Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable

SOURCE: Samsung LCD TV, no picture only sound

My Samsung LNT4669F has two problems..the first is that it takes about 3 minutes to turn on. The red light at TV bases flickers on and off but the sound is there back and forth..Finally, the wite light at base turns on and the TV makes a noise as if it just got turned on and it stays on..why does it take so long?

Secondly, sometimes, the HD channels flicker so badly that I cannot even watch TV..so badly that sometimes the picture is blank..however, the regular channels are fine..Can you help?

It sounds like a loose contact to your T-con panel. Before the problem happened, had you recently moved your TV? A picture would help my friend also if you have the model number.
