Mr
I received a Samsung Plasma TV that does not turn on but a sound is heard when connecting to the 110 VAC socket
By disconnecting the x-sus, y-sus, and main boar cards, I determined that the SPMS was delivering the correct voltages.
By connecting only the Xsus, Vs stays at 208V
Connecting the Xsus and Ysus drops the Vs voltage from 208 V to 10 V
connecting the main board alone the voltage Vs drops below what is indicated on the label 208 V to 10V
connecting the X-sus and the main board also drops VS to 10 V
I found some bad diodes and IGBTs, already identified from other posts in this and other forums.
but I still need to identify the D5000 diode that gives continuous in both directions is from a Y-sus board of Samsung plasma TV PL43E4000U1F, Y-Sus card LJ41-10281A LJ9201897 very similar to LJ41-10136A
sorry for any error, I use a translator to communicate
I appreciate your help
