Dell E193FPp Repair Tip
« on: March 16, 2010, 01:50:56 pm »
As a favor and side job, I am the on call IT guy for my neighbors' business.  I get calls that run the gamut of fried LANs due to lightening strikes, to "why doesn't my mouse work".

So last week one of their Dell LCD monitors "had just gone out" and wouldn't power back on (not unplugged!). Noting that many Dell's seem to have issues with caps in their inverters and PSUs, I told them they were S.O.L. after some routine troubleshooting. Rather than toss it, I asked if they would let me dissect it to satisfy my curiosity.

Shortly after I got a call about how to make the new monitor "not all stretched and blurry".  But I digress.

Long story short, all the caps were fine, diodes all looked good, etc and so forth.  I started going over the underside of the PSU with a magnifying glass, and it turns out there was a bad solder joint that had cracked where the IEC power jack mated to the PSU board.  Touched it up and she's back to life 100%.  Neighbor didn't want it back now that they had a pretty WS Samsung, so I've got a nice (free is nice!) 19" LCD for a future mame project

Thanks for the tip.... always good to hear of other possible common faults on things like this.
Not a technician . . . . just a DIY'er.

Hm....I'd all but given up on one of my Dells. I've shotgunned all the caps, driver transistors, even the little 'box caps.' Trying to get it back to life.

Next step is to reflow the board, methinks.

(like I NEED a reason to fire up my iron??)
Man, will my cab EVER be finished?
