I have a sharp lc46d43u the power light is green, have sound but no picture and none of the buttons work except the power button


Have you had a power bump or spike just prior to your problem. If so I would call the support for that TV and ask what the reset pattern is for the set. It can very from manufacturer to manufacturer.

I Have a 5.3 IR Remote and a vizio VSB200 Sound Bar. The remote will not program to the Sound Bar. The Optical Audio is connected to the TV. What do I need to do.


lojr,

We have code to use with amplifiers, TVs, VCRs, and DVD players. I do not have a code that will work on this sound bar. What is the code you are trying to use? Did Vizio supply a code with your sound bar. They do have codes to use for their TVs to program DISH remotes. Please let me know if you have a code or you can contact Vizio to see if they have a code available.

I have provided the Power Scan instructions on programming the remote to a sound bar. Use the VCR button to attempt to program the sound bar.

If you have further questions, please post it here.

My computer was running very loudly, for a couple of days, than one morning after working properly for a few hours the power went out and it won't even turn on.


does it make a sound when you press the on button? cause if not you might have a problem with your power supply.
if it does make a sound it might be motherboard problem.
if it makes a beep(ing) sound(s) it could be fixed most of the time for under $100 no promises:)

just in case try to unplug the power from the computer >> hold the power button for about 20sec >> plug the power back in and turn the computer on see if that works.

post back with a bit more info such as what you hear when you press the on button (any sound at all even its a short one).

Dv6120us power button dont work


None of the buttons will work untill the power is turned on and no sound will be heard.
You might want to try charging the battery by connecting the AC adapter to the laptop and plugging it into the wall outlet.
With the AC adapter connected, try powering up the laptop.
I hope this helps.
Good Luck.
