Question about Sony Grand WEGA KDF-60WF655 60" Rear Projection HDTV

1 Answer

Fixed Blue dots in central screen, blue fringe in lower left

My Sony KDF-60WF655 recently had a blue fringe in the lower left corner of the screen and then developed blue dots across the central screen that are fixed in place.  I could not find any troubleshooting guide for this.  Is this a lamp problem that will be corrected with a new lamp?
