Samsung LCD/LED TV Model N0. UN32F4300AFXZP

[Andrew F. Ali]

Hi Techs and Friends.
I am looking for a Main Board for the TV in the name heading. The main Board No. is: BN94-06779U. This is a 2013 model and I can't seem to find this listed anywhere. Can you held me?
BTW the Power Board is good as I did a self-test and all voltages came up and the Backlights lit up also. This Main Board is loading down the StBy 5Vdc and causing it to fluctuate.

I own this model TV. I understand from Samsung that it is a model manufactured in Latin America. I have been trying to find out how to get it serviced as the TV cycles through powering on and off with no reason. I was told Samsung doesn't service these TVs in the US and I would have to send it to Latin America for service.

I would like to get the TV repaired or sell it to someone who is willing to purchase it with this known issue.

I welcome your feedback.

Do you know how to self-test the PSU?....If the self-test prove the PSU as good then the next choice is the Main Bd......I can't find any and there is no service information available. I may just have to give up on this TV. I can share the steps to self-test the PSU if you are interested. BTW how much will you sell it for?

Performed POWER BD 'self test' as follows:
1. Disconnect CNL802-jack to Back Light Unit.
2. Disconnect CNM803-jack to Main BD.
2. Connect a 1kOhm resistor across Pin 12-A5Vdc and Pin 14-PS
3. Connect another 1kOhm resistor across Pin 12-A5Vdc and Pin 6-BLU.
4. Re-install PSU BD with ALL screws in place
(Becareful not to short circuit any connections to each other and to chassis GND).
5. Re-connect CNL802-jack to Back Light Unit.
6. Apply 120Vac.
If PSU is working Back Lights will come ON and remain ON.
With the BLACK DMM lead attached to the chassis GND and
the RED DMM lead on the corresponding Pin Nos.
Measure (a) Pins 11 and 13-B5Vdc.
(b) Pins 1 and 3-13BVdc.

OK. So in desperation, as I was just about ready to give up, I typed in the Main Board No. and clicked search on BING. Lo and behold a supplier in the Caribbean 'noonbay.com' came up as having aboard available. Cost 55.00USD plus 20.00USD S&H. I gave them a try as I too am in the Caribbean. The delivery took about 14 days to arrive.
I slapped in the 'new' board and BAM!!!...The tv set came on and worked in an instant!!! I did not have to make any service or user adjustments. I went through the Menu and everything was perfect. Another one saved from the dump.

Cost 55.00USD plus 20.00USD S&H.

Wow, $75 USD for a main board is quite a lot for a 32 inch TV.

Now that you have a working and non working board, perhaps you can make non AC powered comparison multimeter measurements between the two to find your problem?

Thanks retiredcaps. I plan to do just that. 75.00USD is expensive but I closed my eyes and gave it a shot and came out OK...A moment of high influence here for me...I'll certainly try to learn this board...Regards
