Remote sensor on the tv is not working.Have seen solutions on line that say put headphone jack into the "remote input" or "wired input" port.The 47LS4500 does not have this port. What is the solution?

use a phone camera and look at the front emitter LED the camera will show the invisible output as white light, if you indeed have output showing you can be reasonably sure the remote is working, here is a link for IR sensors on the plus side they all plug into the set with no soldering and just one screw.

Red light blinks 3 times then power goes out

That is most likely a bad diode in the power supply. It will require repair but it should be reasonable. There are youtube videos showing the repair if you are handy.

Im not 100% that this is the cause, but it seems like it
