Control panel & lights not working

Any help would be appreciated.

The control panel led lights and light bulbs are not working. Light bulbs in freezer are not working either. At first I thought light bulbs were out so I changed them and they still didn’t work. Then I noticed the control panel is out also.

The refrigerator makes 3 beeps also every few minutes.

Refrigerator is cooling and freezer is working fine also.

Thanks in advance for any help.
