in mobile phons me jo component lagaye jate hai wo  ek hi tarah ke lagaye jate bas inka section change ho jata in component me main yaha par apko kuch ke naam batta raha hu jaise

POWER IC  –   RTC – (REAL-TIME CLOCK)  POWER MANAGEMENT  IC –  COMBO MEMORY IC –  CPU –  RF IC –  RF CYSTAL – AUDIO AMP IC –  BATTERY CONNECTOR  BLUETOOTH DRIVER IC –  FEM – MMC BUFFER IC – SYSTEM CONNECTOR – BACKLIGHT IC – SMD RESISTER – COIL –

inke alawa bhi mobile phone board me micro type component lagaye jate hai

Automatic power on/off  fault

mobile phone se  connect karte hi set power on ho jata hai  mobile phone switch ko short ya  kharab hone ke liye chack kare  mobile phone power switch ko kharab hone par change kare ya CTC se clean kare

check kare kahi charger connector ki pin apas me short to nahi ho rahi hai  charger connector ko remove kr ke dekhe   mobile phone IC ko short ho jane ke liye check kare

NOTE :  power on/off fault  mostly occur when  positive pin of key connect with ground

Automatic power on/off  fault  mobile phone power on key  ki  positive pin ya  line ground sire se  connect ho jane  ke karan hota hai

damage hone par replase kare  battery lagakr  power on key par  3-3.6 volt check kare  mobile phone key par volt na ane par ya

kam ane par   mobile board ko CTC se clean kare or  low  heat de  power key signal  filter  ke defected  hone par use resold kare ya

badle  mobile key signal filter ke  connect sire par  bhi power on volt 3.6 nahi ane par  power IC ko resold kare ya chenge kare

NOTE: set automatically  power on while battery inserting  then check power switch  power on signal filter and power ic

POWER  ON  FAULTsoftware se connect karke  normal mode select karne par  mobile on ho raha hai  lekin battery lagane par mobile on nahi ho raha hai

iske liye sabse pahle battery ko change kare  battery  connector BSI pin ke  connection check kare  agar ye thik hai to  BSI pin par

maan check kare maan na prapt hone par  track ke open ho jane ke liye check kare or jumper lagaye

LCD connector or hands free connector ke connection ko short hone ke liye check kare  agar ye sare component sahi hai or track

bhi kahi se open nahi hai to  power IC ko resold kare ya change kare   ya CPU  ko  resold ya change kare

mobile phone ear speaker ko change kare    ear speaker ki line me lage component ko shorting ke liye check kare

power IC ko resold kare ya  change kare

MULTIMETER SE CHECK  KARNE PAR  MAAN  THIK  AA RAHA HAI FIR BHI  MOBILE PHONE  ON NAHI  HO RAHA HAI

multimeter se check karne par  battery connector tip par maan .260 se 300 ke ass pass aa raha hai  lekin fir bhi mobile phone on nahi ho raha hai

AC/DC  machine se set on nahi ho raha hai  wa machine me current adhik lene ke sath  sath  shorting bhi aa rahi hai   or set on karne par  power IC heat ho rahi hai

to PCB board ko CTC se achhi tarah se clean kare  or power IC ko reball kare ya change kare  yaha fault power IC ke output section me shorting ke karan hota hai

output section me shorting  check karne ke liye  power IC ke pass lagaye gaye components ko  check kare

so friends aapko ye jankari kaisi lagi hame comment kr ke jaroor bataye our aapko mobile phone repairing ke bare me kuch puchna hai to hamare se comment ke jariye puch sakte ho  or is  jankari ko facebook twitter par jaroor share kare
