Lo que preguntas es algo muy ámplio...
¿Qué necesitas exactamente?
He visto por la red que para entrar es el siguiente procedimiento, a parte de algunas funciones que puede que te sirvan (todo bajo tu propia responsabilidad, es algo "delicado" moverse por estos menus así que cuidado)
1. To access the service menu, with the TV off, press the following buttons on the remote control sequentially in rapid succession (note: if the TV is already on, you can start by turning the power off, but then you should enter the full 4-button sequence within about 3 seconds to avoid a lamp restart):
<DISPLAY> <5> <Volume +> <POWER>
2. Press <JUMP> until the PANEL service menu displays.
3. Press <2> until the OPTION_E category appears.
4. The “LampTM” (lamp power-on time in hours) and “LampCT” (lamp on/off cycles) entries are in the first item in the OPTION_E category. If they are not displayed, press <1> repeatedly until they do.
The display should look as follows:
PANEL NVM OK 9 OPTION_E
0 LAMP 0 Diff 1
LampTM #### LampCT ####
To reset these counters, press <3> <MUTING> <ENTER>.
“WRI-EXE” should be displayed momentarily in red text, followed by resetting to “0”.
5. To display the PanelTM (total LCD panel power-on time) entry, press <1> until it displays.
The display should look as follows:
PANEL NVM OK 9 OPTION_E
7 SH SFT1 10 Diff 1
PanelTM ####
6. When done, exit the service menu by turning off the TV (note: you can turn the TV back on immediately, but you should do so within about 3 seconds to avoid a lamp restart.
