    I repair card detected rx470 but when I try furmark, pc goes off and get message from image. After second try card dead,ir3553 that I change dead again. Just to ask,card has 5x IR3553M, I used 4x because one is damaged pins on board. Can be reason less power to gpu to crash? Actually I used...

    On IN of UP0132P was 2v7, nowi removed ic and inject on output pure 1v8 Now without ic i see im to ice that is removed is 3v3 what should be. So i guess damaged UP0132P. Now furmark works and i see 1v8 consumption is 355mA and goes down when restart pc BUT suddenly instesd 1v8 i put 2v ir maybe...

    Hi Card not recognised not video out on monitor On board only 12v on 3-4 coils,5v,and 3v3, not any other voltage I resolder ic for 1v8 then all voltage present. I put card installed drivers and tested with furmark,was ok 61celsius max Today again no video out,and I noticed when put hotair on 1v8...

    I tried with 2 fases to test but no vcccore, I found no ENable pin to driver ir3567b,I bring 3v3 directly to EN pin and then vcc cire is 1.0v May I short 3v3 to Enable pin? Tnx

    All these 4 pins by datasheet ir3553 REFIN,IOUT,CSYN- and CSYN+ are connected to ground if current sens amplifier not used So maybe all to gnd Also i bring 0.7v to coil for gpu,and it draws 1A5

    I think as you says,maybe by heating i removed coating, but need help if someone has this card to check for me pins marked red and green,are they connected to GND First 2 pins from corner TNX

    All merged pins are so smooth like I dud with paper sand, not helping adding solder and flux,they are so flat like glued with sokder

    Yes china's amtech, that first pins are shorted to ground but from datasheet also can be both pins to gnd,if someone has this board to check for me Pins are csin- and csin+ Is ani chance to fix this,to scrach or what?

    I found 3th IR3553M from top caused short,now not short on 12v,but when measuring resistance on vcore coils to gnd its very low 0.6R Is that mean gpu also shorted,ir how to test I bring 0.7v on vcore coils and draw 900mA

    One tips works more easy to remove fets,I use solder paste on fet and can remove. Here us image where i gave shorts, 0.8R On vin pin of IR3553M is short,on top 4,botom is ok Is this meant all 4 chips bad??? Or those 4 top are in parallel, bottom one is ok,i guess it takes 12v from pci slot Smd...

    I have 2 hot-air stations One Atten 850A+ Other not know name,I put max temp,lcd shows 480c but with thermometer on multimeter shows 330c max that's why can't melt unleaded solder My job is car electronic and not had problem,but with laptops and graphic card must get better hot air station...

    I warm with heat gun from bottom, max temp from top side,I hardly removed 2 fets, it's crazy, pcb hot can't touch but part doesn't unsolder

    I did with alcohol, not any looks like hot , all VIn ang gnd are shorted,will have to do one by one. For this card there are 3 videos,same fises blown,one was controller (suspicions to me) on the left side of pcb,BUT as you told to me, I no idea how to desolder can't remove any parts,when i put...

    You mean to measures on top coil (it's through hole)marked yellow? To remove fets marked with red arrow,all 3? If you mean one of 5 phases fets are integrated inside,how can test? And yes on coil outputs is zero ohm,but I don't want to remove all 5 ior3553 but can see any mark on any of them...
