Need help with an lg os-5020 it stopped working(fixed)
« on: March 14, 2016, 05:47:08 pm »
Hello, so i was using the scope and it was working well, then i switched it off and disconnected the probes, after a while i turned it on, with no probes, and when i hit the switch i heard a pop and now the controls dont work at all
here's a picture of how the screen looks like

i tested the fuse and its allright
i opened the scope and i cant find any burnt component
what can i do?

Solved! new record
its the resistor r353, its 2.2 ohm, it was burned, just replace it in case you have the same problem

But you didn't see if the new resistor isn't too hot? It can do the same problem...
Thank You, for all earth.

no, i leaved it working for an hour and nothing, keeps cold, the new resistor is 2w the old one was 1/2 a watt

Ok but, look at the function of this resistor,maybe a big resistor can't be so good as you think,
put 1/2 watt as the original.
Thank You, for all earth.
