I think the heat problem is quite serious, I actually smell something burning after leaving the monitor on for 5 mins.

Re: ViewSonic VX924 No power - Not the usual suspects
Thanks for your advise retired, but I can't make out the number.
Well I have another working VX924, maybe I can open it and compare the two. But it does not have such noise while in operation. The repaired one makes this faint rattling sound while powered on, kind of like what a damaged fan will sound like. And is it normal for the beeping sound to be there?
Here's a bigger pic, if it helps. Thanks...Leave a comment:

Re: ViewSonic VX924 No power - Not the usual suspects
I took out the monitor and replace all caps again. It seems to be working, but something bothers me. The red circled heat sink feels very hot within minutes, while the blue circled one is stone cold. And I am hearing this faint rattling sound while power is on. And with power off I can hear faint beep sounds, even if I off the power supply but leave the power cord plug in, the sound still remains. Any1 can advise what seems to be the problem?...Leave a comment:

I left the monitor alone for some time. Then I remembered 1 CAP 330uF 35V I replaced with 330uf 50V. So I got another 330uF 35V and put it in place. The monitor works, but only for 1 day. The next day I try to power up, I get the blinking light again.Last edited by wsqlim; 03-22-2011, 11:48 PM.Leave a comment:

Re: ViewSonic VX924 No power - Not the usual suspects
I have "the blinking" power LED problem as well. After replacing all the capacitors, it still fail to power up, still blinking LED. I'm getting unstable 8-9DC on the power output side. What can be causing this and how to fix it?Leave a comment:
