Hi,
When I connect my samsung LCD ,the image appears at first and a few seconds later the luminosity drop and the image become so dark we hardly can see it, but the image is still there. So I first tought that the power supply is broken. Also the transfo on the power supply board emits a sound as if there was a shorcut in it;as if it was making electric arc inside.
As the transformer seemed the most suspicious and since I couldn't find the same transfo anywhere I ordered a new power supply.
Now, when I try it again, it does the very same thing.The transfo emits that same sound , the monitor turns on for a few minutes and then the luminosity drops and we can't see anything.
So I remembered that the power supply I bought on ebay was used , but supposedly fully fonctionnal.
My question is: Is it that the power supply I bought have the same problem as the last one, or could it be a problem somewhere else in the monitor?
Because if it is a problem somewhere else I really can't see why would the transfo make that sound. What is other typical problem that a backlight can have if we supposed it is correctly powered?
Thanks!
I will return the boeard to you, can you pay the shipping and send me another one?
Thank you for your fast answer
