Question about Sony Televison & Video
Have the back panel off. Want to check voltage to see if logic board is bad. Watched a you tube on fixing Sony Bravia. He checked voltage and voltage was 3.3 volts. He replaced the logic board. The model he had was older the mine. After pulling off the back panel mine does't anything like the one he worked on. Don't know where to check for voltage.
Look in the circuit board area where the power cord mates with it for capacitors that have bulging tops (instead of the flat tops that are normal). If you see even one, you need to replace all the large capacitors othe power supply section (normally around 5 or 6).
