Hi Guys ,
Hope you are all staying safe and well in these troubling times
I need some help please on the following fault condition
Samsung Plasma panel is showing a red standby light when i switch it on via the remote it clicks the red light starts flashing then goes to white led but no picture or sound is displayed ,
I have checked the voltages here are my results
BOARD NUMBER BN44-0044.7A
Mains power 230vac
VS = 0V
VE= 0V
VSC =0V
5Vstby =5v
So i have a issue with the supply board not turning on
so i have checked the pin header connections as follows
Bottom header 6 pin CN602
B5v=5vdc
B5v=5vdc
Gnd=0v
VScon= 0.8vmv
PSon= 206.2mv
VSon= 1.7mv
Con 601
B5v=5.63vdc
B15v=15.7vdc
B15v=15.7vdc
GND=0v
GND=0v
GND=0v
B15v=15.16v
GND=0v
A5v=5.379vdc
PSon=209.2mv
So i had access to swaping out a power supply board with a verified working one
the fault still remains , i believe it might be a fault in the Main board not switching on the power supply
Is their a way i can jump the connector to manually turn on the supply board to test if it will come on?
your help is much appreciated
thankyou
Wayne
