Check the color wheel and any fans running on the unit. The color wheels make a high pitch whin right before they quit as well as the cooling fans.

Loud squeaking coming from left rear 98 Ford explorer

A squeek would indicate a sound that is not always present. A squeel would indicate a constant high pitch whine. If it is a squeek you need to check shocks and grommets. If it is a squeel you need to check the brake system and the bearings

High pitched whine that overpowers the sound, CAN NOT get whine to stop no matter how the settings are changed

Most likely there is a transformer or a coil squeeling at the power supply. A repair shop should be able to handle it. Not to expensive.
