Hi Pete, thank you, XXXXX XXXXX provide you with the schematic and board view file can you help me locate the VReg5 device connected to the TP51125 Power IC?, thank you, XXXXX XXXXX forward to hearing from you.
Hi, Peter I emailed 2 emails the schematic and board view files to you, I put Attn:Customer thanks please if you can help me, I would be much gracious.
The board view files wont go because justanswer thinks they are viruses, is there any way I can get them to you?
Ok, I will do that shortly, thank you
Hi, here is the rapidshare links:
what do you suggest?, should I lift device U7200, then apply flux and new solder?
No it didn't work, should I buy and replace the U7200 device?
Parts came in today, I am going to test them
Hi Pete, thanks alot!, I replacd the power ic, and the reg5 and reg3 readings are back up, but it still won't power on. I went to the transistor connector to reg5 Q7220, check it out in the board view file, aat pin #1 og Q722o, I get 0.05v as my reading instand of 3.3v, what do you think?, is something elses dragging it down or is that transistor faulty, at pin numbers 2,3,and 4 I get 12v readings, please give me your thoughts and what should be done next. thanks
Yes, the board should be completely removed from any power source.Let me know which multimeter you have so I can check if it is capable of carrying out this test?
I am going out now for a few hours so will catch up later...
I testEd the component I got back no reading or responsI'm would this mean that the component is defective?, I get 1 which is the default number the meter starts with, do you think the fet is defective?
I think I messed up the logic board even more, I accidently touched the board while it was plugged in. Now the TPS51125 power ic only gives me the reg3 (3.27 Volts) and reg5 gives me (4.99Volts) when I plug in the battery, it doesn't show any signs of life off of charger power. Please let me know which component may have failed, thanks
