Sharp Aquos LC-37HV4U 37 in.  LCD HDTV Logo
Holly Nonesuch Posted on May 10, 2014

Why does the power light on the front of my sharp aquos lc-37v4u blink red once per second? Why won't the TV turn on?

I had the TV on yesterday and it worked fine. No issues with picture or sound. Today I went to turn it on and no go.... the red power light on the front of TV is blinking 1 per second and it seems the "main power" button on the top right is not staying down in place. Is there a way to set the button and/or the TV? Thank you for your help. Holly

Call sharp back again and tell them you first want to register for aquos advantage program, which is free. By doing that your service will go much quicker with them. You then tell them that you want to get set up for service. They will have one of their authorized professionals come and fix your tv in a matter of days. If their tech cannot fix it, they will replace your tv free of charge as long as you are within your warranty.

Right now your TV is in " Protection Mode " because of a failed part inside. The blinking red light is a error trouble code. Only someone with the actual Service Manual for the TV will know what the code means. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common board to go bad is the Backlight Inverter Board. It what supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Sharp Aquos LC45GX6U & TU-GD10U. The unit doesn't power up, and has a red blinking light from the moment you plug it in. The unit works fine in service mode.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Ok.... I got a new power supply board and the tv is still doing the same thing. (Sharp Aquos 37in LC-40C37U) So if it is not the power board then what could be wrong with it. I'm getting no power and only...

The pattern of the blinking is a code. If the power light is blinking by itself once per second or thereabouts it could be loose connection to Inverters, reload firmware, Inverter Unit or LCD Panel.

Sharp lc-22sv6u won,t power on. no green light.

Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

You either have broken power board or main board. Power board - blinking 2 per second, main board 3 times per second. In an case it has to be fixed by a technician.

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

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

There isnt really anything you can do to fix it yourself, youd have to call Sharp to locate a local service center.

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)
