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. :)

Backlight invertor is most likely cause of the problem, in rare occasions defective CCFL lamps could cause similar symptoms. Replace defective parts, reset lamp error counter and you good to go.

Why won't my LC-C3242U Sharp Aquos tv won't turn on


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

My sharp aquos lc-c3242u turned itself off and now wont turn back on. i plugged it into a different power receptacle and the green light flashes but wont turn on. is there a way to reset the tv, or is...


If power light continuously flashing it means backlight problem. Two possible causes. One, backlight invertor is faulty. Two, but realy rare, one of the CCFL lamps went bad.

Sharp LC-26D43U TV. After power is turned on the power light comes on for a couple of seconds and then there is a click and the power light blinks 4 times then pauses and repeats the 4 blink sequence......


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.

Sharp Aquos LC-C3242U power issues


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?

Set up only visible for 2 seconds, then black - Aquous lc-37d43u


Unfortunately I can promise you that you CANNOT repair this. Your power and opc lights coming on, but the tv is not coming on. That is a issue within the tv. Give sharp a call and they will have somebody come fix your tv free of charge, if they cant fix it, they will replace it for free. That is the only thing you can do. Sorry bro
