Re: LG Flatron W2353V - Two hours to black


I don't remember where I found these, but here they are in attachments. Just be advised, that some components on these diagrams differ from those on my board (perhaps different revision). Also, I would be glad if you'll post your progress.

As for my progress, I changed most caps on logic board without success. Thanks to [b]jetadm123[/b], it's obvious to me now, that power board has nothing to do with that fault. Nevertheless I'm stuck.

And for some good news: in the meantime I succeeded in repairing...

Re: LG Flatron W2353V - Two hours to black

I wish they were, but they are some unknown to me brand from local store. The old ones were Su'scon SK/SG series, are they considered low ESR?

Not yet, but now I'll buy them as soon as possible. Also, there is one small SMD type cap on logic board, should I change it too?

As for the voltage chart - yes. "Sleepy" means that I waited until monitor goes to its faulty state and then checked voltages on board....

Re: LG Flatron W2353V - Two hours to black

Changed another cap on power board. Also redid soldering on some suspicious joints, but nothing obviously criminal. Tried hair dryer thing, but didn't saw any direct effect. Nevertheless, I don't have any experience with this, so here is what I did.

Turned on monitor and started heating power board for couple of minutes - no effect, switched to logic board and after some time monitor turned black (could be coincidence, because of time). Next try - same result, just shorter time period. Tried another technique: preheat board...

First of all, I wanna say hello to this great forum and its inhabitants. Found some interesting readings here through google, before decided to register myself.

Now to the point. Bought this monitor new in 2009. Served flawlessly for 3 years, until started to get sleepy. First it happened once in a couple of weeks, then days, now it's hours and minutes.

[U]How it looks[/U]
Screen suddenly goes black. Power LED still shows active state, but all of the touch sensitive controls are unresponsive. After reconnecting power cable monitor might turn on, but for a while....
