thanks to everybody who replies to this email, Bob,Jeff, and alll the others. This was the fix. The problem was a high pitch squeel. The power supply all the voltages were low exept the input pin 3 to ic803. The kicker was that the pin 3 was getting 36 volts ac at pin 3 found c805,and c806 leaky. and q802 was leaky e to c. c805 C806 ic903 q802 Thank you Pete Perdomo Tv Inc Since 1972 Miami.Fl ----- Original Message ----- From: "pete" <tvtech@xxxxxxxxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Thursday, December 09, 2004 7:23 AM Subject: [TechAssist] Fw: ct27g24a update high pitch squeel needs training manual > Perdomo Tv Inc Since 1972 > Miami.Fl > ----- Original Message ----- > From: pete > To: techassist@xxxxxxxxxxxxx > Sent: Wednesday, December 08, 2004 11:26 PM > Subject: ct27g24a update high pitch squeel needs training manual > > > Im still with this dog. all the pins exept pin 3 are low.
