Question about Sony KP-57HW40 57" Rear Projection Television
When i turn on the tv it´s good but in 1 minute or less the blue and green starts to fade until the screen is all red, i take a look behind the tv, they are still working but with less intensity.
The sight in Jean's posting could help. Usually 5 blinks signify that the voltage is too low so you may actually have to turn the knobs up then back them off just until the retrace lines disappear. If one color dominates and you see retrace lines, you may want to turn that one down. But if the dominating color doesn't show retrace lines the other 2 might need to be increased slightly. If you Google Sony TV flashing led codes most likely you will come across an explanation of the codes. Hope this helps.
Please keep in mind many things can go wrong with TV sets and you should really do a lot of research before attempting any adjustment and or repair. There are high voltages present in some areas and they can reside even when the set is unplugged.
