My chanals on my tv won't work

try moving the antenna around as it is the most common problem where i reside and most of the time when people buy a new TV with an antenna, they have to set it up where it can catch proper network.............or if that doesn't work then i prefer that you take your TV to a technician to check out the fuses.

Hi i do a lot of projector tvs. there are a few things it could be i will give cost prices to.

1 it could be high voltage problem flyback cost is 395.00
2 you have audio so tuner is working ok and cable feed ok
3 it could be power supply or horz problem that part to servicer is only 25.00 they charge 200.00
4 it could be your high voltage spliter common with this problem cost plus parts 195. to 295 the high voltage splitter only costs the servicer 45.00 dollars and they are easy to put in sometimes
but you do need a qualified person to do it . There is high voltage
and you have t be careful

to sum it up .you are not getting high voltage to turn tubes on or a weak signal . my guess with out looking at it is hv splitter

I hope this helped doctor video leadingedgeelectronics since 1987

Buzzing noise

It could be a high voltage transformer. The serial number won't help me locate the part, but there should be a part number on it. Anyways, this could be the transformer on it's way out. When they are on their way out, sometimes they will amplify the noise through the system and buzz through the speakers too. If you find a part number, check it out on to see what a replacement would cost.
