Sony Xperia XA1 Ultra Charging Problem Solution

April 13, 2023

Sony Xperia XA1 Ultra Not Charging! Case: Mobile phone works well, there is no problem if battery has charge on it. When I connect it to charger which shows current drawing on charge, there was no current drawing on charge. (first line and second value is zero althought it connects to mobile.) Solution: Let's Measure Some Points! First point is 5v Vbus from charger station, there was 5v. This means our connector, and flex are good. This point goes to OVP IC (Over Voltage Protection IC), there is an input capacitor, this point also has 5V. The second capacitor placed upperside of OVP is output capacitor of OVP circuit. There should be 5V if OVP is also good. But there is no voltage on this point ! This can be caused by damaged OVP or any short on output line, when I measure short circuit on this capacitor, no faulty, It means OVP is damaged. Solution is Changing OVP IC by new one! or another aspirine solution ( I never recommend this but it's a solution too ) You can short i

iPhone 7 Plus Speaker Greyed-Out Audio Problem (Solved)

April 20, 2023

iPhone 7 Plus Audio Problem Speaker Icon Passive (grayed-Out) on Calls Case : There is no sound on calls, Voice Recorder doesn't record anything, Speaker Icon on calls is greyed-out. Solution : This issue generally (for iPhone 7 and iPhone 7 Plus) occurs when Audio Ic damaged or has broken lines/pads under the chip. I have experienced this issue because of bad front camera flex several times also. Removing Audio IC: Remove the Audio IC, and remove soldermask on lines with a sharp and thin knife carefully like image below. and solder very thin copper cable along lines to the pads, then apply solder mask on the lines (not pads) line on image below: keep main board under the UV light (to get to ready solder mask) for about ten mins, so you can install the same audio ic back. Result :

Iphone 7 Charging Problem Solution (Done)

April 19, 2023

Apple Iphone 7 Not Charging! Case : Apple Iphone 7 not charging, nothing happens when connect the charger and just 1mA current drive on USB charging cable power line. Phone works well with a charged battery, also there is no effect when phone is powered on and charger plugged. Expected behaviour of the when the battery not connected and charger connected is valid voltage generated on VDD_MAIN line (about 4v) and boot loop on the screen about 6-7 sec. periods, and current drawing 17mA, 50mA, 110mA, 200mA and zero respectively. This issue can be caused by the charging flex, but changing charging flex resulted the same symthoms. Not charging, no current draw! Second suspecious part(s) are the parts placed arround charge flex b2b connector on board or itself of the connector, and there was no problems at all. The classical hero is that kind of problem is generally Tristar IC known as U2 : 610A3B Our hero is buttom side of the iphone 7 logic board (below NAND Memory). But there is a little
