Controversy
While capable of producing good high definition picture quality, Sony have had problems mastering the technology of mass-producing the rear projector version of these displays. A high failure rate of the optical block has required repeated replacements of the optical blocks on some televisions. Sony previously settled a class-action lawsuit filed by owners of the first generation of the SXRDs, and apparently failed to fix this defect. Sony ceased production of all SXRD rear projector sets, as owners of most second-generation sets filed new class-action lawsuits. The second generation class-action suits were recently filed and are pending in Federal Court.
