Narrative:

During climb out from bdl, the captain's radar altimeter flagged and the TCASII and GPWS subsequently annunciated 'fail.' the problem continued throughout the climb to FL350 whereupon I had time to ask a flight attendant to do a passenger electronic device walk. She discovered that a sony video walkman was in use in seat xx. After the sony was shut off, the problems cleared up. The item was a sony gva-500 video walkman.
