You may want to try another channel auto scan after it starts working. The most likely cause is the main signal board or a slow pwer supply line to it

    You will need the main board containing the digital tuner replaced........if you are technical,I can guide you furhter........you can search your model at shopjimmy.com and see if they have a salvaged one. Alternative would be to circuimvent the problem by using a cable box hooked to the main cable and thru the component or HDMI inputs on the tv. A dvd recorder with a digital tuner may do the trick as well!!

Do you know if the Visione VISLCD2408 TV has a BUILT-IN DIGITAL TV TUNER or does it only have a ANOLOG TV TUNER ?


If you can tune digital channels directly, e.g., 10.1, 29.2, the tuner is built in.

Using a cable splitter i have one cable going to the modem and the other going to other tv. The problem is the other tv is stuck on one channel that is different than the first tv


Most cable systems today scramble their digital signals in such a way as to require the use of a "cable card" (for TVs that support them) or a set-top decoder box. Hooking up directly to the cable on most cable systems today won't get you much of anything in the way of channels regardless of the type of tuner you have installed. They do this to ensure that you are paying a fee for each set that is connected to the cable (the rental fee for the card or box).

GV42L vizio tuner


Your vizio has an internal digital tuner. When you are on air, make sure that it is set up for digital. It might say DTV. Some sets have an analog only and digital only program option in the user menu, or as a seperate input. When in doubt, check your user manual.

I am trying to hook up a digital labs, 19'' lcd tv/dvd combo and when i do the initial channel scan it doesnt pick up anything from the satelite at all, i have hooked them toghther anyway i can think of...


Most HDTVs have ATSC, QAM and NTSC (analog) tuners. It sounds like yours does not have an NTSC (analog) tuner. QAM tuners only pick up digital cable channels. You may need to switch to your cable company's digital service if your not already on it. Call your cable company for further info

Have a vizio lcd tv . can not get any channels today with the switch over to digital. i use an antenna


Your TV probably does not have a digital tuner connected to the DTV/ANT input. Mine didn't. I had to connect the digital antenna to a digital converter box THEN go to the DTV/ANT input. Only then would it activate the DTV menu and allow me to scan for channels. If your TV worked fine with Cable TV connected to the input, it was because your signal was coming from the digital tuner in your DVR, or your cable provider was sending you an unscrambled digital signal (not likely).
I used a digital converter box I had purchased with the government $40 coupon back in 2009 but the resolution is only 480 and looks like a Monet or Renoir. Now I am shopping for a high quality tuner.

Sony KDF-E42A10 42" - Do I have to purchase a converter box?


Yes this tv does have a digital tuner. To engage it, you must have a out doors antenna. Go to channel setup and do auto program for both anolog and digital. link

VCR tuner cannot tune in my cable channels


It is working as designed. The purpose of your cable box is to take in a wire containing all of the possible channels you might watch, and then extract *one* channel, and force it to appear as channel 3. If you connect the cable directly to the VCR, then the VCR's "tuner" (ie, channel selector) has an opportunity to extract any channel it wants. But... as you point out, your VCR won't be able to "see" any of the digital channels. So... if your goal is to be able to watch any of the digital channels, the signal must pass through your cable box, which will put the selected channel on channel 3. There is no value in going from the VCR to the cable box, since the VCR's tuner will have already filtered out all but one channel. It would be helpful to make a list of what your useage goals really are, since there are so many different ways to hook these things up. Are you interested in: - watching digital channels? - recording digital channels? - watching one channel while recording another? - using higher quality video signals (composite, s-video, component, etc) rather than RF (ie, channel 3) And so on. Keep in mind that you have *three* tuners: Your cable box, your VCR, and your TV. It sounds like only your cable box can tune in the digital channels. If your cable box puts out any non-RF signal, then the best choice would be to go: Coaxial Wire -> Cable Box -> Video Connection -> VCR -> Video Connection -> TV, with the VCR and the TV both set to "video". Then you would only use the cable box as a tuner, the VCR would only see the tuned channel (via video in), and the TV would see the same channel (or whatever tape you are playing) on its video input.
