Question about Sceptre X9G Komodo IV 19" Flat Panel LCD Monitor
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
Just had the same problem on my Sceptre Naga IV. It was fairly easy to take apart and i had to replace all 4 capacitors(2 470uf 25v and 2 1200uf 10v). Bought them from mouser.com for less than $3 total, very easy to unsolder and solder if you have any experience with it at all. Monitor is working like new :) Hope this helps

I recently came accross one of these monitors (Planar PE191M) with the identical issue. The resolution was to replace the two 470ufd 25V capacitors that are located on the main power board. The main power board also contains the audio circuit and more importantly the inverter circuit that drives the CCFL backlighting. The suspect caps were identified using an ESR meter; if you happen to have one of these meters you can confirm this is the issue with your unit(s), alternatively you can just replace the two capacitors and see if it resolves your issue. Hope this info helps someone out there.

I followed the advice posted here and on other fixya.com forums, -- namely replacing the tow 409uf 25vand the two 1200uf 10v capacitors, and the problem is fixed. This is on a Sceptre x9 komodo IV. Bought the 470uf 10v capacitors from parts express for 52 cents each ($1.86 shipping first class mail) and the 1200uf 10v from an ebay seller (10 for $1.29 plus $1.69 shipping) from k_electronics. Extremely reasonable price and shipping.

I doubt if this is cable-related. i had a xerox 19" monitor that blanked out faster and faster the warmer the monitor got. if you find that the screen display lasts longer if it is cold, say after you have left it off overnight, then your problem is definitely somewhere on the power board. as the monitor is used more and more, warming up and cooling down, any solder joints that are weak can break, so that the connection exists only when the power board is cold (expansion of the metal) and quits displaying when the power board is warm (contraction of the metal). if you aren't afraid of soldering, pull your monitor apart (be very careful to remember how to put it back together) and try simply touching each of the solder points on the power board. be sure to use only no-clean solder as its flux is non-conductive and non-corrosive and also not to bridge any of the connections that were not previously connected. good luck.

Your problem is the video inverter, you can see an image for about 2 secs or so, then it goes blank and the power light indicator is still green. sceptre wants 125.00 for this part IF you can repair it yourself.

I had the same problem with my DCL9A 19" DCLCD monitor. It would turn on for a few seconds and then black screen. The same thing every time you power on the monitor.
I disassembled the LCD and then removed the power supply board, desoldered and removed the 2-470uf 25v caps along with the 2-1200uf 10v caps and checked all with my LCR meter set on 0-2000uf range. both 1200uf caps were ok but the 470uf caps only measured around 100uf. I replaced both of the 470uf 25v caps and it solved the problem. My DCL9A is now working perfectly!

This problem is very often caused by dry electrolytic capacitors on the inverter board. If you have some skill with soldering you could try to change them. When buying new ones ask for LOW-ESR capacitors for switching mode power supplies (SMPS) and 105°C, they are a little bit more expensive than normal electrolytic capacitors, but are designed for this aplications so they lasts more. Normal el. caps will also works fine so when you cannot buy LOW-ESR for SMPS use normal ones.

The above solution sounds like a waste of time to me, though I'd have tried it if I had another monitor cablel lying around...I've got the identical problem and have seen another couple of similar posts about this, but no repair tips. I expect it is a power-supply problem, since there is a dim but otherwise-normal picture for the second or two before it shuts down. Some $0.39 component has gone bad...but which one? Notably, I returned the first identical monitor within days of purchase for a similar lights-on-but-no-display problem. At this point I may have to write it off and buy another...and methinks from another mfr. I expect more than a year or two of trouble-free use out of ANY monitor. Is that asking too much, Sceptre?

This trouble maybe power supply or inverter boards is defective.
first you can test the voltage of the multr,and then check which part is defective.From Wisiny.com can find those parts
if you have any question,please let us know email:[email protected],we sincerely hope we can help you!
you can also check this boards whether suit you:

Not capacitors problem but transformers.
I learned the problem caused by the invertor here. But no problems were found after checking all capacitors on the power borad and the inverter board. I was curious about 8 black boxes on the inverter borad and measured their resistances between different connectors, found the one on the left is quite different from other seven. Then I goodled it and found out they transformers. For my inverter board (darfon v144-001), the primary resistance should 0.5 ohm, the secondary should be 950 ohm. I ordered the replacement from lcdparts.net and installed it on the inverter board, and my Sceptre XS30V-NAGA III works again. The probablem is fixed.

Replaced the caps on my Sceptre X9G Naga II monitor as directed on this page. Now it's good as new! Thanks for the fix!

Have a Sceptre X7 monitor that displayed the same symptoms -- powering up okay for a second or two, then merely blinking the blue light.
After reading the information in this forum, I dismantled the monitor and replaced the two 470uf/25V caps (used 85* caps since that's what I have). Works perfectly now.

I have this exact same problem on TWO Viewsonics....so yeah...can't say it's isolated to Sceptre.

I have a X9 NagII Same **** - I replaced the 4 caps (2 470uf 25v and 2 1200uf 10v) like in Solution #8 & its up & running again. I bough them on ebay - A hellua lot cheaper than 4spending another $175.00 for a new monitor!

More than 90% of time it is the caps. check the cable , that is too funny.

I am having the same problem. The backlight inside the monitor is not working correctly (screen displays fine for 1-2 seconds after starting up then appears to go black). From what I have found on the internet the only real way to fix this is to send the monitor in under warranty for a fix/replacement.

Monitor (Sceptre X7G) powers up and the display cuts out after about two seconds while the power LED remains blue. Opened up the monitor and found two of the four 470uf/25v capacitors had leaked a thick brown substance all over the circuit board.
Will replace and report.

2 Capacitors broken within my hp 1530, and now it's working perfectly (0,70 €)

I had a similar problem with a Sceptre X7G NagaVI monitor. At first, the monitor would rarely come out of standby, requiring a reboot of the computer. Eventually, it wouldn't display anything and the power light would flash red and blue. A call to Sceptre's service department was no help, since they told me the monitor was out of warranty and it would be cheaper to purchase a new one than have it repaired.
I checked the power board, and there was a pair of capacitors that were swollen and tilted. I replaced the pair at a cost of $1.60 and it is working like a charm now.

Was on the phone to Xerox Tech - they say it's a known Fault - and will cost £55 to fix.

Try, Looking at the Monitor propties to see if it is a configuration issue.Thats if the first problem solving that you read above does not work. By Lady1

Try replacing cable from monitor to computer, there's a good chance this is cable related. try connecing another cable from monitor to computer, and check if there are any broken pins in any of the outputs.

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).
