    DTV input gives a blank screen. All other input areas work great. I have tried the system reset--no help. I noticed poor response on the remote AFTER selecting DTV as an input. For now, we are using a set-top box ASTC tuner--but would like to get the Vizio ASTC (DTV) tuner working--it picks up remote channels better than our substitute tuner

    Mine is doing the same thing but once it warms up the DTV tuner works.

    Same problem on a 3 year old Vizio GV46LHDTV - we get the same black screen by selecting DTV, and then the remote is TOTALLY non-functional - we have to use the buttons on side of the panel in order to get back in operation.

    I have the same problem. It started about a year ago. It would happend about once a week. Eventually it was every day. Then it would work only after the TV was on for a minimum of 3-4 hours. Now it no longer works at all. If you are tired of using the side panel buttons, use the INPUT button on the TV remote. A service tech from a local firm has told me that replacing the main board will solve the problem.

Lone_Heckler -- did you get a part number number for the "main tuner board"? I have the same issue and would like to try fixing it myself...

Well mine is now fixed.

$250 for the main tuner board and another hundred for labor.

I did find that there are some "like new" boards out there from otherwise damaged units. For instance a Big Box store damages a flat screen or exterior trim, the board is removed and tested.

The "like new" boards I found are about $150 with a 90 day warranty. The new board also has 90 day warranty.

The tech guy that posted here was correct. Thank you.

    To DREW412
    I don't have the reciept but I can see if the part number is on it. The service tech told me that Vizio is now making parts available for on line order. I believe my tech bought the part from an East Coast supply house.

The DTV input in my GV46L stays black. Why?


You don't say what you are trying to input but take note that your model does not have a digital tuner on the DTV input. If you use a digital OTA antenna, the signal must first go through a digital converter or tuner before it goes into the DTV input. The DTV/ANT input is only cable ready. There is no digital tuner in the TV to activate the DTV menu.

I have a Sharp Aquos LCD TV Model LC-32BX6M , when I try to connect a new generation Android TV Box HDMI Out to TV's HDMI input the Android Logo appears and after sometime the screen goes blank t


im not sure but could it be a comparability issue with the device and the wake up signal from the device to the tv? android systems use a Linux based file system, so the problem may be in the tv's input settings. hdmi input from the device to the tv. and then go to tv input mode and see if putting the device in another hdmi port doesn't work.

How do I connect my PS3 to my sanyo dp50747 in hdmi? I have everything hooked up correctly, but its not coming up on the TV. What do I do?????


If you see a no signal message, then it means that the signal output format of the PS3 does not match . It happens if you have previous used it on another tv and now connected it to a different tv. To resolve this, turn off the PS3 . Press and hold the power button on the PS3 till you hear three BEEPS. The PS3 should automatically detect the tv's resolution and the initial setup screen should appear. After that you should just follow on-screen instructions to set it up.

How do I connect my Sansui 6010B VCR with an analog TV and a DTV tuner?


two ways of connecting VCR with Analog TV with DTV tuner.
DTV tuner (RF) output to VCR (RF) input,VCR (RF) output to analog TV (RF) input.
turn DTV tuner on (VCR should have a TV\VCR switch that makes signal coming from tuner BYPASS VHS right into TV) note:: change channel FROM tuner.You should be able to record by placing a blank tape and pressing RECORD.
2ND. DTV tuner, VCR, should have a RCA in\out connections...Audio & video.You need a RF\RCA bypass switch. It has a INput with RCA connections to a RF signal out that goes to the RF Input of analog TV

Screen goes blank and message comes up saying "input signal out of range"


When does the screen go blank? Also what do you have plugged into it this most likely just because your input signal may be set at to high a resolution or frequency. Once I have more information I can assist you further.
Thanks,
Lee

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

No signal


You have changed the input to a selection that does not have a signal. Look at where the cable goes into the TV, this should show the name of that input, then change input back to that exact one via your remote.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
