TV was working fine when we went to bed Monday (August 30) night. Got up the next morning and turned it on. It appeared it was going to come on, the green light flashed and then the lamp indicator light...
1. Red status LED, self-diagnosis error 44,
check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red
lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1
and 2 on the Engine Driver PCB if missing replace the Power PCB part #
930B921002 3. LED stops blinking after 70 seconds of plug in but will not power
on. This model is equipped with a keyboard lock feature, this can be mistaken as
a no power condition. To unlock the keyboard press and hold the "menu" button on
the front panel for 10 seconds 4. LED stops blinking after 70 seconds of plug in
but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the
Control PCB, if low suspect problems with the switches/buttons on the Control
PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will
not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4
check good. Suspect the E2P PCB part # 934C121001 6. (LED does not stop blinking
after plug in) Disconnect the USB connector from the card reader to the front
from the Chassis, if the LED stops blinking after 70 seconds replace the Card
Reader part # 299P271010. 7. (LED does not stop blinking after plug in)
Disconnecting the USB connector from the Card Reader did not help. Remove
connector FC from the FMT PCB and plug the unit in, if the LED stops blinking
after 70 seconds with FC removed suspect a problem on the FMT PCB (part #
930B924002), if the LED keeps blinking with connector FC removed suspect a
problem on the DM PCB (part # 934C116002). 8. (LED does not stop blinking after
plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4
(1000 UFD, 16V, 105C), if any are bad, replace all of them with part #
181P734030 (680 uFD, 16V, 105C). See Service Tip VS-78A 9. (LED does not stop
blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21,
C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with
part # 181P734030 (680 uFD, 16V, 105C) See Service Tip VS-78A
