Need to fix Philiphs model 60p8341 ptv915

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

Replace sound Ic

HI I AM HAVEING PROBLEMS WITH THE VOLUME THERE IS NONE AND NONE OF THE BUTTONS IN FRONT OF THE T.V ARE WORKING HELP PLEASE

Your TV needs the part 313501707611 - it's the keyboard that's the cause of your problems - but here's the catch... Philips does not make that part anymore... they say that you need to either find someone to fix the keyboard (which I've had no luck on) or buy a new Television from them... hmm, a $2000.00 TV that needs a $20.00 part now becomes a plant holder in my living room because Philips wants us to purchase a new TV from them.
