Blown resistor on plasma PSU

[Blake]

I have the same problem with r133 blown out... I replaced the resistor and tried it out. It did more damaged that was done previously... Any suggestions would be much appreciated.

Check your transformers, one of them is defective and is ruining the resistors.

Hello all! I know it's a bit on the late side but I have the same problem with the pcb2310 pioneer plasma TV power supply board. I have replaced the cap (C106 250v 648nf), diode package (DU101), and resistor (R133 0.1ohm).

The reason I replaced the capacitor C106 was because I wasn't getting any voltage beyond that point. After replacing it the first time, it made a huge pop! After replacing the DU101 and the C106 (again) it ran fine for a good minute then just shut off. Next I saw the R133 complete fried so I replaced it (Brown, Black, Silver, Gold). Now R101 and R102 start to smoke and get really hot and the power button has no affect.


Thought I would throw this info out there who ever is still messing with these TVs still
Good luck!
