Help choosing replacement SMD transistor
Hi there everyone,
Im looking for a replacement transistor for my TV's logic board, unfortunately i had a newbie slip and shorted out the Pwr_On to the 20v rail with the mainboard connected, not very clever at all i know. Here is the damage.
Transistor Close up
Original Transistor Datasheet : RT1P141C Marked P1
Main Board Schematic for transistor Reference: Service Manual / Main board Schematic Not the exact same model but im pretty sure they use the same transistors marked P1 which is the RT1P141C.
My other question is could i still be lucky enough that this hasnt damaged anything else ? After the component got burnt i could test continuity on all 3 legs...
I have another thread which i specifically made for diagnosing my power supply on my LG set, i hope creating this thread shouldnt be a problem as its more aimed toward finding a replacement than diagnosing the mainboard. im quite desperate for help sourcing this replacement transistor as i might even have to import it.
I guess choosing a replacement with small differences shouldnt end up being a problem although this also depends on how close to the limits this transistor was being used in the first place ? Please correct me if im wrong.
If anybody has detail into what specifications are utmost important in choosing a replacement transistor id appreciate it. Thank you all !
