    Same problem. The monitor cable seems to fit into the RGB input of the Vizio 37" HD LCD, but no signal.

    Ours did this at first, but we unhooked everything, found out we had a lose connection. Reconnected everything and now it works great except, after watching for about 20 min the laptop goes blank (even though there is no screensaver on) and you have to shake the mouse then it comes back. We have a vizio tv as well and a dell laptop

Where to connect my pen drive in my sony bravia lcd klv32s400a?


Hi Radhika,

Your TV has USB port on back side. Just plug your pendrive there. Then go menu on TV ( use your remote commander) and go to this input. Your TV will read the file on pendrive accordingly.

No signal is the only thing that will come on my TV


What is the signal source? How do you have the TV connected to the source?

For most video equipment (dvd players and other set top boxes), connect the TV to the device with everything turned off. Turn on the TV then switch to the appropriate input. Finally turn on the source device.

Check the cables to make sure that they are fully seated. Try using different cables (to rule out damaged cables).

If your source is OTA antenna, check that the antenna hasn't been rotated. (This assumes it has worked in the past.) Check your wiring for any damage. If you have an amplifier or switch in use, remove it and check if the signal comes through. (You can use a coax coupler to connect the two wires directly). If the signal is fine, replace the amplifier. If you were using a switch, either replace it with a direct replacement or with an amplified switch (in case the signal was reduced beyond the level that the tuner can receive). Also check if the fuse has been damaged, if you have a surge protection/grounding system on the antenna system. Replace the fuse if needed (this can also be the issue for satellite and some cable installs).

If your source is a computer, try a different video cable. Turn off everything before connecting the TV to the computer and turn on the TV first when ready to restart. Make sure that the video port that you are using is active. (Desktops often have on-board video and separate video cards. Only one set of ports is live.) Depending on the computer, you may need access the BIOS with the computer connected to a different monitor to change the active port. (Press Esc, F1, F2 or F10 depending on the machine immediately after turning on the computer. Sometimes I miss the timing and have to shut down the computer a second time and repeatedly hit the key to access the BIOS.) Make sure that the computer is sending a resolution of 1360x768 at 60 Hz.

If you are connecting a computer to the TV with an HDMI cable, try using the VGA (RGB) port instead. The computer's signal is not the same as that of other video set top boxes. This TV does not support a computer on HDMI.

For a laptop, you also may need to enable the external video port. Then set the OS to use the external port. (On my HP laptop with Windows 7, I can do this by right-clicking on the Display and choosing Graphics Properties. Then I can set the monitors to Dual, Extended (mode) and Laptop monitor or External Monitor (display). Then click Apply followed by OK (in a second window) to accept the changes. For other laptops, you probably have a shortcut or can do it in the OS.

If the problem occurs on all sources, the input board may be damaged on the TV. (A power surge (lightning strike) could cause the damage.) If the TV is under warranty, you should contact Vizio.

Since the inputs are directly soldered to the main board on this TV, unless you are skilled at soldering, you would need to replace the entire board. Disassemble the TV and check the current board before replacing. There are several main boards available for the TV. Shopjimmy.com lists the VA220E parts as out of stock. Partstore.com has some of the boards in limited numbers: http://www.partstore.com/Model/Vizio/Vizio/VA220E.aspx .

I hope this helps.

How i am connect Wi Fi or internet to my TV.it is vizio and model number is J V 50 P HD TV 10 A. and Serial number is PHLANCJ2804679. I WANT CONECT WITH INTERNET FOR NETFLIX PLEASE LET ME WHAT CAN I DO.


As I type this, I am using my Vizio 50" plasma. All you need to do is ditch your current monitor you use for your internet service and use the same cord from the monitor to plug it into your RBG port on the back of your tv.
Next for sound there is a 1/4 jack next to the RGB port on your tv. Connect your tv to your audio out on your computer. (headphones or aud out)
Select RGB on your tv, and your good to go. I bought a wireless keyboard and mouse for my computer which makes it more convenient.

NO RGB SIGNAL - VIZIO HDTV TO LAPTOP


I've been online looking for a solution to this problem and couldn't find a fix until today. I just got off of the phone with a Vizio Tech. He told me that some pc's have a way for the monitor to show the screen externally, and that there's usually a button, sort of like the input option on your TV but its an output button for a laptop in my case. It should look like a picture of a TV in and out of each other. Mine was located on the number four key. I had plugged in my wires and put the TV input on RGB. then on my laptop pressed the function key and number 4 key at the same time and what do you know, I had a picture on my screen. I almost gave up on my vizio but love it even more now. I hope this helps.

Connecting laptop to lcd


You may need to use the S-video cable for video. Make sure video mirroring is disabled on the powerbook. Also, make the external monitor the primary display by dragging the menu bar to it in Displays preferences (Mac OS X) or the Monitors control panel (Mac OS 8 and 9).
