Re: Dell E172fpb
On top of BJT's, you should reflow the cracked joints along inverter-transformers leads.

Re: HP 1955 Monitor Repair Guide
I agree with Krankshaft. I usually reflow all of bad solder joints around the inverters when I fix HP 1955. If you take a look at the solder joints of inductor in the inverter ciurcut, you can see a circular crack around solder pin. Replacing parts without reflowing bad solder joints doesn't fix the failure.Leave a comment:
