Hi all, I have a 3 year old (2017) QLED70 model TV and about 6 months ago I started having issues with the red standby light staying on. I have followed all the tips and tricks of unplugging everything and holding the power button for 30 seconds and plugging back in only the TV; but nothing has worked. I even took the TV down off the wall 4 times now (which is not easy to to with a delicate 100 lb TV)! I've taken the back cover off and checked all the connections and checked the main boards and the power board; and they are all good: this also proved that the TV has and is getting power. The last time the red light went out, I got a little frustrated and punched the sensor where light was, and it came back on... not the ideal fix i was looking for but it got my TV to turn on again. This narrows my problem down to the standby sensor (either being a bad sensor, or having a bad connection, or having a bad circuit to one of the main boards). Can anyone help me troubleshoot this items and tell me what to do or where I can get a new standby sensor for this model TV? I really don't want to give up on this because I feel it is still a good TV.
