We live in Jimabaran not far from Sidewalk Mall. Can anyone recommend a TV technician in this area. We have a Sony smart TV. When I tum on TV we an have excellent picture and sound. We have an MNC subscription package with a number of channels including ABC TV Asia. Recently found that changing MNC channels the sound would disappear. Sometime turning it off and on the sound might come back but now no sound at all for the MNC channels. Good picture but no sound and meanwhile if I just go back to the TV itself with Youtube for example, no sound problems.
