Technomate TM-TWIN-OE burned IC SD4841P 67k65yw3j0fz , equivalent IC required

Each driver ic works on specific configuration such as frequency, transformer windings and other related feedback Circuit.

The ic, which is burned works in 65Khz frequency and 1:1 p:s transformer winding. The pinout is also different than the mentioned power integration ics.

This, it is not possible to use other ics.

You can purchase the ic from alibaba or other Chinese sources. Do not use other ics since it will be dengarous.

Hi guys.
Good news, the IC SD4841P was replaced on the mother power supply board.
Bad news, when I unscrewed the power supply board, I saw other burned area, as you can see in the pic I send in this email.
The worse scenario, I have searched in Google “B TSFM 10100 10C” and …nothing comparing with the other burned IC SD4841P that I have found suppliers on Ebay. So I do not know what component to search.
That area it belongs to the D3 , on the component is wrote: B TSFM 10100 10C as you can see in the pic attached.

Diagnosis: I have picture on the TV, the “OPENPLI”, but in the receiver, the display does not work, the remote control does not work, the buttons in the front panel does not work.
I have to power off from the back side of the device( the I/0 button).
I can hear the Hard Disk Drive(HDD) spinning , and also the fan.

So basically I do not know the component type to search it , I do not know the manufacturer, the "B" letter printed on the component is not helping a lot in this situation....
So I hope with all my heart someone knows.
Waiting your reply, anything could be helpful.
Thanks in advance.
