Dear Jack,

how many boards have you tested? Have you tested to replace a TEA2096T from the board, which passed the test to a board, which hasn't passed the test? And vise versa? If yes, which board is now not passing the test? 

Please confirm the source of the TEA2096T components. Have you purchased all of them from one of our authorized distributors? Please state the name of the distributor.

With Best Regards,

Jozef

180 pieces were tested, of which 29 had abnormal no-load power. The supply agent is DIGIKEY。

Replace the TEA2096 on the board that passed the test with the board that failed the test, and the test result is still unqualified.

TEA2096 is abnormal. When replaced with a board that passed the test or failed the test, the test results are both abnormal.
