Hi everyone,
My first thread. Bought new just over two years ago with one year un-extended warranty (i.e., out of warranty) the t.v. was powered on, went through the Android loading screen - displaying the animated coloured orbs forming into the word "Android", started to display the picture from Virgin Media box - then immediately shut down - no sound, no picture and the S.M.A.R.T indicator unit at lower edge of screen displayed 4 flashes of red - pause - 4 flashes etc., etc.,. Switched off, powered on - same symptoms. Powered off overnight, disconnected from mains - switch on - same symptoms - t.v. displays Android loading animation then switches off (no longer displays a t.v. picture (i.e., Virgin etc.,)
Obtained repair manual - fault indicates (in likely order) 1. LED Driver board, 2. Main A/V logic board (main PCB), 3. Power board (two of : A & B)
4. Screen (WTF)
Have substituted 1 - 3 - exact same symptoms.
Have stripped screen, exposing the three banks of 72 LED's (216 in total) - the middle board (centre / bottom) has three failed LED's (I am able to power up LED panel with T-Con disconnected - defeating VCC test??)
In short, I need the (ideally) three panels replaced with new or a donor component for supply of the oddly shaped/sized LED's.
Easy enough - no.
I am so far unable to obtain the boards from anywhere, I am unable to identify/source the individual LED's, I have yet to hear from Sony regarding any 'fix' for my unwarranted 2 year old t.v.
Anyone with similar experiences and offers of advice would be greatly appreciated. The LED boards are stamped "NLAW50350 with either LS2/LS3/LS4" and the number "5071201-212-0577" - Thanks!!
