Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.
NB: Please read and understand well, the instructions to enter the service mode, before you begin. Be very careful. Note how to "EXIT" the service mode; after entering and adjusting data. This is very important. Keep in mind; that Videocon uses Toshiba kit to most of its models.

What is the exact model number to your Videocon TV? Videocon uses both Toshiba and Sansui kits. Without knowing the exact kit fitted, it is difficult to inform you the correct service mode option. Anyway, check this and see whether it help you.
