Call help ... My Advantest R3271 canot boot after I changed all E-CAPs
williamlee:
Hi all,
My Advantest R3271 cannot boot after I changed all E-CAPs of PSUs(2 BOARDS). Because of smell BBQ ... :phew: :phew: so, I decided to open it. What I found is that 60% E-Cap has leaking.
But after E-caps changed, I put the 2 PSU back and turned the power on, I only saw the buttons light around half sound ... and then, everything is quiet, no display, smoke, and explode. :-DD :-DD :-//
Can any clue to me? Thanks a lot

Troubleshoot the power supply on its own.
whether voltage is normally present on each power line when run by itself. :o
:-BROKE
coppercone2:
more then likely you disturbed a very damaged trace when replacing the caps that took it out totally.
williamlee:
No display and no boot activity(buttons led just light within 0.2 second :-DD) . I tried to test each power line and it's totally not normal -// :=\ :-DD really sad, especially for a beginner like me. I am sure that the capacitor change is okay. (I did ifr 1200s)

I was careful and used HOKKO FR-301 for the desoldering job. :palm: :palm:
