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?

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.

Hello, If you are using this combo with cable and the channels just coming through, you will need to replace the tuner(mounts vertically on the main board and it's located directly behind the cable/antenna connector). If you are trying to use this TV with a set of rabbit ears, the free signal channels turnes digital last year and that is why you get nothing. The tuner as an assembly is still available from a couple of sources: Partstore.com and Union Electronics(firstname.lastname@example.org)
What is your signal source, OTA or cable? Did lightning or another type of power surge recently hit? Make sure you have the TV on the desired input.
If OTA check your antenna direction and that you have the Channel Setup (from the menu) set to Antenna. Also check if you have the right antenna to get stations in your area. Antennaweb.org gives the most likely channels and directions. tvfool.com will give more detailed information and more stations. Both sites assume outdoor antennas but the direction information is always good. Look for new construction or big trees that might block the signal. Do you have multiple TVs sharing the same antenna? You might need an amplifier.
If cable, check the Channel setup. Check for someone recently damaging your cable installation (cutting the wires, trying to split the signal to get it for free) Splitting the signal to multiple TVs may also be an issue, get an amplifier of the correct type. Some cable systems may require a bidirectional amplifier.
If you recently had a power surge, see if the TV works with other inputs. Tuners can be replaced if the TV is worth the labor costs for you.
I hope this helps.
Cindy Wells ( My household had three tvs and a digital to analog converter that lost
their tuners after a nearby lightning strike. We chose to replace the
TVs since two were over 15 years old and the third was also out of
In most cases when you set your menu ("tuner section") to cable, the tv will pick up all channels, but if you set it to "off air" or "antenna" (or whatever the other choice is labeled), then the tv will only go up to about channel 50 or 60. Are you using cable, dish, or an antenna on top of your house. If using cable or dish, then go into the menu on your tv and set the tuner to "cable". I am pretty certain that your tuner is NOT currently set on "cable" and that also there are no local "off air" channels in your area on 2 thru 6, therefore, you see snow on these channels. I have repaired hundreds of tv's and I feel very strongly that your problem is in your menu.
Get an antenna hooked up, even rabbit ears should pull in a few analog channels. Set top boxes will only output Ch 3 (switcheable to ch 4 on the back if needed) and cable may be dead or only give you scrambled CATV channels. You need to set your tuner to "antenna", not CATV, IRC,HRC, or ATSC (if you have a digital tuner) and do the setup again. You could have a bad tuner at worst, and all is not lost, just hook up a VCR via RCA cables and use the VCR tuner to change channels. Keep TV on Ch3.
Make sure in the on screen menu that the tuner is set for CABLE or AIR
depending on whether you have cable or an antenna. The channel
frequencies are the same for ch 2 thru ch 13 but everthing above that
is different depending on your source.
Hope Ya Fix It!
First check to make sure your coax cable is in the correct slot, (Make sure it is plugged into the outside port). The other port on there is the ATSC antenna which would only be useful for over the air broadcasts if your area has them (I believe Omaha, NE would be able to get KETV over the air)and if you have an applicable antenna.
You are using the proper format (NTSC_M), if you are using the WinTV application, on the upper left side of the screen you will see your channel up/down buttons, in-between them is an addition button for video source, try changing this to see if you are able to scan more channels. My initial reaction is that you are using the ATSC tuner for scanning the channels.
I will check back frequently to check for more information for you.
