Max here is some text I keep for the most common component failure in these sets with those problems. Some you may not have checked (some you already have). Replace CR4118, C4108, CR4402, C4402 & C4401 even if they check good. Also check CR4101, CR4606, CR4111, C4105, Q4101, CR4122, CR4123, R4150, R1928, R4114, C4705, C4115, CR4709, C4145, C414, CR3101, R4150, C4141, SCR501, CR4504, C4503, R3126, CR4303, CR4710, C4145, Q4105, R4102, C3124, R4704, R4713, Q3102, R4904, U4101, the yoke, pin of 12-13 of T4102 could be open, resolder L4803 & T4401, and possibly L4702, U4801, U1902, Q4302 check for shorts (pin 1-3) in U1901 If you are getting ~15v from the PS, IC3101 & Q4601 could be bad. If it's down below 15v, replace C4145. Could also be HV distribution block. -Clint God Bless Us All Clint Hamilton, Owner http://OrpheusComputing.com http://ComputerHardware-ConsumerElectronics.com sales@xxxxxxxxxxxxxxxxxxxx Fax: 209-882-9602 TechAssist Administration http://tech-assist.org techassist@xxxxxxxxxxxxx ----- Original Message ----- From: "Maxwell Bailes Jr." <bailes4@xxxxxxxxx> To: "techassit" <techassist@xxxxxxxxxxxxx> Sent: Thursday, November 29, 2001 10:35 PM Subject: [TechAssist] GE PTV Model# 46GW940 Chassis#PTK169PVA no standby voltage Hello, This PTV was going into shutdown,after about 10 miutes. I've changed R4110,Q4802, CR4402,CR4401,CR4118,C4402,C4401, C4104,C4102,C4145,U4101. I have 157V raw b+, 144 reg. b+,no standby voltage at all. Q4101 checks good. I lost standby voltage when I installed the wrong value cap. in c4401. install a .0128 1600V instead of .0162 1600V then Q4802 shorted all ways,Q4401 shorted all ways,CR4401 shorted. What I'm I missing? Any ideas? TIA Max ===== Max Bailes Bailes Electronics Rt.4 Box57-A Hurricane,WV. 25526 304-562-7167 ================================= Help make your TechAssist database better!
