Re: Samsung LN_S3251D LED Blinks Once
Just a follow up...
Since I wasn't able to fix the faulty board, I replaced the BN96-03833A (original) power board with a BN96-03057A (substitute). The set works fine now.

Re: Samsung LN_S3251D LED Blinks Once
I don't know if it matters, but when I plug it in I have no way of knowing if the set is on or off.Leave a comment:

Re: Samsung LN_S3251D LED Blinks Once
Okay, I changed batteries and tested #15 and it is still 6.04v. I checked it with a second multimeter and got the same results - 6.04v.
And to make sure I'm checking this correctly... I have the tv plugged in, the ribbon cable disconnected from the mainboard and I'm checking at that connector end (the other end is still connected to the power board)....Last edited by Jim8181; 03-28-2013, 04:29 AM.Leave a comment:

Re: Samsung LN_S3251D LED Blinks Once
All of the pins except #1 and #15 are 0.0v.
Pin #1 is 0.1v and pin #15 is 6.04v.Leave a comment:

Re: Samsung LN_S3251D LED Blinks Once
This connector that says 12v, grd, 5v, 5v, ect? The one with whites and 2 blues?
Whats pin #1? TV plug in? Connector off at main board? Check voltages at the connector?
Hope those questions make sense....Last edited by Jim8181; 03-27-2013, 05:24 PM.Leave a comment:

Re: Samsung LN_S3251D LED Blinks Once
From the power board to the main board I have a 5 pin ribbon cable and a 16.
One of those 2?Leave a comment:

Samsung LN_S3251D LED Blinks Once
I have a 32" Samsung Model LN-S3251D. It flashes the LED once when I plug it in. That's it.
It appears to have a power board that is not common (at least I can't find much on it). Power board number is BN96-03833A.
Non of the caps "looked" bad, but I went ahead and ordered a cap kit that was for a similar board. I replaced 11 of the 14 caps and nothing changed. I'm picking up the 3 remaining capacitors tomorrow.
2 fuses check good.
Any help will be appreciated....
