Hello, I am having problem with this Samsung ps43d450 plasma, the problem is that the relay when on load keeps clicking off and on, at the time the vs voltage will go off and on. I have even tried to use a 200watts bulb as a load. I need help please
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: samsumg plasma PS43D450 PSU ISSUE
How much voltage do you get on the Vs line? Just saying it goes off and on does'nt help much. What is the BN44-00xxx number ?
What is the voltage across the main filter cap, in standby and when you force the power supply ON (does the voltage increase when ON?)Last edited by R_J; 03-06-2020, 04:04 PM.
