Question about Sony KP-57WS510 57" Rear Projection HDTV
Test your power supply output voltages, make sure the step down transformers are not leaking high voltage into the dc circuits. always start at the basics then work your way up or out. the most common problem for these late model tv's is power supply they just dont use quality parts anymore. in older tv's you could hear the high voltage arcs, snap today its rare for that to happen. I have a 32 inch LCD here now that actually blew a 1500 pico farad capacitor with no noise. that amazes me thats a pretty good sized capacitor, and they usually make some noise when they blow the top right off of them.
