Hello everyone I was hoping someone might be able to help me identify this IC. Its a Toshiba 50L1350U LCD TV with power supply pk101w0050i. There are numbers on it but they are worn enough I can't read them.
This set is dead with standby volts and no standby light along with:
No volts at C601
questionable MOSFETS Q101 and Q102
Q502 appears OK
questionable X2 capacitor CX101 (Carli .33k275V X2 40/110/56, known for failure in coffee makers)
On the cold side:
Diode D301 accidentally shorted across pins EL203 and EL204 with power present.
Voltage of 12.4V present at EL203 after short
Loss of previously present 12V AUD and 12V_CC voltage of 12.4.
Resistor R903 appears open.
Prior to short of EL203 and EL204 the following voltages were present at connector P802
PWM: 3.1
BL_ON/off: 0.0 (set will not power on)
AC_DETECT: 3.1
5.1V: 5.3V
12V_LNB: 0
12V_AUD: 12.4
12V_CC: 12.4
So I'm thinking of buying the individual components and soldering them in but just wondering if anyone thinks I missed anything?
