Re: Sony KDL-46EX400 2 blink error code
From my little experience:
In a fully working Sony LCD/TV set
I've seen BL_ERR is set to HI (3.3v) and BL_ON is set LO in standby mode. It's just normal. And the situation is reversed when the set is on.
So BL_ERR and BL_ON are just used as triggers of the lamps and not necessarily to indicate real errors.
I'm sure this info can be backed by the more seasoned members of the forum.
P.S. I can't understand why this simple thing has not been said by the many, many people that have answered to your questio...

Did it apply to the SMD soldering too?Leave a comment:

Re: LCD TV Power Supply 12V Testing
The board don't have that markings.
What I've been wanting to do is to prove that the 12V out of the PSU is fully working. That cause I have the proper voltages but the TV doesn't work.
If somebody can see, here is my complete history:

Re: LCD TV Power Supply 12V Testing
Where did you see the 3.5A marking?
My TV is 40" and I can't see what is the maximum current.
I didn't find the datasheet of the regulators.Leave a comment:

Re: Sony no image, no sound and no standby flashes
I found that schematics of KDL-40EX500, KDL-40EX400 or KDL-32EX302 are similar to my KDL-40EX407Leave a comment:

Re: Sony no image, no sound and no standby flashes
I reconnected everything and tested it:
The result is "no relay-click sounds" and the voltages as I said before, that is STBY,ACOFFDET,PWRON,BL-ERR=3.3V
BL-ON,DIMMER,TCON-ON=0V
12V and 24V are fineLeave a comment:

LCD TV Power Supply 12V Testing
¿How can I load to test the 12V on an LCD TV PSU?
The voltage is ok with a minimal load (a car break bulb) of 1.75A
But I want to know how much current can I get to know the PSU is really ok. -
Sony no image, no sound and no standby flashes
Well, for all the LCD TV Repairing masters.
I've a LCD TV with the following symptoms:
- No StandBy flashes, just Green Power Led steady as normal
- No image, no backlight and No Sound. Even by changing input, volume, channels. Even by trying to enter service mode or whatever
- I isolated the PSU and tested it and it gives all the voltages
- Also, I isolated the Inverter and just by connecting it with the PSU it works properly illuminating the lamps
By measuring I've found:
- BL-ON, TCON-ON, DIMMER are 0V
- BL-ERR is... -
