I have purchased 2nd hand Samsung PS43E450A1W plasma with intermittent problem. According to seller TV is working and after some time it turns off or TV does not turn on at all.
Yesterday I have turned it on and TV was running for 5 - 6 hours without problem. This morning whenever I have plugged TV back to mains no stand by light.
So I have checked power supply and it is getting power. Checked connector to main board, there are PS_ON 3.7 V and connector to X-main have PS_On 3.7 V too. No other voltages. Power supply is BN44-00508B. Main board BN41-01785A BN94-05554K.
So I though main board is bad and disconnected it. Shorted PS_ON with the ground and nothing happens... TV does not give any life at all. No clicking as usual to Samsung TVs, no other voltages coming on.
From this point I am a bit struggling to understand what part is faulty.
I have attchaed some photos of the parts in TV.
