Turn on power supply, So process battery go on and Wait down until two strips
Subtitute voltage tension
To analyze hand phone problem pass test point need tension batrei. as subtitute as tension batrei we can uses power supply.
Solution :
Jumper parallel engine /PCB part (BSI, Btem and -) and Giving cable as switch place
Setting voltage of power supply according as battery tension. Kill and Coll red cable on (+) and Black on (-).
Turn on power supply and pressing switch on/off of hand phone
As analysis of handphone problem
when normally condition, When we test use power supply so tension that produced show tension value that fluctuate between 0,15 up to 0,2.
Solution :
Setting voltage of power supply according as battery tension, Then turn off.
Colling Cable of power supply in battery konektor as according the place
Turn on power supply, pressing switch on/off and analysis ampere needle movement, As follows:
Ampere needle movement on 0,15 is Power's position. Trouble Shooting :
If switch on/off of ampere needle depressed has rised and Direct go down to 0, so IC Power has failure
If switch on/off depressed ampere needle has rised, idle then down to 0 or idle above 0, it means memory has failure
If switch on/off depressed ampere needle was fluctuate but Hand phone die, it means program memory is failure
If switch on/off depressed ampere needle was not move. Check:
Switch on/off.
On/off Stripe
Tight of resistor on/off
Ampere needle movement on course 0,25 be CPU's position
Ampere needle movement on course 0,17 be RX's position (reiceiver)
Ampere needle movement on course 0,13 be TX's position (transmitter)
Before switch on/off switch, but ampere nedle has value. it means konslet.
