Re: Sony Bravia KDL-40W5500 - 14 blinks problem
From what you provided the main cap is putting out 389VDC, which means the PFC circuit is on. You also say the back_light_on command, which comes from the main board, is 0V. At this point, I suggest you test the voltages at connector CN6150. If those voltages check good, then you could have a bad main board.Last edited by jetadm123; 03-04-2018, 03:05 PM.Comment

Re-reading your chart in post 16, it looks like your INV_ERROR pin has been triggered, which indicates a problem in the inverter section. Suspect this is what's preventing the BACKLIGHT_LIGHT_ON command from being sent. Check the resistor as budm/vinceroger69 suggested.Last edited by jetadm123; 03-04-2018, 03:22 PM.Comment

What's wrong with my TV: the TCON, the panel, or something else? I'm stuck.
Problem:
Last week, my Sony KD-70X690E 70" stopped displaying a picture. The TV powers on, and the back lights power on. However, the TV doesn't seem to boot up. I say this because the SONY splash-screen logo does not display, nor does any picture display, nor can I invoke a menu by pressing "Menu" on the remote. Other than back-light bleed, the screen is black.
My troubleshooting got me this far:
With the left-hand TCON to bottom-board ribbon cable... -
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... -
The TV shows a black screen with no image.
TCON ribbon connectors were disconnected individually for image and there was no half image even.
Later both ribbons were disconnected and TCON voltages were tested.
12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
There is also a short to ground in this circled inductor.
Is this a TCON issue or something else ?... -
Hi,
I have this problem with my Sony 55' AG9.
It flashes 4x.
I have found the service manual, and seems it is the TCON.
Before I buy a TCON can someone check the vid?
Thanks in advance!... -
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
