Hi. I'm receiving a 47" tomorrow, and decided to prepare for it by signing up and reading a few posts. Thanks for the pointers to CNet recommended "settings", and I shall watch closely for new posts about the "screws to tight?" backlight repair theory.
I don't know, because I don't yet have the TV -- but I wonder if some "frequent-resets-when-internet-is-connected" issues might be might be related to DHCP release-and-renew address updates from your home routers. This would apply to BOTH wired and wireless connections, so it would seem to be a possible match for the symptoms which have been described. If this is
the source of the problems, they could be avoided by eliminating "automatic" address assignment, or by reduced (greatly!) by lengthening the Release/Renew "time-to-live" period on the Router.
- - -SOME BACKGROUND:
"DHCP", Dynamic Host Control Protocol, is how the TV and other interenet devices (computers, web cameras which run INDEPENDENT of computers, files servers.... etc.) receive addresses from your router. Your Router sends 4 things:
(1) The address which "YOU" are now being assigned by "ME".
(2) The address from which you may request the address from names you don't know. (The is the "DNS Server Address")
(3) The address to which you send all data which isn't local. (This is the "Gateway")
(4) The "mask" of addresses which are NOT local.
In a "normal" home router setup, the Router itself is used by "downstream" devices (TV, computers, etc) as the Gateway AND the DNS Server. The address will usually be 192.168.0.1 (although some routers use 192.168.1.1), and some people have multiple, or different networks in their houses (I do - and I'll go there in a follow-up if you really
want to know about it.)
- - -HOWTO: FIXED ADDRESSING
This would completely eliminate the problem, but it takes more work. Login to your Router, and find the following information:
The router's address. Be careful: we don't want the address of your ISP/Cable/DSL/UVerse/DirectTV "upstream" address (assigned to your router by them, or by their modem) we want the address which the router uses within your house. It WILL
be "192.168.xx.1", unless you have messed with it in a really weird way.
The other thing you need to know is the router's range of DHCP addresses (The addresses which it could "hand out" as dynamic addresses). Most Routers are willing to assign about 40 addresses. Look for the first number in that range, and the last number in that range. These are numbers which you must AVOID USING as "fixed" addresses.
Now go into TV Internet setup, and switch the 4 variables (Address, DNS, NetMask, and Gateway) from "auto", [impossible to enter], "auto", "auto", "auto: as follows:Address Mode:
Manual. This eanbles the field where you enter an explicit address.Non-Auto Address:
A unique number, between 10 and 254, but NOT inside the range of numbers which the router will use for DHCP. For example: If your router is using 160 through 199 for DHCP "dynamic" addressing, you might choose to have your first "fixed address device" as 192.168.0.200.Network Mask:
Unless you have something really weird (as in: YOU are Time-Warner, or ATT, or Charter Cable), then set this as: 255.255.255.0Gateway:
Specify the Router address, (192.168.0.1 , or maybe 192.168.1.1)DNS Address:
Specify the Router itself as Primary (same address as "Gateway"), and specify Google DNS as secondary ("184.108.40.206").
Finally, create a little document on your PC, or paper in your file cabinet, with a picture of your home network -- showing all devices, wires, and wireless NICs, and show that you've used this address for the TV.
BTW, that took me 10x longer to write than it will take you to do the job.HOWTO: LENGTHEN THE RELEASE/RENEW TIME PERIOD:
This easier, but less likely to be effective: Log in to your Router. In the DHCP parameters section, look for something like "Client Lease Time". If the value is shorter than 1440 minutes, increase it to that figure. (1440 minutes = 24 hours.)
