I just about checked all components in the power supply and even changed the regulator Ic but still I get excessive primary voltages, ie; B+ 200 volts, Cr4118 around 22 volts. Power supply will shut down within 5 seconds after plugged in because of overvoltage. I monitored these voltages when plug was engaged before shutdown. Any tips for this symptom, Thanks Neil TV Doctors Monroe,Wa ***************************************************************************** The Tech Address Book: http://www.tech-assist.org/secure/tip/contact.html Add a Repair Tip Here, or Change/Remove your Email Address: http://www.tech-assist.org/secure/tip/main.html Lost Password: http://www.tech-assist.org and select "Lost your Login Info?".
