You didnt try to DIY?

If your monitor has display problem like ghosting, polariser peeling then dont waste time fixing. However if there's just power supply issue, it could be an easy fix. I fixed a couple of office old LCD monitors just by replacing a bloated capacitor on the power supply board that only cost 1-2 ringgit.

Just dismantle and see lor... mine all the old type, using psu type connector, hence power supply board inside the monitor. Not sure about yours. I also got one samsung spoilt monitor which I threw away because the capacitor cost like RM60 when I googled. The other that I fixed are mostly LG which uses cheapo smaller value capacitor.
