I am having problems with the monitor screen on my AVH-P7500 unit, it will strat to come out of the dash, then returns inside. If I hold up gently on the front of the monitor, it will continue to come out and raise, but not to its normal position. anyone have the same problems and know what a simple fix. The factory recommends sending it to a factory rep in Arlington, Tx. any help will be appreciated. Chales
