*1. To measure with multimeter 500 type, the multiplying factor is [
×
10K], and the red test pen
connected to earth.
The resistance to earth of load of each power supply (with multimeter 500 type×1K/red test pen
connected to earth) are as follows:
VD621- =480Ω VD622- =500Ω VD623- =480Ω
VD624- =460Ω VD621- =480Ω
2. When the resistance of N601/PIN6 less than normal value, TV is in status of standby.
When the resistance of N601/PIN8 more than normal value, the switching power supply of TV
is in status of stop.
