Sceptre X9G Komodo IV 19" Flat Panel LCD Monitor Questions & Answers
Lcd monitor
This is a common fault on LCD back lit screens. It's called a "bad caps" fault. The capacitors for the light PSU have gone off tolerance and need replacing. If you know how to solder you can do it at home. Make sure to get the exact same type and value capacitors when replacing them.
Sceptre LCD - no display
There is 2 caps in the power supply that are blown
I have fixed 15 of these LCD with the same problem.

Look for bad caps, similar to the 17" version:

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps).

Sceptre X9G Komodo IV
I have a 19" Sceptre Comodo display. After 3 years it got the problem everybody complains about. Took it apart yesterday.
There are 4 capacitors in a row on the power supply board (it has a socket for the power cord and is covered by a metal shield. The caps are barrel-like things standing upright on the side opposite to the power cord socket.) Two of them are 470 uFx 25 V, they are next to each other. In my case, one of them popped up and another one was bloated. I pulled out the power supply board (make sure you unplug the power cord and press the power button do discharge the high voltage caps before messing with your monitor) after disconnecting all sockets (mark'em!). I assume that you have new caps handy (I paid $2.10 for a pair at a local electronics store), they must have the same capacity and voltage rating. Now grab a soldering iron, remove old caps, and put new ones in. You must observe polarity! (Usually "minus" pin is labeled on the cap's side. Mark down "minus" and "plus" pins location of old caps and put the new caps in exactly the same way! Otherwise, you can blow the caps.) If you are not used to work with a soldering iron, hire somebody or buy a new monitor. Check the quality of the work (no shorts, solid contacts, etc), assemble the monitor back and may be it will work (did for me). If it does, you put one monitor less into the city dumpster, be proud to get a working monitor for less than $5, and force you mother-in-law to take this shiny new replacement display she just bought back to the store.
Of course I do not guarantee that my procedure will work for and you can use it at your own risk only (i.e. I am not liable for any damages).
Sceptre Komodo 2
First open monitor (with power off) find power supply, this is the part where the AC cord plugs into. Inside back of monitor you will see a small board with components on it. You should see a big capacitor. It should be round with 2 leggs sticking out going on the board most of them are layed down, sort of bent over. this is probably the ac filter cap for your monitor, it should have something like a number with UF behind it and at 100v or 160v or depending on monitor. Sometype of voltage this is what you need to change and look for some other out of place cap. Beset is to change all large ones. You can find caps at www.bluestar-online.com. These are electrolytic caps. There are many different kinds. Hope this helps!
Unidentifiable capacitor?
What i would suggest is taking those numbers going to your favorite search engine and entering them. Alot of times search engines can give data concerning hardware parts just by there manufacture number. This will give you a foundation to find what that particular part is and also maybe a replacement part. A word of caution about working with capacitors. Even after power has been off for several hours they can still hold a deadly charge. If you have a volt meter I would use it to test the part before even thinking about it. Capacitors are nothing to mess with unless you have proper knowlege on how to handle them and discharge them.
My Sceptre X9G Will Work for a 10 mins or so then
Hello,
You have a power supply that is about to die.
If you can solder you should be able to repair the monitor yourself.
The problem is caused by blown capacitors on the power board. Go to our
web site at :
www.ccl-la.com/badcaps.htm
We have pictures of what to look for. Open your monitor and look at the
power supply board for any blown capacitors, replace all that you find.
The replacement parts can be ordered from several places on the
internet or we can supply them for you. The replacement parts will need
to be high temp and will be marked 105c. The values you need to get
will be marked on the sides of the ones you take out but will be
something like 220uf, 470uf, or 1000uf etc. and then a voltage rating.
When you install the new ones be sure to insert them with the polarity
stripe going the same direction as the old ones come out. If you don't
want to do the repair yourself we do offer a repair service for $35
plus return shipping. If you have any questions just let us know
I hope this helps if so please rate our solution.

It may have dying power supply due to bad DC filter caps like the 17" version.

Where to find capacitor
www.bluestar-online.com, mcmelectronics, tritronics etc. You will need to heat up the soldering trace, or legs of capacitor and pullout gently.
Dead scepter x22 monitor
Had a Sceptre DCL9A model for mine. There are plastic snaps which hold the back and front covers together. After I took off the screws and detach the monitor stand, I slid a very small flat head screw driver along the sides until I found each snap. They should come loose easily with a slight twist of the screwdriver. There are about 5 on each side of the monitor (not counting the monitor). Do not try to force it as you can warp or crack the plastic.
I've got a Sceptre 19 in monitor with the typical
You need to use a plastic scribe to run around the edge of the monitor seam. A plastic scribe is a tool that looks like a knife, but it is not really sharp. Pry into the seam on the monitor and gently but firmly work around the edge until it pops apart.
Connecting second monitor
Not sure If I am understanding this correctly, you are trying to connect a monitor to a monitor? I have never heard of that before. As far as I know you need a video card that has dual output to use dual monitors. I am not saying you can't do what I think you are saying but I never heard of that before. Also on a side note depending on the resolution and amount of colors your operating system is set on, you need a video card strong enough to drive both monitors.
Monitor Problem
Use ctrl+alt+ up Arrow key on your keyboard (you can also use use ctrl+alt+ left/right Arrow key)
Good Luck
Monitor just says no signal
i had the same problem with my PC too ....
the problem was with the RAM ... the signal was not passing through it ... .
if u got 2 RAM'S try using one at a time u will find out the faulty one .....
hope it solves u r prob...
