Question about RCA HD50LPW42 50" Rear Projection HDTV

1 Answer

Can't get any channels on the air.\

I have an RCA HD50LPW42 and just recently the tuner seems to not be working. We only have an antenna(no cable). The DVD/CD player works just fine when set to that imput. When using the up&down buttons on the remote, it does nothing I can manually key in channels with the remote, but still nothing shows up on the screen. Any ideas? I'm thinking the tuner might be the problem. Would that be an easy fix, or something I'd have to get a tech to look at? Tom

Re: Can't get any channels on the air.\

If the tuner is the problem then it is a very bad problem as the tuner is part of the DM module and that is very expensive. When you say you have to manually key in the channels, do they work then? If so the problem is not the tuner. If your only problem is that you cannot go from one channel to the other by using the channel up and down button on the remote, then you have most likely just lost the programming on the tv. Go into menu and set up and find the auto channel programming and run auto program to correct the problem.

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 or for the direction of local transmitters. 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 don't know how a program it, since you change digital.

So far as I know the HLN series does not have an ATSC tuner, thus no over the air (OTA) reception. You can probably still get a $40 coupon for an OTA ATSC to NTSC converter. Note that will NOT get you high definition (HD). With Dish you can get HD receivers that do get OTA ATSC both HD and SD. With Direct, no OTA AFAIK. With cable you would need a QAM tuner, not in your TV AFAIK to get clear channels as required for locals. Otherwise cable needs a Set Top Box for digital and scrambled channels although the standard definition (SD) non-scrambled channels work with your NTSC tuner. Too bad there seem to be no ATSC to 5-cable RCA or HDMI HD converters except Dish. -Ken

HD50LPW42 screen is black with antenna inputs

It sounds to me like you have a tuner issue, I have seen this before. If you have a good picture from other sources and they have the same antenna input, the tuner is suspect.

I hope that this helps you solve your issue.

You need to have a set top box.

By law, as of March 1, 2007, almost all televisions should include a built-in tuner (called HDTV, digital, or ATSC tuners) that can receive high-definition programs over the air by simply connecting an antenna. Your HDTV doesn't have such a tuner, you'll need to connect an external tuner (or cable or satellite box) to watch high-definition programming. External over-the-air HDTV tuners currently cost at least $150.

To make it easy for you - you should have original remote.
Then through the menu look for channel set up then make sure you select cable or antenna then you do autosearch(sometimes called autoprogram).Unless the tuner is defective,you should be able to program withe the original remote.

Doubt it. We ran HD through our small CATV system using consumer grade modulators but could only get them on the AIR frequencies, as we had very limited bandwidth as we had to carry 64 analog channels plus digital HITS packages for our Motorola DSxxx series boxes. Try plugging the CATV feed into the ANT input and do an autoprogram, or tell the tv to look on the AIR frequencies when it asks if you have CATV or AIR. Worth a shot though.

Weak Signal ..

Sounds like you have a bad tuner. The most likely cause on these RCA's is a loose RF antenna input connector. A bypass for now is if you have a VCR use it as the tuner and then connect it to the TV using the composite video inputs. If that faisl as well then you have a bad signal board.

Broken cable connector

the easies and cheapest way is to use the audio video input. pulg the cable into your vcr & use the vcr to change channel. the other way is to replace the tuner, typically tuners sell for around $75.00 to $100.00.
