    I have a protron tv for about one year. the tv has good picture but not sound if I use the HDMI cable. however, with the regular cable it has sound. I called to protron for the warranty but I have to pay to mail it and for return it to me (around $200) and I don't know if they are gonna fix it or mail it back to me saying that there's no problem with the tv. Should I take the risk? or it's better to leave it like that.

    When television is on the picture is perfect. However it starts to make a "humming" sound . Then the words Mono Stereo appear and there is no sound at all. Now there is just no sound but picture quality is good

PLTV-32C has power supply module inside the TV:

Are you getting the 12vdc and the 24vdc from the power supply?
Since your TV uses AC ADAPTER type power supply, you need to check and see if you do have 5vdc (5vdc is converted from the 12vdc power) for the processor.

Need replacement speakers or specs. to find matching replacements for Protron PLTV-32 TV. Attempted to connect two main front speakers from a surround sound set, but no sound until volume at 95% - then... seems to have them in stock.
Go to that web site and put in "PLTV-32 speaker" as the search.
They are going for $24.95 a pair.

Sound/ no picture

Can't really help you with getting sound out of the tv speakers, but you may be able to use the audio outputs from the TV to a receiver as a work-around.

PLTV-32 GOOD PICTURE, Static Sound

If it is under warranty, you would be better off the return it for an exchange as the main board will need to be replaced. this board is not cheap. Good Luck
