Hi guys new to the forum so please be gentle,
I have a Dell U3011t monitor which has a supply problem from what I can see, monitor switches on ok but after 5 mins it switches of and can not be turned back on without removing power and then powering back up of which the same thing happens again.
I stripped down the outer casing and had a good look and tested voltages which shows the circuit to run at 30v, this is all good but as said after five mins circuit shuts down and voltage is lost.
A bit more investigating and found one of the heat sinks getting very hot so put a fan blowing cold air over it and the monitor stays on, also there is a slight amount of heat generated burn around the transistor area so have removed the K10A60D Transistor nearest to the burning and have tested it and as far as I can see this is the problem.
Anyway I am now looking for this part and am having problems because I am not 100% sure what it is called, also apart from the K100A60D marking there is another marking of 2:E of which I am not sure when ordering would make a difference or not.
Any help would be much appreciated, also the best pace to order the part from
