Seems That The De-Gaussing Circuit Is Drawing More Than The Circuit Was
Designed To Do.
Main 4 Amp Fuse Blows At Turn On, Disconnecting The De Gaussing Coil
Eliminates The Fuse From Blowing And The Set Will Operate Normally.
Part 3523 Which Is A Dual Thermister Assbly Is Bad, Part # 2322-662-96753.
Part Is Already Not Available.
Philips Fix Is To Remove 3523 And Install Thermister Part # 2122-663-00019
In Empty Location 3507.
At This Time That Part Out Of Stock.
The L01 Chassis Uses
Clue If Degaussing Coil Is Unplugged Fuse Blows Will Stop.
Cause: Current Parameters Of Degauss Resistor And Degauss Coil
Resolution: Remove Degauss Resistor 3523 (White Rectangle) And Replace
Using Location 3507 With Service Code 2122 663 00019, A 3 Ohm Ptc
Resistor. Give Close Attention To The Marking On The Cba For 3507.
Applies To:
26pw6341/37, 27ms6341/37, 27pt5441/37, 27pt6441/37, 27pt6442/37,
30pw6341/37, 32ms6341/37, 32pt5441/37, 32pt6441/37, 32pt6442/37, L04.1u Aa
Symptom: After Replacing Degauss Thermistor (Ptc) 3523 With 3507 As Part
Number 212266300019 , The Fuse 1500 Continues To Open.
Cause: The Wrong Fuse Is Being Used.
Resolution: Use Only Fuse Part Number 242208610914. This Is A Special Time
Lag Fuse And Is A Safety Part.
Applies To:
25pt6341/85, 26pw6341/37, 27ms6341/37, 27pt5441/37, 27pt6441/37,
