No HD picture

The Protron PLTV-32 only has an analog tuner (NTSC). So you need a digital to analog converter to watch OTA programming. A basic d-t-a converter will give you Standard Definition output (480i) (either on the TVs antenna in or the composite in inputs).

Since the TV can show a high definition signal (720p), you could also use an HD tuner set top box. However, these are significantly more expensive than the $40-70 SD converter boxes that were sold for purchase with the government coupon last year. Alternatively you can use a DVR with a tuner as your set top box (computer with a tuner card) to the VGA or DVI inputs on the TV.

I hope this helps.

By set top box do you mean a digital tuner box? If so and your tv is a newer flat panal than more than likely you wont need it anymore. That tuner will be built in. If this is the case than hook your anntena up to the new tv and go to the menu to do an auto channel search. That should do the trick. If it is an older tv and doesnt have the tuner then hook up the box the way you hooked it up before IE if you used cable than hook it up with cable if you used it with Composite cables(RCA) than use those the reason is some of those boxes you have to set that part up in the settings and that disabled the other output so if you had it set for cable than hooked it up with Composite(rca) nada, nothing would show. Once you hook it up and you see it on the screen then your good to go simple channel search from there. Also if you use cable then your tv needs to be on channel 3 or 4 if you use Composite(rca yellow red and white) then your tv has to be on the input channel that coencides with what input is hooked to.

OK! First, you have NO TUNER in that model. It's called a monitor. You have to use a cable box, satellite receiver or use an older style vcr with a tuner in it. With the vcr you won't see HD stations that broadcast in HD. You will see the old style analog.

The Cox cable box,work before?Talk to Cox cable customer seviced send u another box?Tries unplug the tv and the cable box,replug the tv and the cable box back an hour later.Tv should reset itself back to factory setting.The cable box should update it software.They might work,if they reset themselves.

Tries unplug the tv and the cable box about an hour and replug both.See if the tv reset it self and the cable box reboot it software.Not,than the Tuner board is dead,that the board the coalax signal cable plug into it to get the broscasting signal.

Does the cable box hook-up via HDMI, component (red green blue) or composite (yellow connector)

Unplug,replug the cable box for an hour later.Let the box boot up,and upgrade the softwares.Might have go to ur tv menu to rescan all ur channels again.If this don't work call ur cable company might have to change the box.
