Question about Sharp Televison & Video

1 Answer

I own a Sharp Aquos LCD model LC46D43U. It's 3 1/2 years old. When I turned on the TV, the power does not come on. It clicks like it's trying to power up and repeats itself 4 or 5 times every 4 - 5 seconds. Then afterwards, the power light and the OPC light flash green 3 times simultaneously. I've unplugged it, tried again and still no solid green power light nor picture. Thoughts?

There is a problem with the power supply. most likely too much ripple that is ac leaking into the dc. I have seen the power supply repaired but it is not always possible. If there is an obvious swelled capacitor on the power supply that can be replaced this will be the best bet for repair. If there is nothing visually obvious then it gets a little harder since you won't really know which component is not working, the tv shuts down on a protection circuit so if the power supply can be repaired and the voltage "cleaned up" then the tv could work again. I have also seen replacement power supplys sold.

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!

TV wont turn on blinking power light


The powersupply is going bad. If it's within a year old it's probably under warranty, if not look on ebay for "aquos lc32g4u power supply" or "aquos lc32g4u parts" and then replace the powersupply.
