Question about Sharp AQUOS LC-45D40U 45 in. LCD Television
I'm believe the 2 flashing code specifies a problem with the power supply. It is possible that one or more of your supply voltages is out of wack. Have the power supply tested.

SOURCE: No power on LC32D50U Sharp
bobnyc, Is set under warranty? How old is it? Did it display a "perfect" picture yesterday, and not today. How is or was the AUDIO. Can you hear anything or nothing? Is the SMPS power supply board a "COMBO" or is the INVERTER supply located elsewhere? To where do the CCF tubes connect to get power? Tell me, do u have a good DMM, 100mhz Ocilloscope, Isolation transformer, and soldering iron/ solder wick???? If have some answer to some these ??? contact me @ louie12fix on fixya or at lmistyrel @aol.com PS: I highly recomend use of digital cam to take pic's before taking stuff apart. Could help when reassembling.

Power board is detecting an 'over-or-under-voltage' condition from other circuits. Could also be high dc volt shut-down. In either case, the tv is in protection mode to stop further damage this is why it flash an error code 4 times. Each number flash intervals tells the tv-technician what area the fault may potentially be. take it back if its under warranty, or have a repair shop near you fix it.

Testimonial: "Took a part back panels looking at the circuit board power capacitors, plugged in TV to power outlet, and powered up normally."
This problems is very common on Sharp tv after a year or two.I have one too 46" Aquos.The tv Tuner signal board have problems,but this tv still usable.My tv does Power and OPC LEDS lights flashes alots many times as the tv getting older.This how i solved it.If POWER and OPC LEDS lights flashes,just press the remote power again wait awhile.Sometimes POWER and OPC LEDS lights will flashes again,just press the remote power button again and wait awhile.Sometimes POWER and OPC LEDS lights will repeat like 3 or 4 everytimes,just must press the remote power switch wait awhile eventually the backlight,will light up the Tuner signal board kick in and work.Have to press the remote power button and wait for the POWER and OPC LEDS to stop blinking and the Tuner signal board to kick in.But like POWER and OPC LEDS blinks 10 or 12 times and remote power button press 10 or 12 times,it time to replaced the tv Tuner signal board.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tv Tuner signal board for the replacement.

Start with the headset powered on. Press and hold down

For the Plantronics M1000 (discontinued):
Hit and hold the volume/mute switch in until the indication light starts blinking.

On the adapter press and hold the blue power button for 10 seconds. The light on the adapter will flash once after 3 seconds- continue to hold the power button for another-7 seconds until the light flashes red. If the pairing is successful, the headset will sound a tone and both the headset and adapter lights will turn off.
For both the Plantronics M1000/M1500 (discontinued): If you remove the battery cover from the headset and then remove the battery itself. On the Green PC board itself there will be a letter followed by 4 numbers. These 4 numbers are your personal PIN code.
