Re: Sony Bravia KDL-46V4100 power off itself
So it comes on then goes back to just standby voltage

Re: Sony Bravia KDL-46V4100 power off itself
I didn't think it was a bad panel or drawing too much current because it does the same cycle with relays clicking on and then off even with just main board and power connected. Unless it exhibits the shutdown behavior if everything isnt connected?Comment

You should have a connector for backlights and probably a bl_on terminal. No pictures I assume this is fluorescent backlightsI assume no responsibility for any stupid suggestions I might post.Comment

Why would
52V4100 and 46V4100
Have different main boards? The part numbers are only off by one digit?Comment

Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
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!...
