Ps2 Slim V14 & Matrix infinity no power :(

[cronogr]

So here is my problem, recently i bought a slim v14 ps2, 4 days ago i mod it with a matrix infinity & and the laser fix (never played before the mod) all went well no problem at the installation i flash the chip and all was allright i was able to play any game etc. Until yesterday, when i press the power button nothing happen i tryed everything i could even check the power supply with a multimeter, anyway i open again the ps2 and i doublecheck all the connections i read some similar posts at this forum and i try all the staff i found but the problem remains, my ps2 refuse to power up.
Tommorow i'm going to remove the chip and try to see if the ps2 works without it hopping to make it :/

W8ing for your advices

edit: I can post images if you want from the mobo

if the power supply is reading right, then it sounds like a fuse, check all fuses on motherboard before removing chip,
cheers
