You could try deleting the shard data on the pNode. You’ll need to know the ID of your pNode (it’s the text of QR code sticker on the bottom of the pNode) and the IP address of the pNode on your home network.
You would then edit the following URL where noted:
http://<YOUR NODE IP>:5000/restart-node?delete-data=1&qrcode=<QR CODE OF NODE>
This will remove all synced data and your pNode will sync from scratch. This is highly dependent on the speed of your internet link, but it will take a while for the pNode to fully sync the beacon chain. My pNode that is syncing from scratch right now, looks to complete the beacon sync in probably another 6 hours or so. Then it will need another 8? 9? 10? hours to (hopefully) fully sync the chain for shard 0 (that’s the shard it’s currently Pending for).
As I noted above, your pNode will be active in committee during Epochs 3476 and 3477. The current epoch is 3469. That’s a difference of 6 epochs or ~24 hours. That should be just enough time for your pNode to fully sync both the beacon chain and assigned shard chain if you delete the chain info right now. Even if it doesn’t fully sync by the time it enters committee, you’ll still be awarded block rewards. And if it completes the sync during the first epoch, you should see successful votes tallied in the second epoch.
