No signal when connecting PC to TV

Hello,
I've connected the RGB cable from the motherboard to the TV (LG 42PX5D), fixed resolution/hz properly... and selected RGB on input, yet the television screen still says no signal when I turn the PC on. I am really puzzled! Hopefully you know why =) Thanks No RGB signal message connecting laptop to VIZIO HDTV

    I have an RGB cable hooked up from my laptop and into the RGB jack in the back of my Vizio television. After selecting RGB as the input, the message "No RGB signal Power will be turned off" appears on the tv screen.

This happens to almost every laptop I know. Here are several solutions:
1. You need to manually enable video on tv by pressing two buttons on your laptop keyboard. The first is "Fn" (at the left bottom). The second depends on your laptop manufacturer. Look at the function keys. F1....F12 for the LCD/CRT or the corresponding sign. Press and hold Fn and press second button. Sometimes you need to press second button several times. This means you need to cycle through all available options to enable Laptop's screen and TV screen at the same time (clone).
2. Intel Extreme Graphics video cards sometimes doesn't support a procedure described above. You need to find intel video card options manager running at the sys-tray (right bottom of your screen near the clock). Right click on it. Select Graphic Options -> Output to -> Laptop + ... clone (or something similar)
Note that not all video cards are capable of showing the movie on media player at the same time. You need to choose Laptop or TV

Just bought a new smart tv and my panasonic recorder keeps saying not connected - why


Usually this message is because there is no direct connection between the recorder and the TV!

where do you see the message, if on the recorder then check cable connections! if on TV then turn on the recorder!

The color on my TV is all pink. I have tried a hard reset but it didn't help.


Your TV has lost a GREEN color from a basic color palette (Red-Green-Blue). It is often caused by:
- damaged LCD cable (which connects the display with a signal board inside the TV),
- damaged video signal cable (ex. SCART, HDMI, VGA),
- damaged video processor (on the signal board).
I can't give you a more accurate answer, because I don't know what is your TV mark and model and, in what situations you have the problem.

I have checked cables and different methods of connecting, but the white and red audio out of my PVR appear to have stopped putting out sound.


Go through the setup of the PVR and check the sound settings. It sounds like it's only producing digital audio, that's why it works with HDMI but you want analog, so set the audio to stereo, or try every setting to see what works!

How could I connect a Daewoo 42sm TV?, I can't afford cable so I use a converter box(analog to digital w/rabbit antenna)on my other TV and I was given this Daewoo TV and would like to watch it;please


If your converter box only has RF outpit connectors "F" type screw on it looks like this my be more of a monitor then tv.I took a quick look at the manual and didn't see any RF inputs so it appears it doesn't have tuners built in Looks like you'll need a box that has RCA output connectors.or others that will match what the monitor has on it for input types

I have a toshiba LED TV Model 40PB200, i bought it two months now. Recently, the audio in port started producing a sound as if microphone is on and the VGA for computer flickers when i connect a laptop on...


One thing is that unless it is usb you should always have the devices powered DOWN before connecting them via" wire electric data cables". it only takes 3 static volts of electricity to damage a circuit board. when you zap you buddy when you wear sox its 20 to 30,000 volts of static electricity so 3 volts would not be known let alone felt or seen. Power down and you will be well not you .

My tv has gone some orange colour


Try unplugging your tv and anything connected to it - you might want to take a picture first so you have a reference. I would also unplug everything connected to the tv: cable, stereo, etc. Wait a few minutes, then plug in and re-connect everything.

You can also go into your TV's setup menu and adjust the picture settings - try restoring the default settings first.
