Welcome. I am Mike, an experienced field technician. We are now connected together on this convenient website where I am able to help you. To get started, I need to know you can see this message and are able to reply to me here...

-Is the tv turning on? Has picture/sound?

-Is the tv responding to the original LG remote? menu, volume, etc?

please clarify "I've replaced some stuff"

Expert:  Mike G. replied 4 months ago.

Not sure why you can't reply to me....

Look in the HOME/MENU > LOCK > KEY LOCK > select OFF.

If that doesn't help then hardware disconnect / failure of the input board part number EBR72671401.

Before you go please take a moment to submit at least a 3 star rating at the top of this page. Then if you still need help you can reply back and I will be happy to assist you further.

Hi, I'm Carl. It looks like Mike opted out from this question. I own and operate a Electronics Repair Store and repair a good 10+ TVs a week and have seen just about everything. When I read the title of your issue I knew I had to chime in because I literally JUST fixed an issue exactly like this where the customer's Touch function quit then shortly after his Main Board died. I had to replace both the Main Board and the Touch IR Sensor. I found a little bit of corrosion on the Touch Sensor that most likely shorted the IC Chip then the Main Board. I've located a replacement Touch Sensor for you here:

Replace that sensor and your touch function should immediately be restored! If you need any help over the phone, I am also available Mon-Fri: 10-6 at my store. :)
