My LG 32LX1D TV has lost its on screen TV guide. I am just getting a black screen with a small video window in the corner. I am using a cable card with Cox cable. Yesterday I added an external antenna hoping over night it would pick up the over the air signal, but today is the same as yesterday. I have read about an update file for my TV but talking with LG yesterday, they say there is no updates for my model and are unaware of this issue. Cox cable came out yesterday and checked everything, they found no issues. Any ideas?

After purchasing a "service remote" and then buying a new "Main Board-Analog" which didn't fix the problem, I spoke with tech support who then emailed me an "EPK" file. Basically the computer board inside the television needed to be updated since this whole digital conversion is happening.. However this incident has given me tremendous knowledge of what to do and how to troubleshoot and how to reset my own TV with all the hidden menus that you never knew you had. Don't be tricked into buying a mainboard or even paying a diagnostic fee. If your TV GUIDE screen goes blank and all you see is a small channel preview screen in the top left corner, chances are all you need is the EPK file update. I received the update file in my email, I downloaded it to an SD card, inserted the SD card into my 32LX1D LG LCD TV and it did the rest. It was too easy. Most newer LG TV's are coming with a "SERVICE USB" so you can attach a "jumpdrive" or some other storage to it. These so called "Authorized Service Centers" are a hoax. WHen you bring your TV into them they charge you a "diagnostic fee" ranging from $50-$150 just to diagnose it, then they tell you that that can also be applied to the cost of the repair. All the service center does is call a special priviledged tech support 800# for LG to find out what to do. I've replaced and removed my own Main board. You gotta learn the game people, its all a big game to keep the revenue coming long after the sale of the TV. Which is why nowadays automobiles are manufactured with parts that were made to break intentionally to keep bringing you back.

the digital main board typically fixes this issue

Yeah I have the same model and there's no built in antenna. You have to use an external. I used to work for the geek squad in a Best Buy store and I can tell you from experience that that salesman may or may not have actually known that there's no antenna built in. It's not uncommon for them to tell small lies like that to get you more interested in the product. I witnessed it a million times before I finally quit because they wanted me to be the same way.

For all of you who have this problem, it started when TV GUIDE began to do their conversion to Digital. What you need is an "EPK" file update. I have that file and have no problem emailling it to anyone. I bought a service remote and changed my own main board which I have returned because I found the right solution. LG was no help at all. I am so pleased and happy that I can help anyone. Email me at [email protected] put "TV GUIDE" in the subject line and Ill forward you the file and what you need to do... within 4 minutes you will be back to normal.

The problem started with TV GUIDE messing with things while they are doing their digital conversion
