Ok, I uploaded a youtube video in the following link. https://youtu.be/Npw5flnQvqg
Thanks so much.

Sir, did you do self calibration after you replace the chip?
If not, please disconnect and probe and cable to the input connectors, power on and wait for 30 minites.
Now start self calibration.
After that, if the problem exists, please let me know.
