SOURCE: transistor lost.

if you are replacing 7402
also replace diode 6404 this diode even thou it test goo will in long term overheat 7404 and caus it to go bad by leakage.
and if 7402 gose bad it is regulating the 15v stanby volts that is 7412 is also going to be bad so replace 7412 also
now
the part numbers are:
7402 = # 932211676682

7412 =# 932210514682


thanks,
daniel.

I want to know the value of transistors. my Philips TV 25PT4473/69T power supply is blown up. If Circuit diagram could I get


You have to try in Google search.

If the transistor body is not damaged, you can read the type no. Replace it with identical No. Make sure the diodes and capacitors are not damaged. Check with multi- meter

I need the electrical diagrams to repair my rear projector model 55PW9383/17F Chassis DPTV340. Failure: no power on


You prob do not need a diagram to figure out this problem. If it powers on, then powers right back off again, then you could have a serious horizontal transistor short. If the TV is just dead period, you can try to replace all the large capacitors around the power supply area. A bulging top or leaking around the bottom are nice features to identify problem caps.

Hello, you (tech) can try this remedy - 1500 = fuse (250V/4A) - 3523 = resistor (47R) - 3527 = resistor (0.22R) - 3532 = resistor (2.2K) - 6500 = diode GBU4JL7002 - 6523 = diode 1N4148 - 7520 = circuit TEA1507P/N1 - 7522 = transistor BC847B - 7521 = transistor STP10NK80ZFP - 6526 = diode BZX384-C22 - 7515 = optocoupler TCET1104-G - 3526 = resistor (0.15R). - 3526 = resistor (0.22R). If you need more info please advice. Arpi
