При включении прибор выдает загрузочную надпись типа: "Roland Corp" и тд. и дальше не загружает пресеты, а сбрасывается, как будто перезагружается. Я такое видел на приборах с севшей батареей, но у роланда походу дела ее нет вообще. Данный глюк возник внезапно, никаким воздействиям прибор не подвергался. Сделать ресет не удается, как то перепрошить тоже не смог. Если у кого была такая проблема, напишите как Вы ее решили. Или подскажите с чем это может быть связано, глюк ОС или чтот с самим прибором?

Всмысле не удается? У меня кажица глючил, но ресет и все стало нормально.

1: Sequential test - factory test
2: LCD test
3: Switch test
4: DRAM test (self-test)
5: Flash test (self-test)
6: MIDI test (self-test)
7: Card test (self-test) - factory test
8: DSP test (self-test)
9: GA test (self-test)
10: I/O test (self-test)
11: Analog characteristics test
12: D I/O test (SRV-3030D only)

To start test sequence
Press NUMBER/ knob.
1: Sequential test - factory test (skip this option)
2: LCD test
All dots increase and then decrease contrast twice.
Visually check for contrast and missing dots.
3: Switch test
Operate the following controls and check the results
indicated on the LCD. The next test can be started when
the current control passes the test.
PARAM 1: Check to see that the reading changes for
0 to 100 to 0.
PARAM 2: Check to see that the reading changes for
0 to 100 to 0.
PARAM 3: Check to see that the reading changes for
0 to 100 to 0.
NUMBER/: Gradually turn the knob clockwise until three clicks
are felt and then counterclockwise for three clicks.
Verify the resulting changes.
While observing the LCD screen, turn on and off the
following switches one by one in the order given.
[ENTER] ® [BANK] ® [CATEGORY] ® [MEMORY] ®
[SYSTEM] ® [PREVIEW] ® [BYPASS] ® [UNIT A/B] ®
[CUSTOM] ® [EZ EDIT]
Depress and release the foot switch.
When all switches have passed the test, the test 4 will
automatically start. As the name implies, a self-test
requires only selecting and starting signal from NUMBER/
knob (simply press the knob).
