We have training room with 3 TVs (tv left, right, confi_monitor) - all functions are working to all three TVS LIKE i can route AirMedia, local inroom Pc and hdmi wall plate.
Issue is when I press power button from touch panel, only two TVs respond and screens goes blank but one of tv (tv_left) is not picking up this power command and stays powered ON
ALL 3 TVs are using LAN connection and no rs232 and I can see all IPS and I can ping from laptop and text console success
I did find when I run Netstat -a from console, the tv not powering off, the IP is not listed.
I already rebooted all devices and made no difference.
It was working all last month and issue started yesterday.
Any what maybe the fix or where to look for??
NEC TVs connected using LAN, crestron room controller behind each tv, dmps processor, amp, Shurep300, etc…
I ran simpl debugger too but it seems to respond showing display_left 0-1 or it says command sent,
Not sure if need to completely unplug power cable from tv and wait 10 minutes??
I do compare all settings as well and it looks same on all 3 TVs and cec are off.
