As the title says. i am having a hard time with this board. I can confirm it is the power board as I have two of these monitors and when I swap the power boards the monitor works.
I am not a pro with circuit boards by any stretch of the word but I can follow simple instructions well and i have decent knowledge on the use of multimeter and soldering. Please do bare with me when I ask "obvious" questions
Here are what I have tried so far based on searching this platform.
1. I have replaced all 3 resistors (RB805 -7)
2. I have replaced all the capacitors besides the main high voltage capacitor (CP803)
3. I have checked all 3 fuses and they are all ok
4. I checked the CP803 for Voltage when plugged in with the main power switch (next to the 110V input in the pack) and I get 168Vdc
5. I tried to measure the voltage on the connectors (CN801) and ground (I used LUG1 and LUG2). I got 0 Volts on all of them except S_B pin where I got 0.9Vdc.
6. I also measured the voltage on connector CN803 in a similar way as I did for connector CN801. I got 0 volts on all of the connectors.
So it seems i do not have 5V and 24V
I still do not have power not even the power button blue LED.
Any ides on what I can do next or what could be the problem. I really like the monitor and it will be a shame to toss it.
Thanks in advance for the help.
Cheers!!
