Help with a switchmode PSU?

[things]

Hi, I have a +/- 15V DC switchmode power supply here. A few days ago, I came out to see it smoking!! The LED's were all going fine, so I thought it might just have been overheating. Upon testing it, I get about 11V between
V1 and ground, but I get nothing between V2 and ground. the LED comes on, and theres no smoking, but there is a few capacitors/coils etc that get quite hot quickly. Any idea's?

Thanks
