SonyAE1Blank screen, no tuning memory when heatedMemory chip IC003 (M58655P) used in AE1 chassis requires -30V on pin 2 to operate. If -30V is lost, no station memory - check L807 for o/c in LOP when warm. L807 used as voltage dropper to reduce volts derived from transformer & its inductance (10mH) is important. It should always be replaced with original part, otherwise damage will occur - part no 1-407-504-00.14-09-04
