His manner is as follows: look at your TV set, whether there is still some channels that are still visible or not by how moving the channel, continue to do the following:

You go to MENU then to the search mode (TUNING) manual / semi-auto and not the fine tuning.coba your search (search program) and observe whether there is a channel or a broadcast that can be locked?? If not, and broadcast looks continue through without stopping locked , then the damage is on the IF transformer components (6019, 498U, Eo8L, 9074 etc.). But if the broadcast stopped or locked properly, we will most likely damaged or may simply TUNER.

And if there is little change in color or sound, it means tuner were damaged in this case the call occurred shortly pergeseran.Ganti tuner.

Component Tuner not running sendiri.Pastikan supply voltage for the tuner is normal. Good for him VCC (5V/9V/12V) and voltage is 33V for tuning existing and stable, and normal AGCnya voltage of about 50-75% of the supply voltage.

Problems with IF components cause the TV can not lock, the problem at 33V voltage causes a shift in the broadcast or none at all if 33Voltnya not exist.

Problems in the IC program could cause the tuner does not work because the setting is the amount of tuning in IC program.
