Default Re: Alpine 7148L Car Stereo digital Tuning Fault

Having rechecked around the 4.5MHz Crystal, I decided to replace the two 22pf capacitors associated with it, plus a decoupling capacitor on an adjacent line. Hey Presto! The radio now works fine on all 3 wavebands, although there are intermittent problems with the 'Tact' switches used for station selection, etc. Changing them is gonna be a fiddly job, but one that must be done for the sake of reliability. I should, however, have checked those 22pfs sooner. Only being repairing radios for 37 years, that's all!!!
