets the serial number, the event log, the page counts, and
the EIO card (initializing the NVRAM resets SERVICEmenu values to factory defaults). Use the
service menu to restore the serial number and page counts. Also reconfigure any computers that
print to this device so that the computers can recognize the device. Initialize the NVRAM only
when absolutely necessary. In most situations, use a cold reset rather than a NVRAM initialization
to reset device settings (this will retain the values in the SERVICEmenu).
NOTE Before performing a NVRAM initialization, print a menu map and a configuration page
. Use the information on the configuration page to reset
any customer-set device configuration values that the NVRAM initialization procedure changes.
Take special note of the total page count, maintenance count, and the serial number.
1. Remove any installed accessories.
2. Turn the device off.
3. Turn the device on. When the memory count begins, press and hold the button. Continue
holding down the button until all three device control-panel lights flash once and then remain

4. Press the button.
5. Press the Menubutton. The display should show SKIP DISK LOAD.
6. Press the button until NVRAM INITis highlighted.
7. Press . The device initializes NVRAM and then continues the power-on sequ

TN55X81 Rear Projection color separation - convergence problem

You shouldn't need to do a board replacement, all you should need to do is manually tune the convergence.

You can do this with the built-in user tool, but there's also a far more powerful set of options in the service mode.
