SOURCE: I have a 22 inch

hi,
Its sounds like the LCD pannel driver ic faulty. In lcd tvs bellow 32 inches this ic is integrated to (part of) the lcd pannel. In 32 inches or above this is a separate circuit board name T-Con board. In your one it is on the pannel itself. There is no repair possible with this. This ics drives the pixels on the LCD screen. To repair the same You have to replace the lcd pannel. The LCD pannel is the most costly part in an LCD tv. Also it will be available only from the authorised servicing center for the Hisense. Its Better to go for a new tv than reparing it.
OK

SOURCE: New Hisense 55 inch LED TV does not have volume

Check its speaker. If it found OK, check and replace the audio output circuit board.

SOURCE: My hisense 50 inch lcd tv has picture but no sound.

If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel

SOURCE: My Hisense 50 inch smart screen has picture and sound but both keep going in and out every few minutes....i just bought this TV from walmart not even a week ago

Go back to Walmart this must be a warranty issue.
