i didnt buy it. i got two broken iphones and took working part of each phone and made one working. so it is like for my own testing. i have read that with r-sim you must have this rsim with your own sim all the time. but it is cheaper than unlocking at apple server from someone on internet (6$...

nice to hear that. good work

i needed only solder and multimeter (lets say only ohm meter). i just only mesured fuses nearby lcd connector and i found one (maybe there could be more than one) fuse which i measured. ohm meter should say something nearby Zero 0 Ohms. when it says some big number limitting to infinity it is...

i could wait for an answer till the end of the universe. so i took my multimeter a found all fuses near display connector and started with measuring resistance. there were fuses F2, F10 which had some mili Ohms resistance. so they were OK. after that i found one fuse on the reverse side of the...

Hi guys, is here someone, who can advise me where exactly is a fuse on motherboard responsible for display backlight? I got one Lenovo T420 with black screen. When i plug external monitor, it works ok. when i shine on the display i recognize very dark desktop when laptop is running, so it has...

hello masters, is here someone (maybe with schematics) who can guide me to solve the problem with Fujitsu Siemens Amilo Si 2636 ? It doesnt even start up. i click on power button but nothing happens. It must be something wrong on motherboard MR030. What should i measure first?

on R252 i see 1.67 V DC

after an hour of searching i found R247 under a GPU board. I measured it and there was exact 3.3V DC. So signal to the fan is alright i suppose. So it means that it doesnt give any voltage to the fan. but what to do?

i am afraid i cannot find R247 resistor. where is it located? at least aproximatelly

ohh, thx for answers. i already cleaned the fan from all dust before i tried think about any other possibilities. you had very good idea about blowing into the fan so i generated about 0.5V with it so i think fan is ok. i dont have any battery to test it other way. maybe give some 1.5V batteries...

Hello masters, i have problem with notebook of my friend. Her Fujitsu Siemens Amilo Pi 2550 is not working. I dont know what is cause and consequence. When i turn it on, it shows booting and F2 for BIOS menu and after that next step it shows only black screen with white cursor. It is not about...
