Symptom: Dead set. Open AC line fuse, 1500. Replacement may blow again.
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
212266300019 or 212066100025, 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.

Subject: [TechAssist] Philips 27pt6441/37 Blows fuse
I have had two of these L04.1UAA chassis in this month with the 4amp SB fue
blown. The deguase circuit draws in excess of 5 amps AC momentarily at start
up. I have replaced the fuse and they play fine. Has anyone seen this
failure?
Thank You,
