I'm still quite a newbie on monitors in my opinion. I can install a cap kit and even a HOT or flyback, however, it's just replacing parts. I want to be able to test using the schematics and replace the bad part, not all of them.
Although I have several questions, I'll keep it short. How can one test the power supply of any monitor? Let's take a WG U5000 for example. After reviewing the schematic, I see the a/c comes in at CN101. It goes through a choke (L101), some caps and resistors, then through a bridge diode (D101-D104) and that's where I get lost. I know that somewhere in there, I need to measure the b+, but where??
Next, if there is not a b+ voltage, then I should lift some component and hook up a load tester and then test the b+ to see if the power supply section is working correct?
I just need a little coaching here guys!
Thanks in advance.
