Appeared before searching, abnormal sound fault could not be locked program. AFT and image after intermediate frequency coil is changed after everything is back to normal (intermediate frequency IC TA8611AN). But to turn it off after a few hours, boot, image sound distortion after 10 seconds, a LO hop luo and noise, preheat before 30 minutes audio returned to normal.
