| Sharp | 51DS02H CA10 | When replacing EEPROM | switch set on, after 10 sec delay whilst micro writes data, tune all the channels & select weakest then sw off tv. To enter service mode hold Ch+ & Vol- on front panel while switching mains on. Set comes on in service mode on weakest chan, using ch+/- on R/C choose "AGC take over" in menu & press STANDBY, set will adjust AGC automatically.
Now correct geometry if reqd.& press STANDBY to memorize. To exit service mode simply switch off. | plamensl | 14-09-2004 |
