LG TV "INVALID FORMAT"

by Blazin65 / July 19, 2009 1:04 AM PDT

I have a LG 37 inch tv that I'm loosing my patience on. The problem is, almost every other day, I get an error message that says invalid format. The only way I can get the TV to come on is to turn it on and off @ 5 times. I have already replaced the HDMI cable, and it was better for a while, but now the problem has come back. I've called DirecTV, and of course, they say it's not them. Has anyone had this problem?

Direct TV says this:::::

Just a note to anyone that might have read this. According to DirecTV, the problem is in a Native Resolution setting. Long story short, with the Direct TV remote, go to menu/set-up/system set-up/HDTV/ and then turn Native Resolution "Off". Supposedly my TV is capable of 1080p, but the satellite reciever is only capable of 1080i. Somehow the software of the LG TV was conflicting with the Satellite reciever. I finally got LG on the phone and they said the same thing. Maybe this fixed it.

LG 50 inch palsma TV. "Invalid format" on only bluray.

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!

To the returns counter. Product that fails to perform deserves to be returned for exchange or refund.

"invalid Format error" on LG plasma TV only using Bluray

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.

By the way, LG says no firmware upgrades are available now or in the works...

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.

HDMI PC to TV showing "invalid format"

In reply to: LG TV "INVALID FORMAT"

after days of trying to configure my laptop and my tv I decided to take a lamp and look very carefully the HDMI port on my laptop and I found out that one of the little pins inside the HDMI connector was all the way in so it was not doing any contact with the HDMI cable, what I did was I opened my laptop and found the HDMI port and with a little screw driver I pushed the little pin out and it works!, but I STRONGLY RECOMMEND NOT TO DO THAT, at least that you know what you're doing, otherwise you can damage your laptop. This was my experience and it works for me.

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.

Hi,

Just go to DVD player menu and set picture resolution to 1080 i instead of 1080 p (or reverse depending of "TV DVD combination")

It will work

Unplug the TV for a Few!!!

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.

Most of the time you have set your OS screen resolution too high.

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.

Invalid Format with LG TV and DVD Player: SOLVED!

I had the same problem tonight and solved it. I have a LG TV but also a LG DVD player. I went into the setup menu and while I was working through the type of connection it makes to the internet, it found a firmware upgrade for the DVD Player, not the TV! I let it apply the update and no more invalid formats. DVDs all play properly.
