Service Adjustments
1、
、 Please notice the following before Servicing
The main power is 90～260V/50/60Hz, Please be careful when you debug and
equip.
1-2、Don’t short any two soldering points, which should not be shorted and don’t
touch any components, which should not be touched.
1-3、Please disconnect the power plug from the wall outlet before servicing.
1-4、For safety reasons, all components equipped or replaced should be identical with
BOM.
1-5、Before alignment, ensure the TV set has been heated for at least 30 minutes and
degauss the CRT thoroughly with demagnetizer.
1-6、The data of EEPROM must be stored before the adjustment for main chassis.
