Repairing LCD Monitor Samsung 943NW

Today we have repaired the Samsung LCD monitor with model no: 943NW , he come with symptoms that monitor off after 2 seconds.

I opened it and saw that the electrolyte (100uF/400v) cracked, then I replaced the new capacitor, but the problem is still here, the monitor turns off after 2 seconds, I tried the other new CCFL lamps but now shuts down after 30 sec, in that period as the monitor for i felt that the inverter transformer smell the melted plastic. the original transformer was TMS92903CT replaced him with a new inverter  transformer TMS91429CT and I solved the problem.

    is it a difference between “TMS91429CT – K07TM24A” and other  TMS91429CTs? because i want to replace mine with another  TMS91429CT . I have a samsung 19′ 940n.

    I think they are the same .. but first check the resistance on the transformer and compared the two of them (think of your transformer and in this video)
