- g´day! I have a samsung 22" tv monitor to fix. power supply model bn44-00505A. some stuff blown up on the primary, according to research something typical on this model. secondary seems ok. writings on the board say in outputs a5v (standby), b5v (switched) both on the lower 3 diodes on the picture, vamp and b13v (12.8v, both are the linked at the connector that goes to the main board) my question is, are both the upper diodes for 13v? I believe so but wanted to make sure before injecting voltage there to test. I injected 5v on the lower side and standby circuit is working fine
- if I understand it correctly both 13v volt rails are just separated because one goes directly to the backlight coil and the other goes whatever (I assume the mainboard for tuner and stuff)?
- if both upper diodes are for 13v rails I will just modify some power supply I already have instead of spending money and time waiting for the components since the device is not worth much to begin with
- PS: by typical for this model I mean the ceramic cap (cm804), the controller, the bridge and the fuse
- Thanks in advance
