Question about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV

1 Answer

I have a Sony KDF-50WE655 with blue specs on the screen. I have heard that it is some kind of optical thermal piece. Any ideas on how to fix it.

    We have blue spots , most visiable when watching golf, notice it on green background.

    I also have blue specks, kind of like a shotgun pattern within an overall bright blue aura on the left two-thirds of the screen. This came on rather gradually, but now is very noticeable and very objectionable. I have replacd the projection lamp, but this condition started prior to the old lamp burning out.

thats a common symptom for that model which is usually related to the optical block. Very exspensive repair. Check with a sony authorized repair center as Sony has recognized the problem and offer assistance with certain models yours may be one of the ones affected.
