SHARP	CMS-R260CD	Do not tune in radio am/fm	Microprocessor defect, which also does not send the information to the Open/Close of the CD	After replace IC 201 (front end) and IC203 (IF and MPX) and continue in the same, with the signs follower, I found FM stereo sound, the defect was in the micro, to get around the problem, I turned off the pin 5 In the CNP402 connector that goes to the panel, but the sound only appears when it placed the radio manually, to remove the Mute from the station out of tune and help the search, I turned off the Pin 2 from the Q251 transistor (RN2202). Now it has sound, but the tune will be manual. I took advantage and memorized all the radios to make life easier for the client who did not give up Radio FM.	Trendset
