Question about Sony KP-57WV700 57" Rear Projection HDTV
When I go to a channel, the image displayed is darker for a few seconds and then lightens. I believe overall all of the images are darker than they were previously. Bulb going bad?
Also, blue lines arcing across dark (usually black) backgrounds are displayed.
If the coolant is cloudy or has debris floating in it, the coolant will have to be changed and the lenses and crt face will need to be cleaned. Coolant can be ordered from any electronic distributer
