'MODE NOT SUPPORTED' message appears on my TV screen

There could be a few different issues that could cause the behavior you're describing. Here are a few possibilities:

HDMI connection issue: Make sure the HDMI cable is properly connected to both the TV and the laptop. If you're using a HDMI splitter or HDMI switch, make sure those are also properly connected.

HDMI port issue: If you've tried multiple HDMI cables and still have the issue, there could be an issue with the HDMI port on the TV or laptop. You could try a different HDMI port on the TV or laptop, or use a different device to see if the issue persists.

Display settings: Make sure the display settings on the laptop are set to display on the external monitor (the TV in this case). If the laptop is set to display on the built-in monitor, it may cause the display to flash on and off.

Hardware issue: If none of the above solutions help, there could be a hardware issue with the TV or laptop. It's possible that the display controller or other hardware component is faulty and causing the display to flash on and off. In this case, it may be necessary to have the device repaired or replaced.

I hope this helps! If you have any further questions, please don't hesitate to ask.

Here are a few ideas:

• The No Signal, No Source or No Input message will appear on your television screen when the television is not receiving a signal from your Digital Box. This is often a result of either the Digital Box being powered off, not being properly connected to the TV, or if the TV is set to the wrong input.
• Press the "TV/VCR" button on your remote control if you are experiencing no picture. This button will allow you to toggle between TV and VCR screens and may solve your display problem.
• Make sure your cable box is turned on.

DI cables have little end caps, make sure they are removed

solution to Both our problems is this, call Philips, "it just so happens that we have a rapid replacement program for this particular system"-"there seems to be an internal electrical problem", so I'm sending it back to them.......
