My monitor decided to die overnight,

I can get it to very dimly( is that a word?) flash logo's and part of the boot sequence but that's all it will do.
Googling came up with a possible cap problem on the psu, as I haven't the time or inclination to open it up and find out if it is the problem then source the capacitors then solder them in
the question is, How much would someone charge to replace the capacitors/repair the monitor?
