I am new to tv repairs and want to get serious making it a full time thing. I have looked at about 14 tvs for a company and have managed to repair about 5 which is not a good ratio in my mind but i am new to it. I am running into many problems as in running into parts which dont even seem to come up on google such as diode 1k4 jf . In circuit it seems shorted but out of it it shows voltage drop of .147 and just wanted to see a data sheet so if anything i can find an equivalent . Another thing i have bought some basic things like multi meter, solder iron, esr meter , heat gun , and small things like screw drivers and what not but i want to know what is recommended as far as an oscilloscope and would i need to invest in a lcr meter ? alot of these power boards i feel like i have tested every component ecept the transformers and inductors but i still get a 0 v output even when i short the pson with the 5 v so out of frustration wondering if there is better way to test out the mosfets besides checking for shorts with multi and equipment for testing out the transformers and inductors. What am i missing here , it can be really fun but at times seems extremely frustrating. I have basic knowledge on electronics , I am studying electrical engineering but doing this on the side to help pay for school and only have 2 semesters left. I started with laptops , desktops , and cellphones but i see greater profit in tvs since some tvs i have fixed for a mere 3 dollars . Thanks for the input and thanks to anyone with valued advice.
