Having problems with your Computer Monitors ?

Sceptre LCD - no display

\015 My Sceptre LCD X9G-Komodo IV is no longer worked as usual, the screen stopped displaying. If I press the button OFF and ON again, the monitor will display information for about 1 second and after that the screen is blanked/blacked out even the power is still ON (green). Could you please help me to resolve this problem? Thanks\015\012SAME AS all the other monitors in this section, screen goes black, power light stays on, comes on for a second or two and then black again; tried another computer; this time fired up once and then black for good. Only a little over a year old. Brand Visiontek by Batesias.\015

Answers :

It may be the capacitors, since capacitors run about $1.50 or so depending on size you may spend a little over $6 total if you already have soldering equipment or a friend with skills.
It sure sounds like the capacitors on the powerboard. Here's a possible solution. There are four capacitors in a row on the power board ( the one with a single huge capacitor and several other ones in a seperate section) There are two seperate boards in the monitor, when you open it up it will become evident. The capacitors to replace are in a single line, two smaller then the other two. They are rated 470 uf/25V and 1200uf/10V Total cost of the 4 capacitors is a couple of bucks. You need to replace all four as it will be difficult to determine which one is acting up. Reason why your monitor is failing to display is because one of the capacitors is not holding it's charge and when it demands power for displaying the graphics it can not deliver. So, replace all four capacitors 2 x 470 uf and 2 x 1200 uf and your display will be fine. Of note, when you power up after replacement, it will take just a heartbeat for the capacitors to charge up so you may see a little flicker and a bit dimmer screen at first. That should all go to normal within a couple of seconds. Good luck

I have a Sceptre x22 gamer that has been serving me well for about two years. A week ago I started having trouble getting the monitor to ''Wake Up'' after the computer goes to sleep or when rebooting. It has become so bad recently that I had to turn the monitor on and wait 15 minutes before it would start to display anything. I don't think it is an issue with the inputs as there is usually a blue display that comes up whether anything is plugged in or not. Usually you are able to switch modes wh

For the past week, when my Sceptre LCD monitor goes to sleep after inactivity, it won't restart immediately. The blue LED blinks every second or so; eventually, the screen begins to flash the display, and then a few minutes after that, will finally turn on. Sometimes the whole process takes five minutes, sometimes an hour. How can I fix this problem? (I can't find the documentation to say exactly what model this is; if that's important, I can look again.)
