No PC Signal

When I turn on my TV it says No PC signal then counts down from 10 and goes on standby. It wont let me change the source or bring up the menu. When I hook up my PC to it the image is displayed but I still cannot change the source. Can anyone help me asap? My tv started this "no PC signal" today after I unplugged it and mounted it to the wall. It was working fine 20 min. earlier. Any solutions on what to do next??

SOURCE: Olevia 242T 42" LCD HDTV - Suddenly No Picture, Nothing Works

 I heard they were restructuring their company or something.
There has been a change ownership from Syntax-Brillian to Olevia International Group.
Details of Olevia brand  
Unfortunately for all of us (we have 747i) service seems very poor and the failure mode you describe doesn't give me any clues despite 40+ years of service experience.
Ours is still 100% but I now suspect our trouble will come.

SOURCE: my olevia tv is not sensing the hdmi input right away.

HDMI has to be able to communicate with each other. In most cases the HDMI issue is with the device connected to the TV and not the TV itself. If you did firmware upgraded on the TV then the issue is with the laptop. Try the laptop on anther brand of TV and see what happens.

SOURCE: my TV says NO SIGNAL on tuner...

yes, you may be lucky to just to burnt one of the source/input mode try switching them.
for example use a video cable instead a coax if you still dont get a signal that means the picture uotput board is damage by the storm.

SOURCE: TV SCREEN GOES BLANK

Just posting what worked for me:

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

How do i find the hdmi source for virginmedia connection


When you change to the HDMI input for Virgin the TV will normally display the signal resolution and refresh rate for that source.

Some TVs will display the TV input name and source signal resolution and refresh rate when you press "i" (for info) on the TV remote.

Is that what you mean?

My sony kdl-46v3000 standby light blinks 5 times tv wont turn on


The TV enters standby mode when there is no signal for 30 seconds. https://docs.sony.com/release/KDL46V3000.pdf
I searched standby using Ctrl+F and found this information. It seems you should be able to bring it out of standby using the power button on the remote. You want to make sure there is an input connected and if it is connected to a PC that the PC isn't telling the TV to go into standby.
Try pressing the input button and changing inputs once you press the power button and the Standby is flashing.
If this doesn't work you may need to contact Sony Support.

Insignia 37" goes into standby mode


I am experimenting with Insignia's and there is a feature whereby if a signal is not detected the TV will switch to standby mode (in about 10 - 15 minutes). It's documented as a tiny "note" in the manual under "Understanding the basics - Turning TV on or off"

I don't know if the TV resumes when the signal is restored or if you need to power on manually.

You are probably experiencing a glitch with the signal or the TV thinking the signal is not there. Are you watching a clear picture when this happens? I would first check to see if the signal is too weak (like using a signal booster). If that is not the case, it's probably the TV acting up.

I hope this helps.

Is this

While trying to change channels, my t.v. displayed ''no signal'' and then shut itself off. Now, when I turn it on, it says no signal and turns itself off after a few seconds.


Turn the television on and as soon as the screen turns on repeatily press the input button or change the input to whatever input you are using from a source device. As long as you change it to anything other than RGB.

Your television is essentially a big computer monitor with multiple inputs and a tuner. When using your computer and shutting it down the monitor will go in a power save mode. You don't need to shut off your monitor due to this power saving mode. When you power up your computer your monitor automatically turn on.

With the VIZIO and the RGB (computer) input the television will act just like a computer monitor. When you have a computer connected it will power down automatically when you shut off your computer. When you turn your computer on the VIZIO will automatically come out of standby mode. This is through RGB only.

This is normal operation for the VIZIO but can see confusing when nothing is connected to the RGB input. If you change your television input to RGB it will sense no signal on the input and will go into standby mode after about 5 - 10 seconds. If you were to send a signal to the television through RGB it would automatically kick on.

Magnavox 15mf605t/17 15'' LCD HDTV won't turn on


Have similar TV. If it is set to the PC source, it goes into standby when there is no signal, like a regular monitor. Even though the monitor is in standby, you can still press the Source button to change to, say, HD input, and will use the familiar on/off action when pressing Power on the remote.

A little weird, but I've gotten very used to it.

Panasonic th-42px60u plasma tv not turning on


Power LED on front panel blinks several times, there is a delay, then repeats. After fiddling and fuming (mostly fuming) I found that changing the input signal source allowed the TV to be turned on. When I changed the input signal source back everything was ok.

In other words...

My TV is connected to my PC's video card via an HDMI connector. My card has 2 HDMI connectors. I moved the connector (the part that comes from my computer) from one HDMI out to the other. The screen powered up. When I changed the connector back to the original HDMI out I got my display back.

So yeah, try changing your input signal source. If you're using cable try switching to your Xbox/PS3/whatever, or vice versa. If you only have one possible signal source then I have no clue.

It's almost like the TV doesn't get any signal from the current cable then goes into sleep mode until it gets another signal. My problem had to do with me changing a bunch of sleep/timeout/screensaver settings on my TV/comp.

Hope this helps someone.

Screen says attention no signal


Your TV is probably on the PC mode and you are not using it as a PC monitor.

You need to change the source by pressing the TV/Video button on the remote control or the SOURCE button on the TV itself. You may also just press the channel up or down buttons. Do this before the TV goes to standby mode (amber light) or while it shows the message: ATTENTION NO SIGNAL.

If it does not work, reboot the TV first and do this again.
