" check signal cable" message stays on the screen of HDTV

by bobby2501 / August 23, 2009 8:28 PM PDT

I have connected my laptop to my Samsung 32" HDTV( 5 series) via VGA cable. I am getting a perfect display of the computer on my HDTV. But there is this message "check signal cable" which stays in the middle of my TV display and does not go away.The message stays even though I am getting the display of my computer on my TV.

Is it because of the VGA cable I am using or is it because of my video card ( i am using nvidia 8600M GT and windows vista).

Is it possible for me to disable this message "check signal cable" on my TV.

Have you checked to make sure you have the latest driver? If it's a Sony or HP, you almost might consider updating the BIOS on the computer, which you can find on the manufacturer's site.

Samsung T220HD on HDMI cable shows CHECK SIGNAL
by keatssoder / July 24, 2010 3:24 AM PDT

I have a Gateway with the same problem when I use a HDMI cable. The monitor does dot sense to sleep when HDMI signal goes away. It is clearly a monitor not sensing problem. I wonder if add another monitor cable might shut the monitor down when the computer shuts down?

Same issue of mine fixed
by samkat11 / September 23, 2010 8:27 PM PDT

Hey Bobby,

Even I had the same issue when I was connecting my VAIO with HDTV (5 Series).

Hence, I tried the following options.
1) Looked for updated BIOS / display drivers - No Luck
2) Connected another laptop & PC - No Luck
3) Took my laptops to a Samsung showroom and tried connecting it there using their VGA cable - It worked.
4) Then i tried my VGA cable (assuming that my cable might be the root cause of the problem) & surprisingly it worked.
5) Connected in all possible series of LCD & LED TVs and all of them were just working fine.

Finally, under the assumption that may be I was not so lucky while buying the TV, I contacted the Service centre.

They told me that it's a very common problem in many Samsung LCD & LED TVs. He just replaced the connectivity board on my TV with a new one and now everything is working just fine.

Hence dude, If your warrenty period is still active then I would suggest you to try that option once as well. who knows it might work.

Good Luck.

My fix

I know this is really late, but I had a similar problem which I resolved by changing my primary display to a monitor (not my TV) or using the "Duplicate displays" mode. The problem for me was that the TV can not be the main monitor.
