Jeff,
From Tech Repair CD:
NAP\TP3281 D7\No turn On\Flyback popped taking out Jungle IC and other stuff.
Many cases include loss of
H drive and others may have loss of video. There are several different
versions\of this chassis* so part
numbers may vary. These are the most common parts that die when the flyback
takes a dump... check them all
when replacing flyback (IHVT).\D7\see D7 Link in this NAP
table.\http://wa6ati.com/D7-DOC.pdf\\\\\\\
Magnavox\TP3281C101\Dead- indicator comes on clicks once\Good power supply
voltages including the 130v
supply\LED repeats a series of 4 short flashes and one long flash but the set
is otherwise
dead\32D700\When servicing either a D7 or G7 chassis the flybacks are a common
failure\There are several
components that also need to be checked as they can be damaged by the defective
flyback\Ref# 3610 22K
resistor part# 483511657706*Ref# 3331 47K resistor (SMD) part#
483511137445\Ref# 6328 Diode (SMD) part#
483513037095*Ref# 7325 Transistor (SMD) part# 532213060508\Ref# 7150 Signal IC
- Note: replace with part
number on IC (they depend on model)\\\\
Magnavox\TP3281C101\Dead set. The power LED may flash.\\\32D700\One possible
cause is the flyback
transformer(5630). First attempt to read the LED flashes\After the long on
flash* count the *off* flashes.
Use the Service Manual to look up the indicated fault\CAUTION: WITH AC POWER
REMOVED FROM THE
CHASSIS:\Examine the case of the flyback for bumps or bulges on the cylindrical
part.\Any indication of
expansion means the flyback is defective and must be changed.

Make : Philips

Chassis : 27D7
Battling this beast.....Dead set....B+ OK on the HOT. New Flyback. Changed
Video processor ( TDA8846N). All usual SM parts and high failure parts
check OK. Even changed the vertical output.
Could use the Sams on this one? Anyone have the Efact they could share?
