Re: Gateway 900G 19" LCD monitor: LVDS cable GLUE?
Ops not going very good it has seen better days
How hard would it be to put a buck converter board in place of the lm7812
Because they also make switch regular that runs a lot cooler and does not require a heat sink unless you run the hell out of it they have voltages from 3.3/5/12 and an adjustable version as well of this type of regular
Here is a website that sells the 5 volt version of this type of regulator I have used them in the past and they work very well and do not run very hot

Here is the 12 volt version of this type of regulator however they do not offer the single power rail anymore unfortunately but you just make a board using the same exact parts
https://www.futurlec.com/Mini_Power_Dual_12V.shtml
Here is the 12 volt version 3 amp version of the same type of regulator
LM2576HVT-12
Here is the 5 volt 3 amp version for this type of device

Other option is to relocate the 7812 to a different heatsink perhaps, but I just noticed something else...probably have to desolder the diode but I noticed it seemed a little leaky... this would cause some heat...Comment

Welp, in went some new caps and the monitor is alive again. Posting this so I have a record when I last changed them...again...
Some Chemicon and Nichicon caps went in this time, and two 470uF 25V caps went in instead of a 1000uF 25V. I think the former might be better as it's more surface area to dissipate heat.
Now...when will be the next time I repair this monitor...Comment

Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

Hi there!
Someone gave me their old monitor, it's Dell S2715ht.
The owner was using it when his PSU began to smell and then to smoke. It literally began to melt. He turned the monitor off, pulled the PSU, and ditched it because it was smelly even after it cooled. So I got the monitor but not the plug.
Now, I tried to bring the monitor back to life, by plugging one of my many Dell laptop PSUs. They are of the same 19.5V, and the wattage of the laptop PSU is higher than that which the monitor is rated for. Visually, the socket on the monitor seems compatible, and the plug plugs... -
Hello Badcaps Community,
I purchased a preowned AOC monitor that is not working and out of warranty. It was sold as not working. I am looking for guidance on self-repair. In particular, I am after the firmware for the monitor. At the end, I have included monitor model information and links to pics and vids of the issue.
The problem is that it will not display a picture on any of its inputs. And the on-screen menu does not appear. The power button works properly. It powers on with the remote as well. But the on-screen menu does not appear, even when not connected to any... -
12v pin is shorted to ground in the LCD board (1st picture) if the LVDS cable is disconnected, 12v are OK in the Main Board (2nd Picture) -
Hi Everyone
Lately I am experiencing the deja-vu incident on one of the led monitor like this.
https://www.badcaps.net/forum/troubl...lashing-on-off
The monitor is HP 27es LED Monitor
https://h30434.www3.hp.com/t5/Deskto...e/td-p/6804692
The monitor will randomly blackout and display no signal and will recover again.
Sometimes need to power and off again to restore the display but...
