TRIPS IN 200mS and ON after 5.34S and Cycle
All PREVIOUS supply exists along with 3.3VALW and 5VALW SUPPLY LINE EXIST CONT. AFTER TRIP
BUT VCORE FOR 100mS Only, PL5301 GRF CORE FOR 200mS.
EC Pin24 of SIO PMPWROK for 64mS
PIN14 VTTPG for 208mS
EC Pin124 PCH_THRM ALERT# LOW FOR 1.25SEC than HIGH.
BY KEEPING PMPWRBTN# PIN LOW BY 100 OHM PROBE TO GND NO CHANGE.PIN 96 ALWAYS REMAIN HI.
SO REFLOW PCH, NOW BOARD CONT PWR ON.
1.35AMP BOOTING Ok by USB init.
NO DISPLAY 3BEEP
PSU shows 0.12AMP
NO 1.05V supply BUT 1.8V 1.5V 3VS-5VS OK
BUT RUNPWROK 0V
so REPLACE 1.8V SUPPLY APL CHIP REGULATOR
TEST by USB Init all OK
NO DISPLAY,PSU 0.75AMP
15ALW OK BUT U4203 GATE VOLT 1V SO NOT XFER VDDQ
FOUND U4203 N-CH MOSFET LICKY
REPLACED OK
NOW BOOTING BY USB INIT OK BUT BLANK SCREEN PROBLEM
PANEL SM BUS SIGNAL SEEMS OK
RN5501 DIODE VALUE NG
PCH REFLOW OK
POWER Trips after power on
BUT 3V- 5V on RESPECTIVE coils PRESENT
Controller heating TPS51125A and PSU shows 0.13Amp
5V short at HDMI PORT
