How do I add the HD channels picked up my HD antenna to the master channel list on my Visio TV?


Hello, with the set on, press the menu button, move the cursor down till the "Tuner" section is hi-lighted, click on it. Then the first selection is "Tuner Mode" click on it, the choose "Antenna" click on it. Then move to the "Auto Channel Scan" and click on it, and let it set all your channels. when done, just exit menu and change channels as desired. you can go to page 39 in your manual for these instructions: Tuner Mode
Select Cable or Antenna depending
upon which equipment you have
attached to the DTV / TV Input.
Auto Channel Search
Automatically search for TV channels
that are available in your area. Be
sure to first select the correct tuner
mode above. The TV will search for
analog and digital channels. When the
search is done, press EXIT to begin
watching your programs. thanks, Terry

No picture no sound


Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)?
If that is the case, maybe vertical IC failed or loose connection.

Hi it's me again the gal who dropped her tv


Yes, you should still have sound, providing that you have an antenna connected and are tuned to a channel. If you have a vcr or dvd player to hook up to it try that and see if you have sound.
No sound while viewing a tuned in channel or via a vcr/dvd player is not a good sign. It may have cracked the PCB inside the tv. A cracked PCB, depending on the severity, can also be repaired.
You really won't know the severity of any internal damage until it is opened up and checked over.
Is the line on the screen Horizontal (left to right) or Vertical (up and down) and is it centered on the screen? A vertical line would indicate that it may be a cracked PCB (Printed Circuit Board).

Cable setuo for model 27r410t


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.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

No vertical deflection. Vertical output IC, caps.

Horizontal multicolored lines appearing


Open up the TV and unplug and re-plug the connectors to the circuit boards. This is most often caused by a poor connection of the circuit board connectors.

Picture is snowy on every channel. I hooked up my playstation and set it to the correct channel but the screen display is the same. I tried using the menu and the menu comes up just fine. The menu goes on...


If one tv looks good and another one dosent look good or operate correctly then we know for sure that the problem is not the antenna. Now the menu comes up ok because the menu is injected after the tuner into the video curcuit from a osd or microprocessor. sounds like you could have a defective tuner or antenna block assy.
