JVC BR822 525 cannot be put into tape?
 

JVC BR822 525 cannot be put into tape. There was a recent problem with my JVC822 and JVC 525. Its door put the tape in the doorway, the door could not be opened, the heads would spin for a moment after plugging in and stop. The panel LED display is all 00000 Occasional failure code 04. I consult Chinese library data and show that the pole may be a serious fault or the loaded pole needs to be adjusted. Who has experience?
