There are a few reasons that pic goes out on this set. First convergence problems, meaning amp need changing, but most of the time it gives you some kind of indication before it goes out, like color problem converg. not ligning up. Second it could be verticle output gone out. This is a 7 pin IC located at back of set on heat sink. Third the sound amp is going out. This could be an indicator but most of the time you don't have any sound. But still could be a problem

My pros can ps56670 makes a popping noise when I turn it on but won't come on no picture


I just answered this for someone else; this sounds like a power control board problem. Basically something has short circuited and if you're hearing popping from the back and not the speakers it a power problem. If you're hearing it from the speakers but no picture then you need to replace your control board.

My hyundai plasma turns on, but has no sound or picture. It's a 2006, Model E420D.


Power supply is likely but if master power and not just the regular on off has to be used set is having a control problem. Power supply would be first place to look---even if green light remains no sound might mean control (main board) or power supply issue.

I have new computer. My Yamaha speakers Model YST-M7 are older. There is power to the speakers but no sound is coming out. Not sure which hole to plug them into. My choices are: rear l/r surround...


Use the "line-out" connector (usually it's light green in color), and if there is an audio control panel application, make sure the sound circuitry is set for "two-channel" or regular stereo speaker operation. It can be confusing on newer computers which have surround-sound capability built in. Depending on how you set up the sound, the jacks can have different functions. But the line-out jack is what you'll use with basic speakers such as yours.

Hi,
Looks like your volume control switch is not working on the left side, you can check it by tapping the knob on the volume control and sound will come out on left side.
The only way to get the sound again is to replace the volume control or pull out the volume control and open it up to clean the contacts in it.

Hope that helps you out!
Thanks for using Fixya!

SPEAKER OUTPUT CHANNEL FAULTY, TWO MIKE CHANNELS DOWN


These are a real pain to open. You have to remove the front panel to remove a shield to remove the back amplifier power supply area. The power supply is a switching type and has lethal voltages present. Working on this should be done using an isolation transformer. With your symptoms, it is likely one side of the power amp MAY be blown, but do check that the wiring hasn't fallen off and the jack itself. Two pairs of wires come from the power amp to the front panel jacks. document location of ALL the cables you disconnect as they CAN be confusing to restore.

Trouble with rear speakers


This may be a software issue. If you only had two speakers before, the software will not use the rear speakers.
Go to Control Panel. Click on "Sound and Audio Devices". Under the Volume Tab, at the bottom, you will see a picture roughly representing the type of speakers.
Click on the Advanced button.
Click on the arrow in the pick box, and choose Surround Speakrs or the 5.1 Speakers.
Click Okay. Try the speakers again.

Sound not coming from left side surround sound speaker or my right side front speaker


it is highly likely that you're TV is outputting mono sound, hence the left channel only. check your physical connections to the TV and the balance / channel volume on the television as well.
