thank you very much without datasheet or more information about it it will be quite creasy situation
then to find the right stencil for it wont be easy i will search on YouTube maybe i find some indications how to fix it but do you have an idea how much hot can i use to not destroy the chip
my IRDA T-862++ have 350 c degrees max .
I have already removed an SD from a broken circuit but it wasn't perfect because I think I used low heat on preheating only 160 degrees and 300 on infra red will try with some others to find the right temperature on the real chips...Leave a comment:

I have an IRDA T-862++SMD BGA REWORK STATION that can be used even if i am not very familiar with it i am training on other chip to learn using it. why there is no datasheet of that IC Chip?...Leave a comment:

Yes you are absolutely right it is BN94-16627'N...Leave a comment:

Tank you Diah and you think there will not be any problem of computability with even ones? .This Mainboard i maybe should rework it but i do not find any datasheet for the chip :SDP19405 i do not know the size of the tin boll on it.
it is the one you helped me in an other thread with the same TV number for 2or 3 days ago the owner want to try an other Mainboard but i will try to rework the old one anyhow.
Thank you again Maestro...Last edited by bohaboha; 01-19-2025, 03:15 PM.Leave a comment:

Help Me Choose the Right MAINBOARD
It applies to Mainboard BN41-02751B-000 for Samsung UE70TU6905
this is what is on stick : HU10 BN94-18627N P09R
010233092557 0062 2021023
1465.4-143/1010

There are several part on Ebay for 55,65 and 70 TV but the number on the Stick label is not quite correct I am very unsure if they fit or even if they are somehow compatible with my unit. Very very grateful for any help -
You really encourage People to try .just fantastic...Leave a comment:

yes i it is .it hapen that i have this IRDA SMD And BGA Rework Station T-862++ i am thinking to use to just reflow the chip but i believe i will need a good liquid flux that i do not have it now to help the situation if you know wish one i should take ? i have already solder paste 01 but i think a liquid one will be better...

[QUOTE=Diah;n3547547]stack on STBY , this is different status as the Title you stared the threat.... what did you done wrong to make the set didn't start??[/QUOTE
nothing special just try t take away the black heatsink that was a bit hard to do[QUOTE=Diah;n3547547]stack on STBY , this is different status as the Title you stared the threat.... what did you done wrong to make the set didn't start??[/QUOTE

Doing this test suggested by apokalipto to activate pmic voltages shorting trdy1&3 test points did not change anything in tv behaviour always stack on STBY and nothing happens on screen
here some pics mainboard without heatsink i do not find datasheet of this SDP19405...Leave a comment:

No Diah nothing displayed. yes am asking because none of the code is working it seems the TV freeze on STBY
however the 12v,3.3v and 5 volt are present on the Tcon part of the board and that 5v you wanted on pin 7 is there on pin 12 instead of pin 7 but no 3.v on the lvds
i do not understand why there is 180v and 190v on the cold side of the power supply...Last edited by bohaboha; 01-12-2025, 06:02 PM.Leave a comment:

When I press on on the RC STBY goes out and returns directly in the same position as if it can't start the TV so the RC works.
I have managed to get rid of the black heatsink.
thanks for the chart but it's not exactly the same because on my kontact pin 6,16,19 and 20 are free(not used) plus I only have a start button...Last edited by bohaboha; 01-10-2025, 07:40 AM.Leave a comment:
