The speakers work but at a very reduced level. Turned all the way up we can barely hear. It happened all of a sudden. When speaker level is on 100, it is barely audible. I tried all audio settings but...

Could be either an amplifier failure or a short in the speaker connection. For the latter, try removing and cleaning the speaker connections at both the unit and at the speakers. Then reconnect the wire, being sure to return the leads to their former location such that you don't accidentally reverse the leads.

Read Each Step Completely - Make Sure 3 Color Guns Are Off And Cool -
1. Remove Rear Dust Cover 2. Remove the Front Speaker Cover May be Held In By Plastic Pins and or Anchors on the Bottom Note" - Remove The Plastic Cover Just Above Speaker Cover Maybe 2 Piece.

NOTE"- May Have To Remove plastic Cover Frame positioned Around Front Screen And Then Remove Screws. 5. I Use Windex Glass Cleaner And Either Cotton Balls Or White Tube Sock On Color Gun Lens Covers And Clean Mirror Like The One In Bath Room. 6. Take White Sheet Or Bead Spread And Anchor On top Of TV With Weights, Stretch Around Each Side Of TV Use Chairs To Anchor On Each Side Of TV. Place Dust Cover Or Heavy Card Board Where Plexi Glass Was Positioned. 7. Turn On TV - go To Rear and Now You Can Adjust Colors Brightness And Low Light - High Light - Horizontal - Ect....While Looking at Picture. 8. Install In REVERSE - Order Just Wipe Color Guns Lens Last. Note" - If you have Wet/Dry Vac or Fan Or Blow Dryer Take A 2 - to - 3 Inch Paint Brush And While Brushing Circuit Boards Any Dust For That Matter Blow Dust Off And Out Even Brush Speaker Cover"...ECT...Do This Before Any Cleaning 9. Just A Thought If You Ever Want to Change Color Gun Cooling Oil - Wrap All Circuit Boards With plastic Bags And then I use Bath Towol And Paper Towols To Catch As Much Spill As I Can And Then Spray With Windex To Make Dry While Blowing Air Onto Spill - Also I have Found Clear Mineral Oil Like Johnson Baby Oil To Work As Well If Not Better Then Glycol Oil. I Get For $2.50 For 20 Oz Bottle.

Need to remove the screen on ws55859 to clean mirror and lens, it is almost 10 years old and time to be cleaned.

Remove front speaker grill(s) at the bottom of the screen behind the speaker grill you will find four or more black screws hold the bottom in. Look carefully to see the front keyboard needs to be unplugged---usually one or two different size plugs; you may have to remove the inspection plate located in back of the speaker grill to get to the point where they can be disconnected, with the keyboard disconnected the entire screen lifts straight up(you need to bring it up 3-4 inches and then it comes straight out(there are two hooks on either side that it goes into--when you finish line up a little and slide it back until it is back in place.

Clean the mirror with glass cleaner and the lens can be cleaned with a lens cloth or with a paper towel with glass cleaner sprayed on it.

Replace the screws and the speaker grill unit for the set.

I do this here for free so if this helps you give me a vote here.

Green ghosting on the side of images, sony kp43175

this could be caused by a magnet thats too close to the tv, like in an unshielded hifi speaker. if not, then a degausing component if faulty and needs replacing by an engineer.
