I just bought an LCD 1933A TV. I don't have cable so I connected an indoor antenna to it as instructed ( Radio Shack indoor amplified HDTV antenna 15-254). I turned the TV on and no matter what I did with the antenna, I got a "NO SIGNAL" and then a 30 second automatic turn off. (I live 3 miles from the Empire State Building). What's wrong, or what am I missing or doing wrong?

Hi Dwayne,

The Proton has an NTSC analog tuner and also an ATSC digital tuner. Have you tried switching or changing the SOURCE inputs?
You may also have to use the scan button to have the tuner "find" the channels for you once you determine that you have selected the correct source for the antenna.
See page 9 of the manual.

Get a different antenna or install a roof antenna from radio shack.

The tuner in the RCA has poor sensitivity. Radio Shack sells a inline amplifier that may help, make sure you can return it if it doesn't. Move the antenna outside if possible and as high as possible, that may help. Good Luck!

The input should be selected as 'TV' to get any on-air transmission. Now the input is selected to Cable. Change it to TV. Refer its user manual for more details.

You need to go into on screen TV tuner/channel scanning setup page and change the signal source from CABLE to ANTENNA so it will scan again to pick up off the air signals. Please read the TV user manual for more details.
What is the model number of the TV?

Unless you are very close to the TV transmitter aerial it is very unlikely that you will get adequate signal for digital TV with an indoor antenna. Check with your neighbours to see what they use and where the nearest transmitter is.
Unfortunately, with indoor an antenna, the amplifier also amplifies any electrical interference from other devices in the building.
First step would be to try taking it outdoors (use an extension cord to get well away from any buildings, trees or large metal objects that could block the signal).

The antenna, will more than likely, come with a feed cable with a screw type F connector that you attach to the antenna connector on your Phillips TV. Pretty simple! Most antenna's will come with complete installation instructions.

You don't need a digital antenna; any indoor UHF/VHF antenna will work. The antenna and the TV both connect to the converter box, not to each other.

A standard rabbit ears (UHF/VHF) antenna with flat wire (300 ohm) connections can be hooked up to the coaxial cable that goes to the Antenna (RF in) jack on the converter box by using a balun (Radio Shack catalog # 15-1297, about $8). If you have an antenna with coaxial cable already attached, you don't need the balun.

To connect the TV to the converter box, you need an adapter that has an F jack on one end and a 1/8" plug on the other (Radio Shack catalog # 278-257, about $5). The 1/8" plug on the adapter goes in the external antenna jack on the TV, and the other end connects to the coaxial cable that goes to the TV (RF out) jack on the converter box.

yes you will. either install an outside antenna or get a good amplified indoor antenna. try your old antenna first, but when your picture freezes or it says something like " weak signal " you will need that new antenna

Sony Technician confirmed that that the TV has an analog tuner
2 options - outdoor antenna with digital converter --- or cable service
