Question about Sharp LC22DV24U 22 in. LCD TV/DVD Combo
I just bought a two way vga cable from a computer store and the guy had assured me this cable would allow me to hook up my laptop to this tv, although without sound I'm not worried about, but the tv just says "No signal" even though it's on Input 4, PC station, if you will.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

SOURCE: My Sharp Aquos 46" LCD
Digital inputs on Aquos TV's are "always on," usually the HDMI inputs and DVI inputs. As opposed to analog inputs 1, 2, or 3, are only activated once something is plugged in.
Try plugging in another HDMI sources into input4 or 5, if its still not working, the TV needs a new Main Board. Try calling Sharp 1-800-237-4277 and locating a local service center in your area.

I would check the video setting on your laptop. The resolution or refresh rate might have been changed and the LCD TV might not be able to process the signal. Try changing the laptop's resolution to the lowest setting(right-click on desktop and pick properties) and see if the TV produces a picture. Also verify the video output on the laptop is working by hooking it up to a computer monitor if available.

There are a number of things to check here:
1) Verify that the resolution on the PC is set to a supported level for the TV. Usually the TV will show "no signal" if the resolution is out of range or the message "out of range" will appear.
2) You don't indicate whether you are connecting to a desktop or laptop. If a laptop, you may need to turn on the external monitor. This is done by using the function key and either F5 or F6 (the key should have a picture of a screen on it). Hitting this combination will toggle between the main screen with.without the external monitor.
3) Verify that the TV port is selected correctly (AV1,AV2 etc)
4) You will need a separate cable or the audio regardless of the system type. Also verify that the audio cable is in the corresponding audio input jacks for the video option selected.
If you have completed the above and it still doesn't work, please post the details about the computer being used and the exact cable setup that you have and I'll check into this further.
