Hi Maryann, When the store you purchased the TV from tells you it is like a ROKU I am sure they only mean that it can provide streaming services in much the same way, the actual setup and day-to-day usage are going to be completely different.  How far have you got with setting up the TV, can you even watch programmes via your aerial/dish yet?

THE MODEL OF MY TV IS:   32LK540BPUA  EVERYTHING IS WRONG, I DON'T KNOW HOW TO SET IT UP, LIKE I SAID WHEN I GOT MY TV FOR CHRISTMAS I CALLED WHERE IT WAS BOUGHT AND THEY SAID IT WORKED LIKE A ROKU, I HAVE A ROKU AND BELIEVE ME IT CERTAINLY DON'T WORK LIKE A ROKU, I DIDN'T WANT TO TELL MY FAMILY TO SEND IT BACK, BUT I WOULD LOVE TO BE ABLE TO WATCH IT, AT THIS RATE NOT KNOWING WHAT TO DO TO MAKE IT DO ANYTHING I'M NEVER GOING TO BE ABLE TO WATCH IT.

@txydas Hi, thanks. I tried to find the item on ebay. But I realized that here, in IRAN, sanctioned by Ultimate Satan Administration (USA), it is a tedious task to buy using ebay or amazon or ... if not saying impossible, because a TV WiFi RF module may be used in nuclear warhead, according to them. LOL! anyway, per the experiences reported in this forum, I tried to see what the module is. At the first glance, and more and more scope, no obvious fault was detected. everything seemed to be OK. So I just disassembled the module and the ribbon cable at both the module's and mainboard's header. I experienced that the TV had little or no sense to magic control. So, the module was not a thing could be ignored. So I took some photos and reassembled them again after the only common remaining task, i.e. cleaning by a spray solvent. And now, it is for 3 days that the TV has operated flawlessly. Everything is OK; Magic control, WiFi, Screenshare, No message, No pause or delay in the stream display ... I wonder what the bug was and wonder whether it would be coming back? Who knows? It was recommended to me to substitute the TV to another model or brand. It is not my decision for now. So, It may be helpful if the users, who have replaced the module, say in please that if the same tasks were done before replacing?

I am not sure what you mean. My WiFi module worked fine and I never had a message on my tv screen about an unknown device until the latest software update.  I don’t take to blaming manufacturers lightly and never have done so before. I only came to this site about a month ago looking  guidance when I wasn’t finding  it on the lg support site.  The things that were suggested over there didn’t work and we were told they were working on a fix that didn’t come. Others with the problem tracked it to the WiFi module so I went there also. This is lg tv is a replacement for one that went bad while still under warranty. 

For the Free Movie internet channel, the movies you select as a on demand movie, how do you resume playback where I left off?

Excellent so users can definitely blame LG for the issues then, anyone else out there got information about their failed units?
