Re: What may cause LCD monitor show image for a moment and then go standby

Dear Friends, as a follow-up of the story, I'm glad to tell that repair
was successful, even though not without curious minor incident :)

The girl, my friend, opened the case and eventually got to the power
supply board (as usually, the larger one). I explained her your
suggestion about search for faulty capacitors and when she sent along
the photo, we easily identified a couple bloating ones 220uF * 35v.

Thus I guided her to the local components shop and she replaced them
according to my instructions - though as it was her very first
experience of handling soldering iron, and my instructions were given
remotely - there were minor damages to the traces etc. Thus the thing
even stopped blinking as before. Today she brought the "patient" to me
and after some puzzling we were able to identify tiny scratch and repair
the broken trace. Works like a miracle now, thus the hint about
capacitors was 100% exact.

- one last thin trace connected with wire (in lacquer isolation)

She expresses great thanks to everyone and says this was extremely
interesting experience :)
