Replace tuner, get number and order from MCM, or Bluestar-online, Tritronics.

I cannot set up my tv, after it had cable. when i try the setup program the tv will not accept any channels and sap appears on the screen. i want go back to uhf/vhf, can somebody help me.

If you are in the US, there is no logical reason to go back to UHF/VHF as there are no broadcasting stations using the analog frequencies anymore. Those old tuners will not decode anything that is coming over the airwaves. Thus their channel scans will not detect ant channels, making you think there is something wrong. You would need one of the digital converter boxes sold during the transition period and then you will only get your local channels, much as you would have before.

I have a wf24t5 that i want to connect to a dish sat hd. how and what do i need to do to connect?

After confirming by viewing the operation manual for this unit, this TV is only capable of inputting a baseband video and standard audio. Unless the Satellite Receiver you have has those type of output jacks then this TV will not be able to reproduce picture or sound from the Receiver. It may be possible to connect through the antenna connection but again the Satellite would need a connector that would output on Channel 3 or 4. Most recent satellite receivers do not offer these ouputs. You indicate that the Receiver you have is High Def. The TV you have is not high def and would drastically down grade the quality of your picture and audio being delivered by the satellite receiver

I can't program my tv to regular antenna channels

You can program to regular (analog) antenna channels. To do so you must use the original remote which has a TV/DTV switch in the top right corner of the remote. Choose the appropriate mode for the type of channel you want to see or scan for. Here is a link to the owners manual and a picture of the remote swithc. The info on the signal switching is on pg.13.

I can't get FOX on my converter box--what is the channel # for FOX?

It could be your antenna. Some retailers sold consumers UHF-only outdoor antennas and not VHF/UHF combo antennas. Other outdoor antennas may not have a power boost included for the VHF antennas (rabbit ears). The new DTV signals from stations are now broadcasting in lower power signals than before June 12.

Outdoor Antenna

KMSP/FOX 9 and KARE 11 both broadcast on VHF signals. WCCO and KSTP broadcast on UHF signals. You will need a VHF/UHF outdoor antenna to pick up KMSP and KARE 11 and also get all the other channels.

Indoor Antenna

Check your antenna to make sure it's a UHF/VHF antenna. You may need an indoor antenna that has rabbit ears -- that is the best way to get KMSP/FOX 9 reception on your TV. Your antenna should have a power boost to amplify the VHF signal if you are having trouble getting FOX 9 or KARE 11.

What Antenna Is Right For You?

Make sure you antenna is pointed toward Shoreview, where FOX 9 transmits from.

Skips past all channels after 13. CableVision

I don't know the exact step to set it because I don't know you model TV. When you go to menu set channels it should give you the option to choose cable or air. If you pick cable all your channels will be in VHF which is what you want. If you pick air the first 13 channels will be VHF and the rest will be UHF which cable don't work on. After you pick cable then auto program and you should get all your channels.If this helps you and I hope it does give me a vote please.

Tuner will not pick up cable box on channel 3, front and rear AV

In order for the TV to work with the cable box by using a piece of coax and tuning the TV to channel 3, you must make sure the TV is in "Cable" mode on the tuner and not "AIR or Antenna" the frequency maps are different between these types of service and channel 3 cable will not be the same as channel 3 on Air or UHF/VHF.

Often there is an auto program feature on TV's that will "scan" for all available channels, and this should select the proper input type.

Hope this helps!

You may need a stronger antenna or your neighbor may have only a VHF antenna and most of the digital channels are being broadcast over UHf. . First, though, check the antenna connection as if they are dirty, they may be lowering the signal strength (these are the connections at the antenna). Check for the angel to put the tv antenna at to pick up the most channels. Internal antenna work very poorly. I have been having no problem with my outdoor UHF/VHF antenna, it picks up the same amount of channels in analog and digital.

No uhf with antannae

UHF channels are basically "line of sight" type signals. You need to be pretty near those UHF stations.
You need a Uhf or combination Uhf/ Vhf antenna to receive them - - Usually an out-door type.
Your TV needs to be set in the "antenna" mode to tune beyond channel 13 "air type" channels. Channel 14 is the first UHF channel if you're in the antenna mode. If you're in the "Cable" mode then channel 14 is a cable channel which is operating at a different frequency from UHF.
I hope this will help you!

Reception of vhf/uhf channels

You did not mention which set you have, so look for a small switch (usually on the back of the set) or go into the menu and set the TV to the "broadcast" or "tv" mode. If the set is in the "cable" mode, you will not get any UHF channels above 13.

Channel set

Apparently your TV is set to the "standard TV" position. Before you auto program your set, set it to the cable mode and then do the autoprogramming. In the standard TV setting, you just get off the air channels 2-13 vhf and 14-83 uhf.where as in the cable mode you get vhf channels 2-13 plus your cable channels. Stargazer
