Facing TV Problems? Ask a TV Technician.
Hi , I`m Jack Perhaps I can help you with this problem , let me know when you`re ready ?
Here are a few things to try and check ;
Does the cable box work if you connect it in the same port used by the PC ?
Does your PC see the tv as a second (or first ) monitor in the screen resolution menu ?
If using a laptop try to shutdown the lid and see if it comes up on the tv ?
Reboot the PC with the tv set to it and watch the screen and if a desktop pc , disconnect other monitors .
This tv has a RGB IN (PC) input , have you tried it ?
Sorry , got locked on another post while waiting for your reply
Can you confirm that the HDMI inputs are working (beside the laptop) ?
When you say that the laptop sees the tv , does it recognize it as LG and sets it to (recommended) resolution ?
Was anything changed lately in your video settings /drivers etc. ?
Can you restore the laptop prior to this when it was working ?
Yes but if some program changed things or your software got corrupted then a restore bring things back to what they were , computers are not impervious to software changes , they are the worse .
Never mind that for now anyway
You said you see the tv with the RGB cable , I was asking with the HDMI cable connected ??
You tried everything I was asking with the HDMI cable disconnected ??
I`m sorry but i will have to opt out now.
You don`t have to do anything , your question will be reposted for other techs. to see and jump in.
