Question about Sharp Aquos LC-46D62U 46 in. LCD HDTV

1 Answer

The power suddenly went out on my Sharp LCD 45". The power button in front is blinking red. I've tried unplugging the power cord and I think I've pushed the reset button in the back with a paper clip. It's hard to tell if I'm hitting the so-called button without taking the Tv off the wall which is a hassle with all the cords attached to it. What else can I do?

My sharp XLMP 130 all of a sudden started blinking red four times and then one long one - nothing works??


The problem is with the "power on" relay (RL841) located on the power supply board. Unplug the unit and take off the side panel and top cover. Remove the screws to remove the CD changer. There is a small black rectangular relay just below where the AC cord is soldered onto the PC board. Carefully remove (actually break it off carefully and gently & throw away) the plastic top housing of the relay. Plug in the unit and with a pencil or stick, manually actuate the coil armature while pressing the power on button on the front of the unit. I can almost assure you your unit will return to normal operation. Put it all back together and you're done. The blinking red 4 times followed by a long pulse indicates a power failure. The start up capacitor had drained and couldn't provide enough voltage to pull the relay coil in all the way.

Sharp Aquos 32GA5U red blinking light in front but no picture!!!


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.

DLP projectors will not turn on


chances are the bimetal circuit breaker has tripped because the projector overheated. clean the filters frequently. if you take the top off (6 screws on bottom, 5 in back, but unplug it first), the bimetal is the red button on the front of the lamp housing. push the red button to reset it and put it back together. turn it on and enjoy!

Red light on power cord


try unplugging the power brick from the wall and the power cable from the 360. Then reconnect these cables and try powering the system on again. if the problem still continues, look at the front of the console, you should see a circular light. If 3 of the lights are solid red you will need to contact 1-800-4MYXBOX, as that indicated hardware failure.
