Cant get sound


Hello,

This can often be as simple as the speakers being unplugged, plugged into the wrong jacks, or powered off, so don't overlook the obvious and check to be sure. Also check the volume controls in Windows or your application to see that they are turned up and not muted. When you are sure the volume is turned up, the speakers have power and are plugged in, and the speaker configuration is correctly identified in Windows (some audio hardware uses a proprietary mixer control for this job), you need to verify whether the problem is with the speakers or the sound card. Connect different known-good speakers and see whether they work. If they don't, the issue is in the sound card-possibly the configuration of the card is incorrect or the card itself is defective. The first thing to try is clearing the ESCD in the BIOS Setup. This essentially forces the plug-and-play routines to reconfigure the system, which can resolve any conflicts. If this doesn't help, try removing and reinstalling the sound card drivers. Finally, if that doesn't help, physically remove and replace the card from the system. You might try replacing it first in the same slot and then in a different slot because timing issues can sometimes exist from one slot to the next. If that doesn't work, you must try replacing the card. If the sound "card" really isn't a card but is integrated into the motherboard, first try the ESCD reset and driver re installation. Then, if that doesn't work, you have to try disabling the integrated sound and perhaps installing a replacement card.

I hope one of these solutions help.

I have a LG computer moniter and it just wont turn on i press the power button and the blue power light doesn't even stay on for a second


First Check your AC Plug if it is perfectly inserted. if inserted perfectly and still doesnt work, try using a working ac plug to check if your AC plug was the problem. If the monitor still doesnt work try checking you video card. Remove your video card and try cleaning the gold bars using a White Eraser. Insert the Video Card Back in and try running the computer. If it still doesnt work that means your monitor is the real problem.

if it is completely dead, then it could be a micro lock up.

take of speaker grille

unhook that connection and plug the tv back in
wait 2 minutes

the tv may now work with the remote, the buttons are bad, common mits issue.

if this doesnt solve, or you have flashing leds, let me know.

Yamaha rx-v461 not working


you have a faulty circuit somewhere, whether its in speaker wiring, or power source, i dont know, but your reciever has an automatic circuit breaker in it for protection, and a faulty circuit will trip it, i would assume it is a power source problem since it wont turn back on, check wiring, plugs and look around, and smell for burnt, or hot components.

SA HE200 ~ Overload at power up


First of, be sure volume is turned all the way down before or as you are powering it it.
Second if that does not work disconnect all speaker, and input/outputs.  Power the device on and see if it says overload.
If it does skip the rest of these steps, your capacitors are bad or the power supply is no longer functioning correctly.
If it doesnt, start with testing each speaker at power up.  Match the speaker to the output it goes on, power the device see if it says it. 
If it does on any speaker test it is a speaker issue or a terminal issue.  To test for terminal or speaker issue plug a different/ known to work speaker in that same terminal, if it doesnt say overload it is a speaker issue, if it does say overload it is a terminal issue.
Once you have made sure all speakers and terminals work correctly start plugging input and outputs in and test individually.
