Having problems with your Dell UltraSharp 2405FPW 24" Flat Panel LCD Monitor ?

Click, small puff of smoke and dead.

\015 Had the screen turned off and when pressing the green button, a snapping 'plick' was heard and an very tiny puff off smoke came from the ventslots at the top on the backplane, verticly above the buttons.\015\012The screen is three years, and one month, of course, old. Can i open it, and in yhat case how, and look for any components likely to have falied or is everything integrated in cicuits?\015

Answers :

I had the same problem as lasselson. The monitor apparently failed with a "bang". Followed instructions on YouTube to get the case open. C605 capacitor had failed in exactly the way described, and the main fuse (T4A 250V HBC 20mm x 5mm) was blown. I could find no other damage at that point so replaced the fuse (in a holder!) and cap, put the cover on, applied power and "Pop!".
\015\012Had another look and found that IC651 had part of the top blown off. (The big resistors standing off the board all seem to have survived though).
\015\012Amazingly I found the top of IC651 and with a tiny dot of superglue, put it back in its original location. Had to scrape off laquer and clean the residue with isopropyl alcohol. This revealed the ST logo and figure "6561". Did a search and I'm pretty certain this is the L6561 Power Factor Corrector:
