CTC 169 Proj.
Set had shorted u4101, Q4101 and open 1.8 Ohm resistor in power supply.
Changing these and caps and diodes in this area returned standby to143 volts at cr4116. Changed cr4118, voltage at 13.6. When turned on, standby voltage will drop off. Horizontal output will start for about a second and shutdown. Have checked HOT and seems OK. Have remove lead wire to HV splitter with no difference. Secondaries off the flyback start but do not reach full voltage. Pins 4, 5, 7, and 9 are at ground . Is this normal? Any suggestions? |
