I run a Tripp-lite HT1000LCD for maybe 10+ years? I have it plugged into a powerstrip and switch it and the powerstrip off when PJ is off. For one, just don't see the point in having AC to the PJ when not in use, as it isn't used every night, etc. Secondly, when there's AC to the UPS, it stays warm...sometimes pretty warm. This is obviously charging the battery or maintaining it, but heat shortens battery life, and the charging too. I've only replaced the battery once in 10 something years by having it powered down most of the time.
I've run my Mits HC3800 and now JVC RS57/X700 off it. Might have had my first PJ's, Optoma H30 and H31 on it too (can't remember!).
So it's a little inconvenient to turn the powerstrip and the UPS on whenever I wanna fire the PJ up, but keeping the UPS warm and cooking 99% of the time it's not needed seems inane.
This all worked seamlessly until recently when a hdmi handshake issue popped up about a year ago. I basically only view Spectrum HD/DVR and Blu Rays, but when the PJ/UPS/powerstrip is OFF, switching between anything not hdmi 'locked', it will no longer lock. Say I'm watching Spectrum on PJ, then power down to watch the flatpanel....that's fine. But if I'm watching blu ray, then power down PJ and switch to cable/flatscreen, the hdmi will not handshake. So I make the switch before I power down the PJ.
But, if PJ is already powered down (and UPS is off) and I make a switch on my Yammy (say cable to radio and back), the only way I can get hdmi locked is to turn on the UPS for a couple of seconds, then off. I will get the handshake (I don't have to power up the PJ, just the UPS).
Now this has become a pain, as I do switch from cable to radio quite a bit, and every time I'd have to power up the UPS for a few seconds to get a lock.
Strangely NOTHING has changed in my setup. I'm guessing it might be a Spectrum/cable anti-pirate FW/SW update to my DVR (sent over cable via Spectrum of course) that caused this. The obvious solution is to just keep the UPS powered up all the time, AC present at the PJ. But having the UPS cooking 24/7 just for this issue is also inane IMO.
I haven't troubleshooted this yet (like unplugging the DVR from my Yammy to see if everything else handshakes), as it's a bit tough to get to the cables, but if it is indeed the cable box, I'm wondering if there's any hdmi solutions for this apparent hdmi issue the DVR isn't liking? Like some sort of electronic hdmi disconnect that would mimic as 'no cable plugged in' when the power is off? Because if I manually unplug the hdmi from the PJ, it also solves the hdmi handshake issues (cable and radio on flatscreen).
So, dependent on your cable/Sat, I’d check that your hdmi handshaking works ok with your hdmi cable plugged into your PJ, but your AC cable disconnected (no AC pwr at PJ). Unless you’re ok with your PJ UPS cooking all the time…
