In Reply to: LG TV "INVALID FORMAT" by Blazin65
We recently purchased an LG 46" HDTV to replace a failing Samsung. We really like the picture and overall performance, but after about a week of use we began to experience the "INVALID FORMAT" error when turning on the set. (The LG is connected to a TWC Scientific Atlanta 8300 via an HDMI cable. The SA 8300 is set to transmit 1080i, and that setting is "locked" in the SA 8300, so there should be no "hunting for best option" behavior on either end.)
At first we could remedy this problem by switching the LG's "source" from the HDMI to its' internal tuner ("TV") and then back to the SA 8300 HDMI. Then the "INVALID FORMAT" condition began to occur at random times during the day.
I finally decided to review every setting that I could find in the SA 8300 and the LG HDTV. I made no changes in the SA 8300, but - as an experiment - turned on the "Simplink" feature in the LG. (I had not turned that feature on during initial LG setup because (a) our SA 8300 is not a "Simplink" device, and (b) our Bluray player is an "Anynet+" device.)
Much to my surprise, since that change we have had no (none, zero) occurrences of the "INVALID FORMAT" error.
The only explanation that I can offer myself is that activating the "Simplink" feature enabled some additional signal-processing software that made the LG better at recognizing signal input over the HDMI link.
