If this is true on all right channel inputs and not just one you tried , then id look at your effects loop send jack , there is a tiny switch inside it that must reconnect the right side send back over too main right channel fader in the older units there was a switch on back that did this but in later units this function was done with a micro switch inside jack
Testimonial: "Thank you so much for your help, but I am not a professional, so I can't follow what you suggested, such as what is "Effect loop send jack" and "right channel fader" etc. Please forgive my ignorance and give one more your kind advice. James P.S. Do you think I can get the schematic diagram from somewhere?"
sure those are available if you look on internet for them , just search your model and mfg name , but im gonna be honest with you if your not sure what the names of items (that I used) are on your board then im gonna say the schematic is not gonna help U too much , by your description of the problem I was under the impression you were partially knowledgeable of these and was looking for a direction to troubleshoot as I was a studio/mobile sound engineer for 20+ years so im pretty knowledgeable in these , in your case Im gonna suggest you seek a professionals help in fixing this , as the cause of your problem is probably not something just everyone can do
if you decide to still try I can provide technical names/explains of parts and pieces inside it

Place your mixer in a location that will allow you to hear the sound coming from the speakers clearly. The best placement is opposite the speakers, centered between the left and right pair. Connect the power supply to your mixer.
Connect the female end of an XLR cable to a microphone. Run the other end of the cable to your mixing board. Plug the male end into the "Mic" port of an open channel. These channels provide the preamps that will shape the sound characteristics of the microphone signal, processing them for output. Repeat the process for each microphone in your rig
Connect one end of a balanced 1/4-inch cable to the left channel jack labeled "L" found on the "Main Out" panel. Connect another cable to the right channel jack with the "R" label. Connect the opposite end of each cable to the matching left and right inputs on you amplifier.
Power on your mixer and amplifier. Test each microphone connected to the mixer for output.
Adjust the volume of each microphone channel to create a balanced mix. Use the "EQ" knobs to shape the tone and cut out frequencies that are causing squeal and feedback.
