In my family room, I have the AT&T DVR, a HDMI switch, and a 50" plasma TV. It has worked like that for over 3 years.
Today it stopped working. I tried two TVs, no help, I changed the HDMI switch, no help. I changed HDMI cables, no help.
I switched STBs with another room, no help.
So, with the STB and TV hooked to the HDMI switch, it does't work. With the TV hooked DIRECTLY to the STB, it works.
It's not the HDMI switch, because I tried two of them, and the playstation 3 works fine to the TV (through the switch).
BUT!!! this worked for 3 years and stopped working today.
I called Customer Services to see if there was a software update to my STBs today, but they don't know. Utimately after
a 30 minute discussion, they told me the system was working find, and they could dispatch a technician - which I could
potentially pay for.
SO. How can I find out if the software on my STBs was updated today. That would almost eliminate or confirm that
that is the source of the problem.
Also, does anyone have any experience with an HDMI switch?

I'm not aware of any firmware updates currently being pushed to the U-verse receivers. Also, firmware updates typically occur during the night on a week day and not during the day on a weekend.
Which U-verse receivers do you have?

The model number is underneath the power button on bottom-left side. For instance, VIP1200, VIP 1216, VIP1225, VIP2250.. etc.
Based on previous experience, please don't agree to a dispatch if you have a setup of anything other than a direct cable (be it hdmi/component/coax etc) plugged from the TV to the STB. I'd agree with the customer service rep that validated everything is fine with UV system.. it's correct. Possibly, it could be a voltage discrepancy. A small short in resistance between the switch and STB (based on HDMI adapter) could be the root of an issue.
If you can connect directly and cannot connect with a switch, I can understand it sounds puzzling, but a technician will and should not troubleshoot a non-working system due to 3rd party equipment in between the intended use. The only troubleshooting option I would inquire about is a STB swap.
