I am about to be getting a Sony Bravia KDL-46XBR3 that has the power-on black screen issue (as the person describes). I've read this can be an array of different issues from bad caps to faulty main, power, or inverter boards. I also have a KDL-46XBR4 that has a bad panel (bad tab bonds that I remedied once before). My question is, are the panels interchangable between them? For being so visually identical I've found that every board is different between the two, according to online results. If they are interchangable, could I easily swap the panel from the xbr3 to the xbr4, or likewise, would the guts of the xbr4 go into the xbr3 successfully?

I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
I do not hear any sound and I cannot see any backlight.
I have tried disconnecting every cable on each board one at a time to see if anything changes.
The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
My friend ordered another used power supply board but it is also doing the red indicator flash 3 times... -

Hello,
i have this sony bravia kdl-43w755c which boot loops. After sony logo, it shows the android animation loading then it restarts…
from what i read online it looks to be an emmc issue…
i’m not familiar with this kind of tv repairs… i’m repairing laptops and gpu’s…
i took out the board and say an samsung 16gb emmc
i don’t have an exact replacement, but i have a few 32 and 64gb emms’s from laptops…
i could try to put one instead of the 16gb one, but will it work?
where do i get the software from?
any help will be much appreciated!...03-06-2024, 12:26 PM -

hi everyone,
my parents in law have seen their Bravia Sony LED 32EX600 TV set stop after a lightning strike. After being plugged to mains, it shows nothing no power LED on bottom left shines.
On the power PCB (GE3b, attached pic), I chacked the fuses and the only roasted one is R6536 : 0.47 ohms, 1/2W. After replacing it, I made some voltage measurement with ref to the chassis :
- the 450V/150uF capacitor voltage when plugged is normal at 394V
- from connector CN6150 (15 poles)
STBY normal 3.3V -> I shunted it to 3 (POWER ON) and 11 (BL ON) and unplugged...06-28-2023, 02:43 AM
