You don't have an inverter module in that set. I believe you meant to say convergence module. You cant buy those anymore, they must be repaired to component level.

TV won't turn on, when you turn it on the green light comes on, you will see a light as if the TV wants to come on but then it shut off and the red light flashes.


You probably have some defective capacitors on the inverter board, possibly along with a blown surface mounted 10 amp fuse. If the red light flashes a particular sequence then repeats, it may indicate a specific trouble code.

Status indicator flashes 3 short times, then one long red flash


Once the status light blinks 3 times, this is an indication that there's a problem with the lamp. The lamp may need a replacement.

If you replace the lamp, but get the same problem, check the inverter board.

If you're not sure where the inverter board is, then you may need to contact a pro for your safety.

Good luck and have a good evening!

Same problem. red light flashes 3 times, but will not turn on.


Hi,

The blinking light means the controller QA01 in the AV_TERM system board is booting and driving the TIMER/REC RED LED light accordingly. This failure mode is true for many conditions, not exclusively for the main PS board PE0071. It could be caused by many things, LOW B, SEINE, AV_TERM, LCD, PROTECT, etc.

Specifically for PE0071+12VDC circuit failure, which is the most common , listen for the LINE relays SR80, SR81 coming online. If several (3) or more clicks are present when applying power to the TV set then suspect the +12, 20, +32 VDC inverter is faulty.

As a quick check, you can disconnect P807B. If the relays cycle every 1-2 seconds then is most definitely the +12VDC inverter. Check for voltage level at optocoupler Q881 pin 4 and this should not be cycling. This point is the VCC for the oscillator. Repair or replace board 75002913 as necessary.

TROUBLESHOOTING: (this is my own, not the OEM !, try at your own risk!)

  1. Check for LINE1 input voltage level at inverter on sheet [4].
  2. Check for LINE2 input voltage level at inverter on sheet [3].
  3. Check for STBY +5VDC & +25 VDC ( observe correct GND REF) page [4]of PE0071 POWER
  4. Check for +22 VDC out of regulator on page [3] out of Q822 Emitter
  5. Check P809B connector for :
  • P809B (12) POWER = 3.00 VDC (+/-0.2)
  • P809B (11) POWER_SIG = 0.00 VDC (HIGH to Power on TV)
  • P809B (10) PROTECT = 0.00 VDC
  • P809B (9) ACDETECT = 3.00 VDC (+/-0.2)
  1. Check for PFC_OUT = 368-371 VDC
  2. Check for +12, +20 & +32 VDC inverter page [5] of schematic manual.

For +12 VDC Inverter, suspect components:

Q880 STR-W6765 PSR (works really hot!!)
C888-C890
D884A and related switching circuit components.

Good luck,

Insignia NS-32LCD Backlight or Inverter bad???


If you've done the flash light test, it could be the inverter board became defective but it could also be that the power supply does not provide the +24VDC to the back light inverter board.
If you could do the +24VDC test using a voltmeter then we can say for sure that the back light inverter board is defective.
Let me know if you need further assistance.
