SOURCE: i have a sharp aquos model Sharp Aquos LC-20B2U 20

if your TV lights the indicator when you power it on,, your problem is your back light is busted you can replace that and when the indicator not lights the problem is your power supply you can fix it by finding defective parts by using multimeter usually the trouble that i encounter to power supply is open/change value of resistor leak capacitor and shorted diode and transistor such as regulator you're always welcome

SOURCE: How to connect my Vizio vsb200 to my sharp

This television does not have audio outputs so you wouldn't be able to connect these two devices--well the one digital audio output this television has is not compatible with any of the inputs on this Vizio. Double check please by looking for a hole/input on the Vizio that will match up with that on the Sharp television. If I am wrong and there is one then you would need the digital audio cable. I believe this television takes a coaxial digital audio cable, and the hole that would correspond to this cable on electronic devices is normally black in color.

If I am correct and there is no way to connect these two devices directly then you would connect your devices to the Sharp television for video only and connect their audio cables to the Vizio's inputs.

My Sharp LC-42SB45UT Television was on and the sound on it just quit.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Sharp LC-52SE94U shuts down and restarts automatically

There is a software update for this model via the Sharp website. Included is a link to the compressed folder. Once you uncompressed the folder there are instructions in the folder on how to install the update. It doesn't specifically say this is a fix but as a TV technician personally its the fist thing I would try.

Random turning off/on while watching tv

sounds like it could be a power issue. is the powercord on the back of the tv detachable? make sure its plugged in tightly. also if using a surge protector reset surge protector. if not using a surge protector try a different outlet. also if gfci outlet (has reset button on outlet itself) try resetting the outlet by pushing the reset button

T.V. turning on

yes my 26" sharp aquous LCD does the same thing, turns itself off and on at random times without explanation. I sent to authorized service center they replaced the power supply under warranty then it failed within 6 months and neither the repair center nor sharp will do anything about it other than sell me a new powersupply for $425.00. I have contacted a power supply repair center in Texas who has vowed to fix it once and for all. We'll see in the next week if they fix it or not.
