fuzzy picture in sony projection tv

[lao 3]

Hi,

I have a kp-51hw40 projection tv. It used to give very sharp pictures.
Since yesterday, somehow, the pictures quality degraded to be quite fuzzy.
I tried to do refocus several times withou any success.

Any ides of what could go wrong here?
Your suggestion will be much appreciated.

Poor Signal, Change in focus or g2 voltages, video problems. Is the quality
of the display poor with the on screen menu data being displayed and the
programme material or is just the displayed video distorted? Is the
distorted video only via the tuner or also via the avio and composite
inputs. Many variables haven't been addressed yet causing your question to
be a bit vague. If the on screen menu is clear and the programme material
distorted then it may be the signal quality. if it is only via the tuner and
not the avio then it may be signal quality or tuner. if it is poor only via
avio but clear via composite then it may be the source presenting the ntsc
signals to the set. Again, too little information has been presented to
actually allow one to completely assist you. It may be prudent to have a
technician actually evaluate the set for failures.
