Getting a no signal message on all tuner channels

If you are getting an OTA signal, you should check your antenna, any amplifier or splitter and the station's status. The "No signal" message indicates that the signal is not strong enough to be resolved by the tuner.

1) Is your antenna pointing in the correct direction? Outdoor antennas can sometimes turn in the wind. Reset the antenna to the correct direction.

2) If you have a splitter dividing the signal between TVs or other devices, try a direct connection to the one TV that isn't receiving the channel. Similarly, if you have an amplifier in the system, try using the antenna without it. (I have seen an amplifier become a filter for select channels when damaged.) The only solution is to replace the device or omit it. (In my case, some channels require amplification; thus we replaced the amplifier.)

3) Has the station's local transmitter/repeater been damaged? Check their news feed. Towers fall and transmitter components can fail.

You could try and see if another tuner picks up the signal. Some low end tuners are more sensitive to signal strength. If you are getting the station from another source, check with the provider. We recently lost some of the local PBS stations due to problems with the cable provider's feed. Only one TV is connected to the set top box.

I hope this helps.

If you are seen this message when Channels are selected, it means the RF cable is bad, or Tuner is bad...if you are seen this message with any other input (HDMI, YPbPR), there is something wrong with connection cable or external equipment. If it's with both (Tuner or External equipment), then TV is the problem.

Tuner is ng. You can check out the repair cost but ......Another option is to buy an external HD tuner and feed that signal to your set via HDMI inputs. Cheaper than a repair.

Yes, you will need an antenna to get live OTA TV. The Haier HL42XR1 has an ATSC (digital OTA) tuner and a NTSC (analog OTA) tuner. Your location and distance to the local transmitters will determine what type of antenna will be best. See antennaweb.org or tvfool.com and enter your address. TVfool.com gives a full list of all stations you may be able to receive depending on your antenna (indoor, outdoor, height, direction). If you share the signal from the antenna with another device, you may need an amplifier to maintain the signal strength. (Warning, when amplifiers fail, the signal can become worse than the unamplified signal. With digital TV, signals are either strong enough for the tuner to understand or a "no signal" message will appear.)

I hope this helps.

No the Tuner doesn't have an Output, so one cannot get a signal OUT of the Tuner, UNLESS there is a Tuner Out, A Monitor, OUT. Then you cannot get any signal to feed into the device you wish to record with. The signal MUST go to a TUNER first, then the OUTPUT may be fed to anything else. As said IF the Device with the Tuner HAS a way of outputting Video & Audio, then you can take that signal and record it, otherwise you cannot.

For tuner problems, especially the digital channels, you should check for a TV firmware update at www.sonystyle.com. I was having some strange loss of digital channels on our 40" Bravia, starting with channels only appearing for a second before the screen produced a 'No Signal' message. After we tried the automatic retuning, then we could not even get the one second signal. None of this appeared on the description of the download. However, we downloaded the patch to our PC, loaded the file (19 MB) onto a small flash drive, which we then used to upgrade the firmware in the TV. All our digital tuner problems disappeared!!

You must have a tuner, but the one built into the TV will work fine. Have you scanned for available channels after connecting your antenna?

If the tuner is bad, changing the mainboard should fix the problem.

Hi.
The information provided shows that tuner 2 isn't working at all on at least the selected channel. This could be a problem on just some channels with this tuner or possibly all channels. You can verify this by hitting the "SWAP" button on the remote to switch tuners while viewing a live program on a problem channel. If you choose the same channel for each tuner, I expect you will see program on one and "one moment please" or freezing or pixelation on the other. The confusion about recording comes about because of how the DCT6412 chooses which tuner to use for recording versus viewing. If you activate record on a channel you are watching, it will use that tuner. If you see it, it will record. For future or series recordings though it will automatically choose to use the alternate tuner so that it won't have to change your channel selection. Since there is no input signal detected on the other tuner, it will actually record but there will be nothing to see on play back. What causes this? It is probably that tuner 2 has failed. There is a slim chance that your cable signal coming in is either too strong or too weak but this is unlikely since the DCT6412 splits and then amplifies the cable input signal before distributing essentially equal signals to both tuners (the plug on coax adapter on the back feeds the cable signal to an AGC amplifier within the DCT6412 and then splits and distributes that output to both tuner inputs). You could check the OOB AGC level as described here http://www.cable-help.com/ but I think your problem is more likely that tuner 2 has gone bad. JM Belleville Ontario

Since it has voice or sound then I don't suspect the tuner but probably the tuner does not have the 33 volts that goes through r106 location number on the board. It is a 27K resistor and can be bought for about a dollar at Radio Shack. (pack of 2or3) A repairman or someone experienced in electronic soldering and desoldering can change it easily. Could cost around $50 to repair depending on the serviceman. If it has rca jacks (red, white and yellow) The tuner can be bypassed if you have a cable box that passed these signals: audio left and right and video. Hope this helps
