Question about Sony HT-7100DH System
Over a week or so, my HT7100DH system suddenly losses amplitude which I have to restore using the calibration cycle. This problem seems to be happening more frequently.
Have other owners had this issue?
I checked schematics of Amplifier unit (STR-K7100) in your Sony sound system HT-7100HD and found that all the data stored in EEPROM IC1131 in Digital board (right side of amplifier)
This IC1131 seems problem as it loses stored speaker level data and got reset for no reason.
You can reset Sound Field data by press and hold 2CH button and press Power button, you will see message "S.F CLR" in front display that shows sound field data is cleared.
Now store speaker level by calibration and check.
Let me know further query/ info by hit "add a comment" button.
