Customer Question

Issue with Sony KDF50e3000

Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, any error code / blink count ?

Still, proposed preliminary tries (if have not been done):

  • • re-check resistor values preferably out-of-circuit or even with just 1 leg lifted off the board - 3.3Ω/R6259, 4.7Ω/R6273, 0.47Ω/R6500, 0.1Ω/R6102, 470Ω/R6115, 22Ω/R6116 & R6117;
  • • does relay RY6001 engages;
  • • test for the presence of +319V @ pin 1 of connector CN6501.

A friendly reminder: voltage measurements by its very nature requires that the unit be plugged in, turned on and therefore LIVE! Please exercise due care and caution.
