Re: Sony kdl-46ex723 blinks red 3 times
ok so I downloaded this and it said 3 blink was either dc alert or audio abnormal detection, so I unplugged the speakers and still got the code? so I figured it was the dc alert, so I was testing the 3.3 volt standby and accidently touched the prong next to it and that one together now im getting a 2 blink code and I cant download the manual again so I don't know what the 2 blink code is and now I don't know what to do?Comment

Hello,
I have a Samsung DM32D display.
When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.
Here’s what I have tried so far:- Disconnected the cable between the mainboard and the power supply → the backlight turns on.
- Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
- Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.
From these tests, I suspect the problem might be on the mainboard. Could anyone...08-24-2025, 03:47 AM -
Hi,
I have this tv that works for about 15 to 20 minutes and then turns off, leaving the led to blink 8 times, this via HDMI, because I can't get into the tuning menu, it says Function unavailable.
Through the manual, I was able to verify that it could be a software problem, but unfortunately the tv already has the latest software and that's why it won't let me update.
Does anyone know of a way to reinstall the software? -
Hello,
I have problem with SONY 55X90J. After several check status is as below;
1. Running power board as stand alone:
TCON_12V =~ 12.6V
EVDD V On Max 24V= 19V.
2.Running power board with TCON as stand alone:
Effect as below, attched.
3. When bottom LVDS cable is disconnected no blinks, but of course no TCON 12V and EVDD.
"I'm almost sure it's a defective panel, but maybe someone has encountered a similar issue on their screen.
Best regards.... -
Hi everyone. First post on Badcaps!
I am trying to fix a Sony 940E from 2017 that either starts normally (and works perfectly until turned off) or goes straight to the 6 blinks error code without showing anything on the screen. It is frustrating to know that it can still work perfectly but is barely usable because of the difficulty starting it up. I am willing to try to short the BL_ERR but I would like to avoid that if possible. Does anyone have a view on this? Thanks a lot.... -
Hi,
I'm working on a HP Victus that is not turning on. When power button pressed it only blinks 3 times with charging led. I have checked input mosfets and they are fine. Also all coils are fine too. Battery was empty but I charged it with my lab PSU and laptop started on batery but is not charging. When battery is disconected and only PSU connected it takes 0 current and not starting. What can be the reason?
