There is no phono plug input.
A magnetic cartridge produces an output of only a few millivolts and so not only should it be connected to an input with RIAA correction for the best sound, the input should provide full amplifier output from those few millivolts.
The sensitivity of a line in or auxilliary input can be anything from around 900 millivolts to 2.5 volts with 1 - 1.5 volts being typical and without that important RIAA correction. Read more about that here...

I suggest you invest in a suitable preamplifier.

Since the protection circuit trips after 4-5 songs at high volume from LPs, it may be that the infra-sonic rumble common to phonographic recordings is driving your amp stages much harder than it sounds like they are driving. You can check this with watt meters for your speaker outputs, or by filtering such extremely low frequencies on the input. If you have an equalizer--especially an old one--it may have an infrasonic filter, or just cut the very lowest frequency available on the equalizer after running your phono pre-amp into the EQ and the EQ into your VCR2 input. This setup will verify if your problem is the infrasonic rumble, but I wouldn't use it as the solution. There are very quiet infrasonic filters available that would work better for the long term. And if you just cut the lowest EQ frequency out, you'll miss some good bass.
SOURCE: TURNTABLE PROBLEM
You have a VERY nice turntable! TWO quick questions: 1) How do you define "minimal" volume? It is not NECESSARILY unusual that your turntable / receiver combination will have lower volume than your tuner, CD or DVD player. What happens when you CRANK IT UP?! Don't worry about the position of the volume control! 2)Are you changing the turntables output settings via the switch under the platter? Please post a reply and we'll go to the next step! Note: Ceramic cartridges are pretty much extinct. They were strictly low-end, low-cost, low-fidelity devices used in cheap audio systems of "yesteryear". Have you ever seen a BSR or Garrard turntable? Or your grandad's Magnavox Console Stereo? THAT'S where you'd find a ceramic cartridge!

is the wire loose on either end? sometimes the electrical plugs can cause noise due to resistance, so trying different outlets might help too

Turntable signal outputs are very, very low amplitude and either have to pass through a pre-amp before being connected to an amplifiers "ordinary" inputs (e.g. aux), or connect to an amplifier's specific turntable input in order to give the "normal" levels of volume.
This is because the cartridge (the bit that has the stylus or needle on it) can only generate very small amplitude signals.
As turntables are now outdated, a lot of amps no longer have a turntable input any more.
Unless you can also find a cheap pre-amp or an old amp with a turntable input, you may have wasted your money.
