Asus VW193D (VW193D-B) repair, blinking led

[Chungalin]

I can't see any other case of this monitor model, so I report.

After disassembly I found bloated C802. C939 too, subtly. C915 wasn't bloated but showed too high ESR. Replaced all, and left long legs to C802 in order to separate it from hot inverter zone that kills it. No problems after this.

Other relevant components inside this monitor:

-LM190WX1-TLC1 [Panel] LG Display 19,0" 1440x900
-TEA1530AT [IC901] Philips-NXP primary controller SOIC-8N
-STP10NK70ZFP [Q901] ST primary switcher mosfet TO-220
-P5506HVG [Q802-3] Inverter dual N-ch mosfets SOIC-8N
-SB1060FCT [D905-6] Secondary schottky barriers TO-220

Good info . Got pictures, though?

No, I never take pictures of easy repairs, but in the last 2 years I've been building an Access database of main components found inside equipment I repair (transistors, big diodes/schottky barriers, selected ICs, belts, optical pickups, regulators, audio amp ICs...). This is specially helpful to locate components within sets I have for scrapping purposes, instead of taking apart everything.

Ideally, this database should be online and cooperative, like wikipedia. This could be a nice project.

Yes, I started doing that as well - at least with transistors and MOSFETs, that is. So if I need something, I know which board to look on.

That would be nice. But it would be a HUGE database. Just a single PC motherboard usually contains at least several different regulators and MOSFETs, along with coils, controllers, and whatnot. With all of the different models of electronics out there, you can imagine how big the database can get.
