Since you didn't include the model number I will just guess that you have no sound because you don't have it hooked to cable right now. As far as the picture goes, It's likely that either the power supply driving the sustain boards is faulty or one or more of the sustain boards is bad.

Hi,
Check in the menu to see if the audio is on SAP. If it is change it to Stereo. Hope this helps

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

SOURCE: Picture problem with Maxent Plasma MX-42HPM20

Very common problem on these sets caused by bad surface mount caps. Check on ebay for a repair kit it's the only place I know where one exists.

SOURCE: How do you hook up regular coax cable to the TV?

You simply need an "F" connector to "Belling-Lee" converter. about $4.00. At any Radio Shack, Antenna shop. This screw onto the end of the existing antenna connection & makes it so you can plug it into the Socket at back of set.
I have included a link that has a picture.

My sinotex 42inch stl-43vn86d picture flickering jumping top half bottom half no picture got sound

That may be a bad T-CON board, but more likely it's a fault in the LCD panel itself. Check whether it's under warranty before doing anything else.

47" plasma 1080p ... screen went black , sound

Plasma TV's have a shelf life. By that I mean the screen is only good for so many hours depending on the model. Most likely, you have burnt out the screen and the set will need to be replaced. The good news is, plasma TV's used to be better than LCD but that is no longer the case. You can get a very high quality LCD TV for a very low price now. Also they use a fraction of the power and don't generate all of the heat of a plasma.I'm sure this is not what you wanted to hear but the reality is that ALL plasma TV's do this eventually, and it is something that most salesmen back in the day didn't bother to tell customers. If you have an extended warranty, you may be able to get it replaced.

My 42inch plasma bush tv made a load bang noise as i was watching it yesterday. The picture immediately dissapeared, but the sound stayed.

That sounds like the plasma power supply section has stopped working.
Replacement module probably. Fairly expensive, maybe, unless there are some refurbished panels out there.
Hope that helps.

Sounds like main board failure and or power board failure. You need to contact manufacturer and describe problem for tech support. Some of the parts in Samsung TVs have lifetime warranties. Change out of two board is about an hour job and service call is usually comped. Hope this helps. J
