Re: Viewsonic 27" LCD turns off after a while -- longer on VGA, Shorter on HDMI?
All I could find in my parts bin was a 40uH ; of a higher voltage rating probably (it's bigger) ... and I'm a risk taker, so I swapped the stock inductor in the position that was getting hot obviously... it's been running for an hour now without shutting down. Just a band-aid on the situation, i'm sure -- since the IC INL858RN -- IS getting hot, maybe a short, thus overheating the inductor perhaps? The only diodes I can identify on the PCB are the larger black diodes, I think there's three , maybe 4 of those and they all test ok... the smaller stuff i'm not sure whats a diode, which is why I took the close up pics around that IC that is getting toasty... It's getting around 120F I think from what I can tell.
