Philips 42PFL4606 No Backlight
Hello Guys
This time ive got an 4606 again but with totally different issue
When powering on the unit you see the logo for an few second and after that only with an flashlight, ive tested the tv with an 47 SMPS and the all is working fine, So problem must be located in the 42 SMPS.
When measuring ENA and DIM i get 4,9V and 2,6V this while the tv is powered on.
Also between PIN 17 and 22 iam getting an High ohm reading 83K.
Which section do i need to check ?... -
