hi , agree with bighead .

thanks for the reply / resistance between 17/18 is 3.0 ohms and 27/28 is 20.6 BUT r7005 was 166 ohms so removed and replaced with another resistor and now green light is coming every time i plug in the charger but the PPBUS_G3H is fluctuating quicker between 3.96 volts and 4.15 volts .

hey guys , another crazy one to share for advise . problem =PPBUS_G3H is moving between 2.5 volts to 4 volts . i have checked thoroughly for liquid damage but could not find anything may be under smc but no traces of liquid outside any where . i do get green...

hi duke , i checked the external , internal , everything . after all that then went and did reflow ( only with hot air and flux for abt 30 -40 secs) Before and after same result ( the system is working without display) Also i have mentioned above no display on lcd or external :D:D:D

hey guys , received this board dead as it was liquid damaged, managed to bring it back to life but no display is there . 1. there is no image ( no PPVOUT_S0_LCDBKLT) 2. w/ screen PIN 4 = 3.2v PIN 6 = 3.2v PIN 7 = 3.2v 3. q9807 no voltage on pin 5 4. 1.57 volts on c9560 i...

hey guys, got the cp500d delivered today , now waiting for es132 . kindly advise on usage and do's and dont's thanks

thanks for the information guys. take care

hi , please advise if anyone has used the smc's available on ali . are they any good or are they blank . i remember Louise mentioning the trouble of removing them from donor boards and reballing and hoping it was a good smc . thanks

hi , look for ezp programmer on ebay . will get the job done

HI , currently using work tracer , affordable and has got lots of features. lacks a bit in stock inventory but does the job .

hi , thanks for the response , i have just checked the schema , you are absolutely right , there is no ground to it , it is connected to the resisitors and q7800 , actually every time it stops working the c7800 shows continuity like a fuse as it was a caps so i didn't bother and thought it was...

hi guys, received the board with c7800 short to ground , removed it and replaced with a good one and it worked fine for few hours the it goes bad again , this has happened few times , can you suggest what can that be ? i will update about the voltages on it later. thanks

hi, that board went away but i am replacing the smc on 820-2838-a, i have removed it successfully but now i am unsure that either an smc taken from 820-2327 will work on 820-2838-a i or will not work ? logically the new smc's can be programmed differently so no idea. Also i...

without a doubt :cool:

thanks for the response , q7030 kept on getting hot , this time rather than replacing q7030 first i replaced the isl and then replaced the q7030 , now it is not getting hot but now on battery plugged in i was getting very low output from d6990) and after replacing d6990 i have 3.42...

hi, there are few things to check first 1. Do you have 3.3 volts on power button , (please press and check if the voltage drops) if you have then 3v 5v regulator is most likely working . if you do not have then you need to check the 3v 5v regulator . 2. In case you have the...

hi Aprendiz and Louis , Thanks for the update and information , it came from another repair shop , i am attaching some pics , please have a look , i think on Q7030 the voltage should drop to 12.6 v but it does not drop and stays between 17...

hi , thanks for the reply , Q7030 is getting hot without the battery . i will check the voltages and update thanks

Hi guys , need help on this board . it is running fine on the charger but does not detect battery , i have checked the resisitor r5281 and r5280 , the both are showing 2.0k there is no short to gnd on SMBUS_SMC_BSA_SCL and SMBUS_SMC_BSA_SDA. i have already changed the isl but no change . the...
