Subject: [TechAssist] F8 Chassis Dead - Relay clicks 5 times?
What: 27" Color TV
Make: Magnavox
Model: MS2730 C221
Chassis: 27F800-7583
Made: March 2002
Problem: When you hit the Power button on front, the relay "clicks" once
then "clicks" FIVE times and quits. The Front LED lights "once" with the
first relay click, then goes out, then lights once more again while the
relay clicks five times quickly, then goes out for good. High voltage is not
coming on.
I replaced the STV9379FA Vertical output IC and checked R3488, R3486, R3487,
R3491, R3492, all diodes in the area, checked all pico fuses, checked for
cracks on the pcb and bad solder, replaced the common R3340 on the CRT
board. This is sounded like the flyback. Anyone experiencing this before?
