Hi Ninh,
I had a similar problem with my stereo receiver not long ago. The problem ended up being a short in one of the speakers. If your speakers are powered separately from the receiver, it might be that one of them was damaged due to the storm. The short would cause the amplifier to shut down as soon as the speakers are turned on.

The easiest way to check this is to disconnect all the speakers, turn the surround sound on and then reconnect them one at a time to find which speaker is causing the problem.

Hope that helps.

SOURCE: will not turn on

I have an RCA projection widescreen TV model # D52W19B and was watching when it made a pop noise and turned itself off. Now when you try and turn on you get a high pitch beep but TV keeps shutting itself off with no picture or anything. Could this be the bulb went bad?

SOURCE: Aquos LC46D64U, problems with av input video signal

You know, I've had two repair instances regarding this particular model line (D64U) where there were problems with only the analog inputs (such as the component/composite).... but with no problem with the HDMI inputs.

Replacing the Main Board fixed these TV's. Since both the Xbox and the Wii present the same problem on two separate inputs, this leads me to believe you most likely have a defective Main Board. If your TV is still under warranty, I suggest calling Sharp to locate your local authorized service center.

SOURCE: Akai Plasma TV's screen suddenly went blank -model PDP4294

Same thing for me. TV just turned off one day and won't come back on. LED flashes red. Someone said it's because a cooling fan went out. If I can't find someone to fix it I'll take it apart and tinker myself. 32" with dvd built in was barely over a year old.

SOURCE: laptop dead. power surge.

Hi there,
You need to reset the Power Management Unit. The instructions for most models are here:

Choose the one for your model part way down the page. Once reset you should be up and running again.

All the best

I have a htr 6130 yamaha reciever and when i hook my five channel home theater system it plays for a while then when i turn it up to almost max it turns the unit off completly... how do i hook up my


Hook all the positive and negative wires correctly and read on the speakers and make sure you have them all in the right spot and if that doesnt help its probably because the reciever is maxed out wich is triggering a kill switch wich some recievers have as a safety feature so you dont blow your speakers

I have a Panasonic HT-692 surround sound system. Any time I use the surround sound features and turn the volume to a higher level(not ear piercing mind you) the system cuts off as if a ckt breaker has


If you are playing the unit that loud, for an extended time it sounds like the unit is going into overload, meaning it's getting to hot. Try turning the volume down to 1/2 of your current level. If it stays running, you will have to cut back on your volume, before you seriously damage the unit(or your hearing)

I have a Fisher RS-909 Surrond Sound amplifier. It has no "sub out" jack. I had the sub-woofer working in the past by wiring it as shown in the manual. The problem is that the system was in...


Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

Sound only from left front and right front speakers possibly my projection screen tv is only 2.1 channel does this mean i cannot have surround


surround receivers are supposed to be able to turn a stereo signal into a surround signal.  if the surround unit is producing just a stereo sound, then the tv is most likely outputting in mono, and not stereo; or there is no surround sound to decode..

5.1 Surround Sound Cutting Out


HI,
Yes you are right man, this problem occurs only with the cable problem, i can explain you, if there is a receiver problem means you won't get the sound its dam sure,
only if there is a cable problem you will get some noise or sound cut off with the speakers, so you please check the cables properly it will be alright.

No sound from main left and right speakers


no, the yamaha system would shut down if the amplifiers had a problem. I would check the bose system, try directly hooking the speakers to the mains in stead of thru the bose system if you can. the easy way to check the amps is to plug in a set of head phone in they are directly tied to the mains.

No sound when using dish or regular tv


This may be old news but just in case ...

Typically you need to consider the surround system as the central point for sound distribution (and in newer receivers, the distribution point for video signal as well). So you need to think of your TV and Satellite as sound sources and connect them to the IN side of your surround sound system. From the back of your TV then, look for the Audio OUT (commonly Red for right and White (or black) for Left. Connect these to the IN on the back of the surround system. Likewise for your satellite box. Then make sure you select the appropriate source on the surround system. If the system supports the video signal, you can route that as well. Beware that you'll need some sort of simulation (provided by the Phillips unit) to upconvert stereo to surround ... check the manual online. If you post model numbers for the Phillips and satellite units, we might be able to direct you more specifically (provided we can find manuals online)

Only one surround back speaker works


It sounds to me like one of your speakers may be mis-wired. Try reversing the speaker wire (don't switch right-for left, but switch negative for positive) and see if that changes anything.
