How do i take the button lock off my lg smartbtv with no remote
You can't. The television came with a remote because it needs one. Only basic functions with the buttons on the television, but you say they are locked anyway. Try disconnecting form the mains for an hour. If that doesn't work, Google
make model replacement remote
They are about $20 and an exact copy of the original. DON'T buy a universal remote. No one does that any more!
LG LED tv picture distortion
If hitting the corner fixes it the panel or screen is defective, in your case reverse the 2 flat ribbon cables and see if the issue goes to the other side, if not try a tcon board
Lg dp132h change the region code
Press setup on your remote and choose the lock symbol. Then go to area code and right click arrow on remote. Password should come up and put 0000 press ok. You will then be able to change the region for example Great Britain is GB. I've yet to test this out due the fact I don't have a corresponding DVD but if it works for you post your results. I'd love to be able to buy my favorite sci-fi shows no longer in US print.
Replacing LG tv backlight LED strips
Guess I'm a little confused at what your saying. LG sets have a male and female connector to hook the two strips together, once the strips are together they can be put in either direction as the plus and minus reverse on the ends, one side has the plus on the left the other on the right, no matter what direction you put them in the polarity will be right, make sure the connectors on the end are in correct as they can be hard to get together sometimes and check the end connector plugs, I've had them seem to be in but not all the way plugged in and the string didn't work...Good luck

LG TV repair please see details below
Unfortunately Kris the answer I give isn't going to be one you want to hear. I've had the exact thing happen a handful of times on set's I had apart to replace the backlights, I'm not totally sure what happens but I believe your screen (panel) was damaged when it's removed and replaced, could have been from static when handling it, I don't know exactly what happens to it but when it's put back together it does exactly what your set is doing when unhooking one of the ribbon cables going from the timing to panel boards. On one occasion I had a set the same model and series and replaced every board, connector ect and in the set I had the panel out of I didn't get a picture, put everything back in the set I had repaired and it worked again, only thing I didn't change was the panel. One thing you can try is check all the smd capacitors on the panel boards for shorts, if you find one shorted remove it, I've had issues with them being bad on a few sets and make the picture black. Sorry I don't have better news for you
Need to know how to fix my LG TV
It could be a bad power supply for your TV and the power supply is going bad. It would be more cheaper to buy a new TV than to try and repair the TV that you have is broken.
