I acquired a defective LCD TV which I have already repaired. Problem is the TV only supports PAL and DVB-T and I'm in a country which uses NTSC and ISDB-T. When I tried to scan for analog channels, I was able to get channels but only the video can be displayed and no sound. This may be because the TV supports NTSC inputs through its AV in but not on the RF receiving section. It is able to display the video because it automatically detects it's format. But for sound, the difference in the sound carrier in NTSC and PAL is the reason why I get no sound. The sound carrier for NTSC is at 4.5MHz and 5.5MHz for PAL.
My question is: Can I adjust something on my hardware, probably on the tuner, to make it get the sound at 4.5MHz? or Can I replace the tuner with a compatible one that supports NTSC? or does the firmware need to be modified too?
I hope someone can help me with this. Thank you very much in advance.
