Adjustiing/mod'ing digital thermostat on LG window air conditioner

Don't assume this is an electronic problem. You haven't gathered all the data.

What is the entering air temperature to the coil? What is the discharge temperature? What is the delta T?

There are more measurements you should take but those two are the steps you can't skip.

Yeah, he will fly in and then have a parade to the house to pull the plug. Just ignore that carbon footprint...

They weren't really fish. Just scales falling off his private area because of all his fishy ideas.

IDK, but 65 is way to cold for me. I have the AC set at about 76. Sometimes a couple degrees lower temporarily if needed to get it to run enough to take the humidity out. Is it cycling at 65 or running constantly and unable to go any lower? Depending on the ambient conditions, maybe it just can't go any lower. And where are you measuring the temperature? It could be substantially lower at the AC compared to elsewhere in the room.

The problem here is that I bought this to cool a wine cellar. The ac unit is in a fake window between two parts of my basement. The wine cellar part is well insulated, but you can't get 60 F (the temperature I really desire) if the calibration on the thermistor is wrong. I am getting ready to use a fixed resistor along with a pot, and hope I get lucky.

IDK see why you'd need a resistor and a pot. And are you saying you're just going to use those or use them in conjunction with the thermistor? Without the thermistor it won't work. It would seem a pot and the thermistor would do to tweek it. Have you been able to measure the resistance of the thermistor, see what it is? Many of them are 10K ones, you can find them, 10 for $2 maybe on Ebay and there are curves online. Or if it's 10K, then a 1K pot in series should work to tweak it.
