OK, in that case push power button on TV front to get it turn On, does it work or power light turns to blue or red?
ah OK, does TV shut off in 15 seconds?
I understand, since TV shows 'no sync' message on screen that means it is On but missing video source signal fpr some reason like wrong video input selection or connected video device isn't On or not sending video output signal to TV or unplug connection cable between TV and video source/device etc.
- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?
If there is only cable box hooked to TV then please unplug cable box power cord from wall outlet for 5 minutes, check the connection cable(s) between TV and cable box to make sure it is plugged securely in cable box and TV. Replug cable box power cord in and give it some time to let it boot fully.
Now turn On the TV to see if it shows cable picture?
Please reply back with the result.
I understand, this TV has power saving feature, when it is On then TV will shut Off in 15 seconds if couldn't detect video signal from connected video source.
Can you please check what video input of TV is connected to cable box?
Is it HDMI-1 or HDMI-2 or any other video input?
Also, do you have DVD player to connect it to TV as a test?
OK, any other video device such as gaming console etc to try it?
We need TV to show picture to get it stay On then can go into menu to turn Off power saving mode.
Turn On TV and push INPUTS button on TV remote repeatedly to change video input source to different HDMI input.
Nice, let see if TV stays On with DVD playback, need to select correct video input of TV by pressing INPUTS button to get DVD player video signal.
OK, did it give chance to change the video input to get flash of DVD picture on screen?
Good, press Menu button on TV remote, does menu screen appear?
OK, so TV remote is also not working, please replace batteries of remote and try again.
On TV menu screen, go to Setup and set Automatic Power Saving option to No (off) to avoid this issue again.
Once done, change video input source to see if TV shows cable box picture?
This is odd, left/right button on TV remote should change its settings to On or Off.
is the TV remote working now?
No, please set the power saving mode to Off in menu - setup to keep the TV stay On.
