Re: Sceptre X20WG-1080P monitor would not power up

Thanks to both RetiredCaps and Mad Professor. I almost hate to admit what the problem was because I feel like a total fool. But to make this be more helpful to others who may have the same problem I will explain. Because I only dealt with the power supply on the left side of the back of the monitor I did not pay any attention to the right side when I plugged everything back into the power supply. So I am sure your learned minds can predict what I am about to admit. As soon as I took it apart to get the specs for all of the caps,...

Re: Sceptre X20WG-1080P monitor would not power up

Thanks for the prompt reply, yes, I did power up several times after I turned on the computer, all with no signal detected. I even hot swapped between the crt and lcd and back to the crt--crt worked both before and after but the lcd still had no signal detected. The only change I may have done is to put too much force on those plastic plugs which you say are related to the backlights connection. I was able to push them back into place though and it seems if they were messed up the screen would not show the "no signal detected"...

Re: Sceptre X20WG-1080P monitor would not power up

I had originally tried to place this in the correct thread, Other devices with bad capacitors, but the site was giving me a hard time when trying to attach the jpg, something about logging in since the previous page. So I logged out and wound up adding it to FAQ. Can a Mod move it to the correct thread or do I need to delete and repost?

For several weeks I had a hard time turning on my monitor, if I would push the power button several times it would eventually power on and work fine. But a couple of days ago it would not power up after multiple attempts. The blue light would only blink like every 5 sec. So I used an old crt monitor and googled the problem. I found on other sites that the blinking light was a fault indicator most likely caused by bad capacitors. It also said to replace them in sets. When I took it apart all of the caps looked good except for a pair (circled in red on the photo) which are 1000uf 16v. I found this...
