Re: So I've got a dead 27" Viewsonic VX2753MH
I don't know if anyone's kept up on this thread, but I have found a source for repair; let's cross our fingers!

Thanks; I've probably got some crap around here I could experiment on....Leave a comment:

Re: So I've got a dead 27" Viewsonic VX2753MH
Okay so a slight follow-up to this: can anyone direct me to somewhere I could get this board recapped and the power jack repaired at? None of my fellow nerd friends skills are in that area, and I'm damned afraid of just killing the poor board.Leave a comment:

Re: So I've got a dead 27" Viewsonic VX2753MH
I haven't had a chance, but I will post back as soon as I have the opportunity to try and affect repairs. Right now it's down to re-soldering the power input jack and replacing the caps. I'll have to find someone to do it for me as I am all thumbs. But once I've gotten those things done I will report back. I'm keeping an eye on the thread as I want to see if anyone else (such as yourself) comes in with any more issues or suggestions. One thing I can tell you, though, is prepare for a fight to get the monitor apart....Leave a comment:

Re: So I've got a dead 27" Viewsonic VX2753MH
Gotcha. Ounce of prevention and all.
The "neighborhood scrap guy" picked up a box of laptop parts (like, seriously broken laptop parts) but otherwise it just seemed like people from around the neighborhood grabbing them up.
I scrapped probably 30+ Pentium II and III (like 266-533 mhz machines, pre winxp era HP boxen) and that tiny handful of parts that came to like 10-12 machines was all that was worth keeping, and I thought "Keeping for what?" so...Leave a comment:

Re: So I've got a dead 27" Viewsonic VX2753MH
I will give all that at try, too, thank you! But, again, I don't think a failing power brick explains two ports going bad (not bitching at you, I promise, just very curious situation!).
As to "scrapping" it, yeah, that's more what I meant. Trust me, as an IT dude I don't throw e-waste into the "normal" trash. Heck, a few years back I built piles of Athlon and Celeron machines out of junk I had in my garage and stacked 'em on the curb for free.
You'd have thought I was giving...

If it wasn't for the VGA port and then the first of the two HDMI ports going out, I would agree that it might be something that "simple".
if, after I get the power connector re-soldered and new caps put on it still does it, well...I might try a new power brick or cord but beyond that I'll likely scrap it...which pains me to say....Leave a comment:

Re: So I've got a dead 27" Viewsonic VX2753MH
Right on. I'll see if I can get one of my soldering-iron wielding friends to assist me here. I really hope it's a combination of the caps and power jack and nothing (say) with some tiny resistors or something.
It's funny, I thought maybe I'd find one for sale somewhere and cannibalize it for a good board but the only complete ones I could find were NIB or refurbished models for like...$300. I'm guessing this was a fairly popular unit?...Leave a comment:

Re: So I've got a dead 27" Viewsonic VX2753MH
I'm going to try those things, thank you for the suggestion. Also, while you can't see it in the photos, when I had the board on my workbench I used my mag-eyes plus a magnifying glass and noticed that yes indeed there's a crack around one of the power connector joints! So that clearly is gonna get the treatment.
I hate to ask you to speculate, but do you think maybe it was a combination of two things: bad caps and a bad power lead? Hence losing the VGA and one HDMI port...? but then how does that...Leave a comment:

Re: So I've got a dead 27" Viewsonic VX2753MH
Okay, so, an update. I pulled the board out, and checked the connectors. They're firm, don't seem to move, and to my eyes there are no cracks or gaps in the solder.
Here's the photos:
I don't have a probe, so I can't tell what's going on when the power is connected. I will say that while I had the board on the bench, I connected power, and the...Leave a comment:

Thanks, piernov; I will re-disassemble the display later today and pull the board, try those things, and include some photos....Leave a comment:

So I've got a dead 27" Viewsonic VX2753MH
Hey all...
So, I've got a Viewsonic VX2753-MH. Currently, it doesn't power on. Symptoms/pathology are thus:
Couple years ago (maybe more than just a couple? I think these are a good 6 years old in terms of introduction), the VGA port just quit working. No problem, I switched over to HDMI. Then the HDMI port next to the VGA quit working. I tried the next HDMI port and it worked from there on out.
However, two years ago, it developed an intermittent power problem. The plug for the power source would sometimes have to be re-seated, or fiddled with, to... -
Re: New Members - please post your introductions here
Hey everyone! Bill S. here, been computing since I first got my hands on a (wait for it - !) Commodore VIC-20 I had connected to a huge old fish-eyed TV set! I stumbled upon this site while looking to fix my ailing viewsonic display (and I hope I can with some help from folks here!). I do some freelance writing work in information systems too, but it's mostly about networking, databases, backup technologies and so forth. Fixing displays is voodoo to me!
Anyway, thanks for having me aboard.Leave a comment:
