Re: Newbie with Viewsonic VX2835WM Problem
Never overkill when it comes to photos, since it's the only thing that forum members have that they can use to help diagnose the problem. Looks like they used some quality caps like Chemicon KY series, which is probably why you got 5 years out of it. They also used some low quality Lelon caps.
Looking at your photos, there seem to be some bulged caps on the logic board: C198,C124 and C126. If you do a search on this site for VX2835Wm, you'll find these caps have caused problems for others.

Re: Newbie with Viewsonic VX2835WM Problem
Hi Guys,
Well i managed to take apart the monitor without any breakages and went about photographing the appropriate parts today when i had some good light.
I uploaded 8 photos, which i hope isn't over kill, i just want you guys to get a good look at what i am seeing.
The first thing i noticed (and i am a novice at this) was the distinct discolouration on the power board and the definite areas that looked burnt - black/brown with some sort of residue there. When you held it up it also smelt pretty burnt as well.
It looks, from what i have read on the other posts, that this power board has been running very hot (same as the Hanns G) during its life and has essentially burnt out - capacitors/circuits?
So what i am trying to establish with the help of the forum is whether it looks, from my pictures, that it could be saved or whether it really is set for disposal.
If you need more specific area photos please let me know.
Thanks in advance to the folks who can chime in with some help here.

Re: Newbie with Viewsonic VX2835WM Problem
Hi, welcome to the forums.
Everything you say sounds good, easiest place to start from is by opening it up and post some clear pictures of the boards.
When you're ready, click on "Go Advanced" and use the "Attach pictures" function you'll see there to attach pictures here, and then we'll see what can be done about that monitor.Leave a comment:

Newbie with Viewsonic VX2835WM Problem
Hi All,
I just wanted to introduce myself and highlight my problem.
I bought my vx2835 about 5 years ago and it has provided me with a trouble free life until the past few months.
I noticed that it wouldn't power up (no led lights) from start up and i would have to unplug the cable and plug it into a different socket to get it to turn on. It has been doing this intermittently for the past 2 months or so. However 2 days ago it wouldn't power on at all and there was a slight white flicker coming from the screen, i really thought that was it. I tried different sockets and cables but nothing.
I then started hunting the internet for some ideas and i came across this forum. This has now given me some hope! I admit i am a bit ham fisted when it comes to soldering but i am not adverse to learning new techniques and skills and i hope with the help of you guys i can get this puppy up and running again.
First thing i will do is take it apart and take photos of the boards/capacitors and upload for you folks to take a look at. I of course i will welcome your advice and knowledge as i have a lot to learn here.
Looking forward to the challenge!
Cheers

i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double... -

Good morning,
I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....
