Default Re: Repairing Bestec TFX0250D5W

PeteS, the inrush thermistor measured 3.4 ohm. There is no damage on it but some white adhesive is on it.

BTW, tried to do some testing while waiting for the MOVs to come in and blew the 5v stand-by control chip, U2 (TNY276PN). Ordered some of these too. I had replaced the bridge rectifiers diodes and fuse and the chip blew as soon as I plugged the PS into the outlet. I hope it was already damaged and I don't end up blowing up the new chip.
The hot side power was normal when I checked it after the chip blew.
