Re: where can i get electrical components???
the diode continuity is only in one way but the value is low.
i set the DMM on diode mode and those are the results..
look at the pic.
no im on diode mode.. look at the pic....Leave a comment:

Re: where can i get electrical components???
hey
sorry about the pics.. i will use the manage attachments from now on.
ok so i checked the diode on the board and the resultes are not good.
i know that i need to get 0.5-0.8 on a good diode and i get:
2 diode SR5150 give 370+/-
2 diode SB540 give me 150+/-
soo i guess those are not good.
so ill replace them tomorrow..
im right about the 0.5-0.8 value right???...Leave a comment:

Re: where can i get electrical components???
"what did you use for the GND REF point for the meter when you make that measurement?"
dont know what you mean...
i have like 6-7 diodes on the board. should i take them out for a check? all of them?
2 pics of front so you can see all components:
* the diode in red was taken out for a check and found good....Leave a comment:

Re: where can i get electrical components???
1. well in the showed side i get 0-190+- AC {gose up and gose down constantly}
and on the other side there is no value..
2. the monitor turn on then gose black after 3-2 sec. CCFL tested and looks good.
3. this is Hyundai x93w
4. this is the power supply board
