Re: sony kp-57ws510

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.

Can you do this? Take the back off and look next to the transformer (has large red wires coming out) and have someone turn on the set and if you see a glowing device next to the transformer then the High voltage splitter is bad and if no glow then transformer is bad. This is for information purposes only. Changing these parts is for the trained only and could cost on average $300 parts and labor depending on the repairman and location you are living.
