I have an old Compaq TFT5030 LCD that won't turn on. Dead when hitting the button.
Heres what I have found. You'll notice in the pic 2 red circles and a blue line between them. The lower red circle is a fuse - it's blown. The blue line follows a trace up to a regulator numbered SK 8033JD (data sheet http://pdf1.alldatasheet.com/datashe...SI-8033JD.html ).
The 8033JD pins measure as follows 12.33V, 6.94V, 0, 6.88V, 2.428V
According to the data sheet, the output should be 3.3V, not over 6V.
Let me know if I'm correct on this, but it appears this regulator is double the output it should be and it blew the small fuse.
If I'm right, where can I find this regulator? I can't find a cross at digikey. If I'm wrong, let me know where I went wrong! And what should I do next!
Thanks as always!!

(This is such an old 15" monitor, don't know why I just don't toss it! But I can't help myself, I just have to fix the darn thing! What's wrong with me....)
