Does replacing the PSU get rid of the buzzing noise common with this model Soyo? Or is that noise generated by a different component?This thread is probably hardly read by anyone at this point, but it must be a testament to the perceived quality of the Soyo monitor that so many people would care so much to keep the darn thing working.
I bought my monitor 4 1/2 years ago at Office Max, then about 2 years ago I did the Taobao upgraded power supply fix.
In recent weeks after a couple of hours the monitor would suddenly momentarily show strange colors as if one of the RGB channels was dropping out. Then last week from time to time there would be horizontal streaks flashing on the screen. The streaks gradually became more common, and finally a few nights ago I sighed and decided to crack open the case once again. I hoped that if it was a mechanical connection then I might be able to just disconnect and reconnect all the internal cables and all would be well.
Well, I did that, but in addition I noticed a smallish aluminum panel screwed to the bottom of the display. Underneath were a half-dozen chips, and curiously it looked like some of them had heatsink compound on them, mating them with a gooey heatsink material on the aluminum plate. But some of the chips were not covered at all with compound. Hmmm. Could they be dried out and getting too hot? I put on fresh compound, buttoned everything up, and so far the monitor is as stable as a rock. The lack of heatsink compound could have been the issue, or maybe it was a poor contact in one of the connectors, but once again the monitor is performing great.
I do note, however, a slight burn-in. Curiously it appears only in the upper part of the screen. I wonder if some LCD goo of some sort is slowly migrating down to the bottom.
There's a particular brightness level in which the buzzing noise goes away (slightly different on each Soyo I've used), but that level is way too bright for my eyes.
