Hello to all of you in this forum. I have found so many useful things here, from various info to excellent tutorials that helped a newbie like me to fix some simple electronics..
So, first of all, let me express my gratitude to this forum and all its members.
I am in NO WAY an electronics expert (not even studied any stuff like this). But many times i have stumbled upon "broken" electronics that need fixing (like replacing some tact-switches in my synthesizer, replacing capacitors, resistors, or constructing a pcb with various components based on other peoples' instructions etc..)
So, now, a new problem arised : my plasma tv has gone black, and based on various stuff i read in the web, it would probably be the YSUS boards' fault.. So i tried to check some electronics components with a multimeter, and found some transistors shorted to ground, and maybe a PP capacitor is leaking ...
Unfortunately, the transistors have some markings i cannot translate to actual specification, and i really need your help in this. There you go:
(transistors with 3 legs THROUGH-HOLE, probably TO-220 or TO-220F packaging, if i say this correctly..):
1) (1rst line) 0944 / (2nd line) F20LC30
2) 1942 / F20LC30
3) 0544/ F20LC30
4) 0644/ F20LC30
(Transistor SMD with 3 legs (one not to be soldered) and a tab on the opposite side) :
N 4C / 61FC4
I really do NOT have a clue if these are MOSFETs or diodes or regulators. I only found datasheets for the F20LC30 but i cannot identify the numbers before this code, so i am not sure if i should buy any F20LC30 with different numbers..
I would greatly appreciate your help with this.. (please note that my electronics knowledge is quite limited, so be gentle
