Sharp Aquos IP control connection failure

I've run into a bit of a head-scratcher working with a Sharp Aquos 80" TV with IP Control. Despite having Quick-Start turned ON, when the TV is off, it immediately drops any IP connection after it connects. If the TV is already on, the IP connection makes and sticks OK. In fact, when the TV is off and I just do a soft reboot of the controller, the connection will stick. But if I hard-power the controller, and the TV is off, the IP connection just refuses to hold. The device comes online, and then immediately drops back offline again.

I'm kinda stumped. I've got a lot of other Sharp Aquos series (mostly 60" TV's) that connect and work fine whether powered off or on, hard or soft reboot on controller. But this 80" TV (and now I suspect another 90" is doing the same thing), have trouble keeping the IP connection.

Any ideas out there?

    Sounds like the ethernet port is turning off with the display. Have you tried adjusting the Sharp power saving features using the OSD? I forget what it is called, but this is a common problem with Sharps.

    IIRC you need to send the RSPW command to it while it's on to get it to answer while off. I think it's "'RSPW2 ',$0D" (three trailing spaces) for IP connectivity. It's been awhile since I did IP control on one of those though, so that might be off by a bit.

    AHA! Now I remember it at least used to work this way when running RS-232 control. This might help, although I'm pretty sure I never sent that command to the 60" TV's I've got working. I don't have it in my code anywhere. I'll definitely give that a try though.

    I definitely have the quick-start setting on.

    Thanks!

    Quick follow -up on the RSPW thing... I'm not even sending it a power-on or any other command, I'm just doing an IP_CLIENT_OPEN. The Data_Event{ Online:{ event triggers, then the Offline:{ event immediately triggers with an error=0. I was just sending it a power query, "'POWR? ',$0D" but the device drops right back offline whether or not I try to send it any command.

    It seems like the Quick-Start setting, just isn't actually setting.

    Gotta admit - the only IP control of TVs I do nowadays are with EXB-IRS4 :)

    I simply do not trust the TV manufacturers to stay long enough an a protocol to trust them.
