Hi All
I was watching my TV when I heard a crackling and slight hiss and the picture pixelated and the everything turned off except the LED. Hoping to get some help to diagnose what could be the matter. Below are more details and also info about what I have checked so far.
Plugged in turned on via button on side the led just pulses on and off I guess you could call it a slow flash
Model
LG 42LD560 - TA .AAUWLJD
PSU PCB
EAX61124201/15 Rev 1.2
Barcode sticker number
TA9AE608694023536 (1.2)
Main PCB
EAX61768307(0)
BCM High
LB03B/LJ03B/LL03B/LT03B
What I have checked.
Electro Capacitors on PSU seem to be fine no puffiness. Also seem to charge up when meter is used only to 3v though. No real visual clues to what let its magic smoke out.
Main PCB connector voltages
measured 12v yes
measured 3.5v yes (3.4v ish measured)
measured 20v no (nothing present will double check later)
didn't measure (will update)
error
P-DIM
A-DIM
INV ON/OFF
POWER ON
Any help would be greatly appreciated.
Cheers
Christian
