Question about Sharp LC46SB54U 46 in. LCD TV

Sharp LC46SB54U TV will not power on

The TV was working fine and suddenly it went off and doesn't come up again after several attempts.
I checked for loose connections etc and everything seems fine.

The green light doesn't come either. I suspect power surge. Can some expert advice me on how to fix this?

Thanks!!!

It can be as simple as a blown fuse in the main power supply module, if you get not indicator light at all, then it will be the power supply has gone out, if you do get some indicator light, the 5v standby power supply is still functioning but not the main section of the power supply module. The filter capacitors look good, no bulging tops?

You have to setup the sound to go to the aux out on the TV. Either digital, Optical or RCA in order for the TV to route the sound to the correct output port.

Cant remove stand from LC46SB54U - dont see 2 prongs going into back of TV...this is what my model looks like. http://lcdtvsale.devhub.com/blog/167586-sharp-lc46sb54u-46-inch-1080p-lcd-hdtv/


Look at page 7 Quick reference section
for similar model here:

If the mounting mechanism is similar you will need a hex key and loosen 2 pairs of screws on the back near the bottom. The stand should then slide out from the bottom edge.

Sharp lc46sb54u will not turn on, I hear clicking inside a couple of times like its trying to turn on. Then power an OCD button blink 3 times over and over. Help!!!


It sounds like you only have the standby 5vdc circuit working, first place to look is the main power supply module, or it can be the main circuit board.

My sharp lc46sb54u 46 in.hdtv power light keeps blinking


Any indicator light on at all, if you see the light, then only the 5v standby power supply is working but not the main section of the power supply, it can also be the main control board hat is not sending signal to turn on the main power supply section.

It sounds like the backlight inverter board went out, or the main power supply that supplys the power to the inverter board.
