Thank you for reporting this matter, let me help you on this situation.
Sometimes solid light means the source of the TV has changed, If the monitor has multiple video inputs, make sure you select the correct source.
Try a different video cable.
Check with the TV manufacturer for firmware updates.
If this still fails to boot the Intel® Compute stick, please test with BIOS recovery. See instructions for BIOS recovery at https://www.intel.com/content/www/us/en/support/articles/000005902/boards-and-kits/intel-compute-stick.html
You need the .Bio file to complete this task.
Please let me know your findings.
I have encountered this problem before. Here is what I will suggest:
1) If Stick is still under warranty, send back to Intel.
2) If warranty has expired, you might want to try to open the case, remove the battery and plug it back. I tired this on my stick and after doing that, I am able to boot again.
In my case, I disconnected the battery from the board, left it for maybe about 30 secs, powered up the stick and got it to work. Only when I managed to boot up, I shut in down again to reconnect the battery.
It looks like the state of the stick needed to be reset and removing the battery did it for me.
