LG forum: LG TV "INVALID FORMAT"

You see this issue to sometimes be a firmware update (sorry if I nod here and wonder why we accept that).

http://www.avforums.com/forums/lg-owners-forum/900234-37lg50-tv-lg-lht-854-dvd-invalid-format-error-tv-cant-use-hdmi-now.html may be a better forum since there is a LG presence.

And yes to your question. Hint: Go component on it.

I've got quality HDMI's v1.3, and keep getting the invalid format error. RARELY, it will work. I tried my Samsung and Magnavox Bluray players and done firmware upgrades on both. I've connected the Blurays directly to the TV (rather than thru the receiver) with the same results. Direct TV HD works just fine! Tried the different HDMI ports on back of LG as well. Component jacks didn't help any either. Both players work fine on other TVs. Help!

Despite that fact TV is reportedly 1080P according to my manual(LG 50P5D) and Direct TV works fine in 1080P resolution, LG online chat (got disconnected 3 times and took over an hour...) says it's only 720p WXGA. I hooked The Bluray to another TV, changed the resolution to 720 and wala. Bluray works, despite DTV still working on 1080P with native resolution. Not happy, but at least it works... I've had the TV over a year, so return not an option. Thanks.

Try every HDMI cable you have. One time this paid off.

Sorry to read you got stuck with the product. Those that had pre-HDMI are really smarting.

I fixed this problem by hooking my blu ray up via the RCA (red, yellow, white) cables and going into the the blu-ray's settings and changing the resolution to 740p. I then disconnected the RCA cables and connected the HDMI cable. That worked for me. I can't explain why 1080i doesn't work however.

Just got this answer from a helpful tech. Unplug the tv for a few, let it boot back up then try your hdmi inputs again. This resets the microprocessor.
