hey guys, i have a logik mp-421 lcd television that wont power on
the tv itself will go to standby when power is applied and the red light will go blue when power on is pressed on the remote but the display self is dead, no backlight and no display on panel even when lit with a flashlight.
ive stripped it and checked capacitor for faulty ones but theyre good, but that ive found was a small blue 1kv capacitor cracked in the middel, replaced it but same problem.
also theres this humming/buzzing/squealing noise on the AC input side right by two transformers.
Ive attached two images, circled in red where the noise generates from, its faint when tv is off but goes louder when switched on.
