Hello,
I am troubleshooting a POLAROID TVB55R4PR004 TV which has a short circuit when the inverter tries to start. I checked and replaced some faulty components.
On the card (reference CV3458H-A50), I have two integrated circuits marked PU1 and PU2 which also seem to manage the switching power supply. An inscription RBt 35 CZ is noted on it.
I am therefore trying to find out which component it is in order to be able to find the datasheet or a diagram of the card.
Thank you in advance for your feedback.
Best regards.
