MB- R23 PROBLEM- DEAD. TESTING & SOLUTION- FIRST CHECKED VIN. 2nd MOSFET K GATE PE 0V THA. 28V KI IC CHECK KI. USKI REQUIREMENT OK THI, AUR 28 GENERATE KR RHI THI, AB CHARGING IC KO CHECK KIYA TO ACIN KI PIN PE 100K KA RESISTOR JISKE INPUT PE ACIN 3.3V THA MGR OUPUT PE NAHI THA, 28V IC KI POWERGOOD PIN JISPE ACIN AATA HAI USKO DISCONNECT KIYA, VIN OK BOARD ON HONE LAGA. MAGAR NO DISPLAY. CPU HATANE PE PLT FLACTUATE, AUR CPU LAGANE PE KABHI PLT NHI BAN RHI, KABHI BAN RAHI, AUR KABHI FCH K AASPAAS TOUCH KRNE PE DISPLAY AAJATA, FCH KO HEAT KIYA THODA. SAME ISSUE, FCH K BACKSIDE K 1-2 CAPS DIRTY THE, UNKO CHANGE, STILL SAME. TAB LAGA AB NHI HOGA. PHIR EK BAAR AUR DHYAAN SE DEKHA. CHIP K LOCK HATAYE TO EK TRACK BLKL GALA AND KATA HUA THA, JUMPER WIRE SE TRACK BANAYA. BOARD OK, DISPLAY AA gaya
