Check and replace its tuner. Before replacing the tuner, check it for other inputs, like DVD player and if any other, and make sure that the video section circuit to your TV is fine. Contact any service technician. Electro help

Sharp TV model LC-20AV1U - I need to reset it so I can get it to recognize my over air antenna after cutting cable TV


Hi Loretta,
The reason you aren't getting any channels to work on this TV is because it has an analog tuner. Now a days most channels are being broadcast in digital format and the TV needs to have a digital tuner.
In order to get the antenna to work on this TV, you will need to have an OTA converter that will receive the digital channels and send the signal in analog format to your LC_20AV1U.
Let me know if you require further assistance..

I have a RCA D52W20 rear projection HDTV. This TV was purchased in2005. I cancelled my cable and I just hooked up a digital antenna but the TV isn't finding any channels. What do I need to do? I was...


HDTV indicates the number of lines that are shown by the TV. (HD means that at least 720 lines can be displayed in a given picture.) To receive OTA signals, you need an ATSC tuner (digital) of sufficient power (with a clear path to the transmitter) these days. The RCA D52W20 was released in 2002 and only has an NTSC (analog tuner). You will need a digital-to-analog converter to receive OTA TV (unless any low power analog stations remain in your area).

Please note that the basic digital-to-analog converters that were available with the government coupon back in 2009 were SD (480i lines of pixels used) units. HD d-t-a converters exist but are more expensive.

I hope this helps.

(the phrase "digital antenna" is meaningless; check with tvfool.com or antennaweb.org for the direction of local transmitters. TVfool.com will give more information on the type of antenna (indoor, outdoor, amplifier) that you will need to receive channels in your area. Antennaweb assumes an external antenna but is very conservative in the stations that it will indicate that you can receive. Antennas are given a color rating based on how far away the transmitter can be to get a watchable signal. Since digital signals are either enough for the tuner to interpret or you get a "no signal" message, you often need a stronger signal than was needed to receive a watchable analog channel.)

I cant get any channels with my coby tv


This COBY only has an analog tuner. Thus unless you are close to one of the remaining low-power stations, you need a digital-to-analog converter for OTA TV signals. For digital TV, you should use antennaweb.org or tvfool.com to identify the antenna and direction for the digital signals that you may be able to receive. Antennaweb assumes an outdoor antenna is conservative in the channel list it provides. Digital signal is either enough to register with the tuner or No Signal. An amplifier may be needed is the signal is split to several TVs.

If you have cable, check the type of signal coming in to the TV. If the signal has been switched to digital, you need a set top box.

I hope this helps.

Im trying to hook my standard antenna up to my jvc av 56p585. i dont have manual. and i cant get any channels. what do i need to put my tv on to get my basic local channels


This JVC TV has an NTSC (analog) tuner. So it can only receive some of the few remaining low power tv stations that are still using analog transmitters. Depending on your location, you may not have any of these stations within the range of the antenna.

You need an digital-to-analog tuner to get additional channels. Use tvfool.com or antennaweb.org to check for stations in your area and the appropriate direction to point that antenna. (You may need an amplifier since digital stations are either sufficient signal for the tuner to use or you get "no signal".)

Please note that the d-t-a tuners that were available with the government coupon cards only handles standard definition signals (480i). The HD tuner digital to analog converters are available at some online sites but cost more.

I hope this helps.

(you can use a tuner in your computer (USB or PCI card), but you will need a converter unless your video card can put out a signal other than RGB. The HDMI port on the TV will not interface directly with a computer.)

HP pc with built-in tv tuner


Have 9, 5 and 13 turned entirely digital as yet, so as to leave you without their signal?

From what you say, the tv tuner in your HP receives analog signals better than or instead of digital signals the stations you can receive may be analog while 9, 5, and 13 may have dispensed with their analog transmitters.

They don't have to until June, since the changeover was delayed from the original February cutoff date by Act of Congress. It is actually easier to receive a digital signal than an equally powered analog equivalent so the fact that your system worked so well with analog signals bodes well for the efficiency of your indoor antenna arrangement, though you may have to replace the possibly analog receiver in your pc with a usb digital thumbdrive like model to continue after the changeover is final.

Here's a tip...if the receiver in your pc resembles a square aluminum tin can, mounted on a PCI card in one of your slots, it is very likely analog and not digital.

Usually these receivers (or actually TUNERS) are heavily sheilded while digital receivers do not require the same amount of sheilding to avoid interference with other components, which is the concept of the big square tin can, that a digital tuner does not require.
