Re: Hanns-G Hi221DPB (Hannstar HSG1041) monitor: 2sec2black

Didn't know that, thank you, I'll search some documentation on those X capacitors and their role in the circuit. Theory has never been my forte but with luck I managed to fix quite a lot of devices and appliances in my younger days.

I still have a few other monitors with different problems - all mine, given by friends - but I'll take a short break to test this one before delving into deeper issues like corrupt EDID, waves of high and low brightness, falling to black in few minutes unless brightness at 100%...

Hopefully I won't be speaking too soon but… success!

Dunno if it was only that cap or bad solders too - which I had already fixed the other day - but as soon as I replaced the cap, mounted the diode and powered on it started working as if nothing happened.

I had to do a "gypsy job" - as we use to say around here - that is, place two 18pF caps in series since I couldn't find a 10pF on the BenQ spare board, but for now that's unimportant compared to the certainty that...

Yes, that's what I thought (and was afraid of) too.
Well, I'll proceed as soon as Lily (my cat) gets off my lap and will report back the findings.

First of all thank you for replying, I had begun to think I posted in a parallel universe.

By the 'X capacitor' you mean the blue ceramic one (10pF/3kV) that got the board brown around it? I wish that was the fault, not the tranny. I'll remove it, measure again the transformer's output resistance and maybe replace it if I can find another one.

I'll cram that 1N4148 in too, it sounds like it'd fit value-wise.

In the mean time I looked more carefully over the OZ9938 reference...

Hello everybody, I have a problem. As the title says, I've been hit by the "two seconds to black" train. Thing is, this monitor of mine seems to have been a great one because there's no discussions on it on the web, including here. No schematics either (or I'm too dumb to search properly). And yes, it's been working fine for the two-three years I've had it, bought used. Manufactured July 2009. Two days ago I woke up, started it, connected to the web, started mail application...

Re: New Members - please post your introductions here

I'd give an eye and an arm to have the past in the present, when boards allowed anonymous users to speak their mind, ask their questions or just view/download attachments without that much fuss. I spent a whole day all in all reading around so as not to come out as a greenhorn, went to sleep at 6AM, came back and now I have to wait for some script to allow me to ask a question. Maybe I'm too old for this and I've seen too much…

Anyway, it's almost 11PM here and while I'm waiting for the bots to do their...
