Sharp LC-37D4U, the monitor doesn't turn on

Hi, I have a Sharp Aquos LC-37D4U, the problem is: the monitor doesn't want to turn on and the power light (blue) blink 3 times , then stop for 2 seconds and blink again 3 times, and keep doing that. Also the green light (opc/dl) blink 1 time, stop for 4 seconds, and blink again, and keep doing that. When I try to turn off the TV it doesn't want to do it, so I have to unplug it. I want to know which module is not working to replace it. Thanks

SOURCE: No POWER

How many times does the POWER led flash per second? (Dont worry about the OPC).

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)

SOURCE: Sharp LC-26D43U Power light flashes and unit won't turn on?

It's a power supply related problem. When it turns itself off, this it called protection mode. The TV automatically turns off to protect other parts form being damaged.
The most common problem is the Power Supply Unit or the Backlight Inverter Board.
You may have to take the TV to a repair shop to find out which one is bad. Paying a repair shop to replace the board for you maybe more than the TV is worth. If you let them diagnose it and you replace the bad circuit board yourself, it would be cheaper.

Here's a place I use to get parts for TVs:

The problem is the repair shop may charge you double or three times of what the part costs at the web site link above. Then, plus labor. I just want to save you money. :)

Do you get any indicator lights at all, if you do, then the 5v standby circuit is working, if you get nothing at all, then the main power supply will be the first palce to look, blown fuse? capacitors?

Sharp Aquos 37" LCD TV sound quit


You could open up the TV and look for signs of burnt components then try to replace the components or try to find a replacement for the entire affected board on ebay or something. If you can find out what the problem is maybe the service person will lower there price. $600 does seem very steap, it should be something closer to $60 an hour with maybe the first $60 as an estimate.

I have a sharp aquos lc-c4677un its not turning on at all now. When I push the power botton on the tv, the power light turns on and about 2-3sec the power and opc light start to blink and thats about it.


How are the power and opc lights blinking? Do they blink simultaneously or does one blink then the other? How many time do they blink per second? Also have you had it fixed yet? and if so what was done? I had a similar problem with my set.

My sharp aquos lc 37d62u will not power on; the power light flashes 4 times, pauses and then repeats the 4 flashes. Does anyone know what this error code means? Thanks!


It is detecting shorted circuits or power supply problem, need in-depth troubleshooting. Inspect the power supply module first for any sign of bad caps with domed tops, DC output voltage readings check.

You have standby 5vdc but you need to find out if the processor board is sending out the PS_ON to the power supply to turn on the 12 and 24vdc power supply section.
Heres is the service manual and training manual for your TV.

Sharp Aquos 32 wont turn on


I called up Sharp, and if you are a part of Sharp AQUOS Advantage Program you get free in home service.

They were very nice about it, and I already have a technician coming to my house on Saturday and I called on Wednesday.

I doubt Sharp's policy alot less now!
