The problem is the HDTV tuner module, replace the voltage regulator U8 with a AMS1117-2.5 IC will fix the problem.

Is there a coaxial input on this tv?

No because it is a monitor only; meaning it does not have a TV tuner of its own.

Is my polaroid TLX-04244B Digital

I checked out the manual for a similar model tv from polaroid...there's only one input for the coax cable from your antenna, so if the antenna's cable is connected to this input, this couldn't be the problem. What I do have trouble with on my own tv is that my indoor antenna location can make huge differences in recognizing all available digital signals. I could even have the antenna facing a different direction, and get different results. There are a few sites you can google for to find your distance from the broadcast towers, too. This might help to determine if you need a stronger antenna. It's a painfully long procedure to try different angles and positions for your antenna each time you run a channel scan, but this might be the only thing that would prevent you from picking up the digitals. I try the highest spot possible, and the one closest to the outdoors. Good luck, I hope you can pick them up soon! (Any antenna works...the industry tries to pass off "digital/hdtv specific antennas" to make a buck. I've used a cheapy rabbit-ears antenna and was able to bring in digital channels, as long as your tv or converter box is converting the signal.)

Can't get DTV programs

You still need a converter box for it to work off the antenna.

Screen shows no signal

HDTV sets are different from the old analog sets.

If your set is showing No Signal or Weak Signal you will have to do the following.
1) Connect an Antenna or Cable to the input on the back.
2) Go into the Channel signal source menu and select either the Air/Antenna or Cable option.
3) Go into the Auto Program Scan menu and SCAN in the channels.

Now you can watch available channels.
