| Philips | 29PT9416 MG7.1 | Service Mode entering | Use the standard remote control and key in a special sequence '0,6,2,5,9,6' followed by pressing the 'MENU' button. If the main menu also appears with the service menu just press 'MENU' again to clear it.. The other way is to short the two service pins on the signal panel (pins 2 and 3 of connector 0356). The advantage of this last method is that all the software protections are turned off. | 14-09-04 |
