    My receiver seems to be getting power (red light is ON on the front of box. But the Display will not power up. No red light - nothing. Tried the "Reset" and "System Reset" (described in the manual) but no go. Switched the power cords on the Receiver and Display, but no difference.


    Why are the other two reports here dated this month? (Feb 2009) Seems odd.

    si accende regolarmente ma non si vede nulla.
    Posso cambiare i canali ma non si visualizano.
    dopo circa venti giorni riaccendo il tv e tutto funziona regolarmente.
    dopo qualche mese di nuovo spenta.

This is glennac. I figured out what happened and thought I would update for others. The display had stopped working soon after mounting it to a wall mount. I discovered, when I began removing it to take it to the shop, that it started working again once I had loosened one of the mounts screws. Tightening it back in caused the display to lose power again. What I discovered was that there is a spot on the back against which the mount plate rests which, if pressed too hard, cuts the power. Backing the screw out relieved the pressure on this spot and now the TV works again. Facing the back of the display, the spot is at about the 11:00 o'clock position from the center, halfway between the center and the top.

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.

TV won't turn on


the first thing that you need to do is to open the back cover of your tv.Go to the power supply section it is separate board where the power cord is connected.Using a multitester,plug in the power cord and measure for the output supply.see if the 5vdc ,12vdc and 24vdc are present..if one of this output is missing,replace the power supply board But if the output voltage are complete,replace the inverter board,It is a board that supplies the high voltage to the backlights of your monitor/screen....You can also try to reset the system of your tv by pressing the the small switch mounted on the main board press it twice while the power is on...tnx and good luck!

Power light comes on for about 30 secs, something clicks and both power and ocp lights start blinking contineously. the screen does not light up


I have this model of the sharp tv.Happen to me very often the Power and OPC LED light indicators blink continueosly.Not the power supply board,it the Tuner board that take in the comming broscast signal that have the problems.You still can used this tv.Push the power button sometime the tv it will work right away.Not,each time POWER and OPC lights continueosly blinks.Just push the power button again each time the POWER and the OPC continueosly blinks.Just have push power button again about 4 times each time Power and OPC blinks recycles,it will finally show the backlight and picture come on.My guest,if u do this by pushing power button to recycles about 10-12 times each time the POWER and OPC blinks it time to change the Tuner signal board.

No picture, but power is on...


How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
