Hello, I am having trouble with my HDMI ports on my LN52A750R1F TV. All 4 were working beautifully until last night. We did have a power outage and when the power came back, none of the HDMI ports are now working. 2 are connected to XBOX units (Series X and 360), one to Chromecast and one to a Cable box. The ones on XBOX does show up in white font on the Source list, but it will just say "searching for signal". The 2 that are connected to Chromecast and cable box, just show up as grey font on the Source list. I have tried all of the following to no avail: Turn off EVERYTHING. Unplug TV and all HDMI devices. Wait 10 minutes, then plug them back in one at the time Click Refresh on the Source list Update to the latest available firmware via USB Plug the HDMI ports in different order I have not tried new HDMI cables, but it seems extremely unlikely that all 4 devices and/or their cables would be faulty. Any tips you might lend would be much appreciated. Thank you!
