    Well I have my S3 on its own UPS and I got home tonight and turned on the TV and got the "green screen" frozen TiVo again. I suspect it must be seeing something on the HDMI cable that locks it up on occation. The frustrating thing is that it is not consistent. Now my TiVo is stuck in a reboot loop (it reboots comes up for a few minutes then reboots itself). This is really getting annoying.

    Yikes thats no good. I agree the most aggrivating thing about this issue is the randomness of it. Everytime I turn my TV on I cross my fingers and just hope. Ican only imagine that unplugging/plugging the unit in everyother day must not be good for the hard drive.

    I will try to measure the components, after i find a meter.

    I've had the problems with the S3 and my SONY RP LCD. SEE http://www.tivocommunity.com/tivo-vb/showthread.php?t=318447 (originally thought it was Ethernet related per see since it only occured when PHY Enet connection was used)

    So I did find out what is causing the problem. Turns out that my old STB from comcast had a "floating ground" that showed itself when powering up the Sony. I did test with and without HDMI via 2 S3's with the same repeatable issue. What's bizarre is if I use the USB Ethernet, the problem never appears...it only happens when the phy Ethernet port is used.. If I removed the old comcast STB (goes to S2) (ie take off the splitter), the problem goes away....reconnect..BAM.. I suspect the incoming CATV connections into the cable card slots are not grounded / shielded enough to prevent this. I did connect the cable from Comcast w/o splitter into the S3 and HDMI/Component to the Sony with no problems at all...

    Again, USB Ethernet instead of PHY Enet does not show symptoms.. I guess that is what we get for being early adopters.. Tivo support after the 2nd box was useless...

    PS I have been freeze free since November!!!

    this sounds very promising, sorry to sound ignorant but is PHY Enet the same as ethernet cable/port? so you're saying that using wireless usb ethernet connection is what solved it?
    thanks.

    Pashasurf> Yes, he is referring to the actual Ethernet port on the S3. I am also using that port. The problem for me is that this doesn't happen consistently. If it does for you, unplug the ethernet cable for a few days (or at least have it unplugged when your turn on your TV) to see if it fixes it. A friend of mine with the exact same TV (Sony SXRD R60XBR1) who also has a Series 3 but uses the TiVO Wireless adapter hasn't had his S3 freeze yet.

    I will also be sure my Ethernet cable is unplugged when I turn on my TV (I might even get the TiVo Wireless adapter).

    Although it will be a bummer if this is true, it is far better than having something wrong with my TV. At least there is a workaround.

    Is there a way to add a ground to the Series 3? Why wouldn't they have one in the first place?

    The S3 doesn't need a ground because the case isn't made of metal so there isn't a shock hazard. Also the S3 should already be grounded through either it's connection to the TV (if there is any other grounded device hooked up to the TV) or through the coax cable connection for cable.

    You can forceably ground the S3 by running the cable (or antenna) coax cable through a grounded coax surge protector.

    Well in my case NONE of my components have a 3 prong plug (with a ground) in them. This includes the HDTV, Receiver, TiVo S3, XBOX 360 and Oppo DVD Player. Isn't that a problem?

    My 2 UPS's I use are grounded, but since none of the devices has a electrical plug with a ground that probably doesn't help any.

    Do you think buying a surge suppressor that has coaxial and Ethernet connections would fix this as well? Would that ground things properly?

    Maybe something like this?

    I thought the same thing, and tried a APC surge suppressor with Cable connections. No luck, still had the same issues.

    On the PHY question above. PHY as in physical ethernet, ie using the built in ethernet port on the S3. Using the USB port, you can use the wireless type or a usb wired ethernet dongle as well ( I am using a Linksys USB to Enet connector, just like I do on the S2)..

    thanks again sjxmang. i unplugged my ethernet cable yesterday and have had 4 power ups with no freeze! ordered a usb to ethernet adapter today.
    I would be so stoked if this was finally THE fix.
    Aloha!

    If that is the fix, that definitely sounds like a software glitch with the S3 since the voltage going across the Ethernet cable is very small and should have absolutely nothing to do with powering on the TV.

    The only way this could be a hardware problem is if they connected the component/hdmi port somehow to the ethernet port but I have no idea why they would do this as there is no ground in an ethernet cable. If this is what they did it is definitely a manufacturing defect.

    I did find a Ethernet Surge Protector. I'm not sure if it would help or not.

    My guess , if you notice the HDMI and Ethernet Ports are near each other, is that their might be extra solder or connection issue on the motherboard, but I am not about to go venturing around to find the cause :) My guess is the root cause is when the ethernet port is engerized, ie connected, their is a fault somewhere on the motherboard that you only run into if you have a power/ground float/etc. Tivo , hope you read this thread and fix the issue..

    FWIW, I did connect the S3 to a separate house circuit, a separate UPS and connect the Sony to a separate house circuit and UPS as well....if the physical ethernet port was used, I would get freeze...USB works fine!

    You know what you guys might try... You could put in a "ground breaker" on the coax lines coming in from your cable company. It can't hurt and it might help. My TV had horizontal lines rolling up and down the screen before I put the ground breaker on and now it's perfect. Anyway, you might give it a try. They are available at most places that sell TV stuff. www.hometechsolutions.com is where I got mine.

    "I've seen some weird ground-loop problems with HT setups that were traceable back to the cable system."

    I agree with BAREYB. A cable ground isolator can fix the strangest problems. Cable systems have been known to be the source of many "power" problems, 60Hz hum, horizontal lines on TVs, etc.

    Before you buy a cable ground isolator/breaker, you could simply disconnect the S3 from the cable system and see if the problem goes away. If the problem stops with the cable input disconnected, a cable ground breaker would likely work in this situation.

    May I ask what USB to Ethernet device you (and others) are using, as in brand, model number, (and version number, since the Tivo models seem to be sensitive to this) ?

    I am using the direct Ethernet connection. I connected my S3 to a UPS by itself almost a month ago, and has been running great since, but now I wonder if I have been really close to getting a freeze.

    Lastly, for those who are still experiencing freezes and crashes, are these on S3 boxes that have the 8.0.1 rev C update? This has not been discussed much in this thread.

    If things are running great why mess with it? I wouldn't change anything unless it actually freezes.

    I think everyone should have 8.0.1C by now. My S3 downloaded it the day after I bought it.

    BTW - The S3 doesn't seem as stable as the S2 as 100% positive that it had reboot itself when I'm not around (I'm about 99% positive it rebooted this morning a little after 10:30 AM). Fortunately it doesn't seem to reboot that often, but my S2 very rarely reboots (every few months if that). I've had my S3 for about a month and I'm pretty sure it's spontaneously rebooted at least 2 times (software installs excluded).

    I have been experiencing the freezes (the ones when I turn on my TV) on occation (not consistantly like others have). I have been running 8.0.1c since the day I got it (over a month ago) (I forced it to update soon after the initial setup).

    Are people WITHOUT an Ethernet connection experiencing problems? If not, then we might be onto something...

    It has worked for at least 2 people in this thread apparently and I know of at least 2 others who have never used the Ethernet port (they use wireless) that never have had this issue. This includes a friend of mine with the exact same TV, he bought the S3 the same time as me and uses the same cable company, but uses the TiVo wireless adapter.

    Unfortunately, in my case, my S3 (which is connected via the Ethernet port) only has frozen (green screened) 2 or 3 times when I turned on my TV since I got the S3 a month ago. I ordered a USB to Ethernet adapter to see if that helps but I guess if the S3 doesn't die when I turn on my TV in a few months that might have been the issue, although by then I would hope newer software (8.1?) would be out by then and who knows if that would have a fix (assuming it could be fixed with software). For now I am leaving the Ethernet unplugged and then on occasion I will plug it in (after the TV is on) and then force an update until my USB to Ethernet adapter arrives.

    USB200M from Linksys. http://www.amazon.com/Linksys-USB200M-EtherFast-Network-Adapter/dp/B000085ZKV


    From the thread above about disconnecting the S3 to test ground loop.. yes, doing that REMOVES the problem :)
