How to remove silver caps from the bottom on sceptre monitor ?

It may have power supply problem due to bad DC filter caps, bad backlights inverter circuits, and worst case will be the lamp assemblies.
You need to open it up and check the caps in the power supply section first.

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Look for bad caps with domed tops, similar to the 17" version here: http://s807.photobucket.com/albums/yy352/budm/Sceptre%20X7G/

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
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). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Start looking at the power supply for bad caps, see some example of a couple yeras old monitors that failed due to cheap caps being used: http://s807.photobucket.com/home/budm/allalbums

I have a bad power supply in mine as well. trick to opening it was popping off the silver caps on the base to remove the base. then using 2 bladed screwdrivers carefully pry the front plastic bezel off the back. there is no glue just locking tabs.

Your monitor has 3 or 4 blown caps right next to the power plug. They are CapXon 470uf25v. Just open the back and remove the power board, desolder, and replace the 3 or 4 caps put it back together and it should go back to working. This a typical problem with the Sceptre gamer, HP1706, and the HP1903. And guess what they all have the same caps blown in almost the same place.NOTE: When seperating the case the power led is glued to the front frame. Take your time if you rush you will break a cable wire or plug.

hy,
usually the capacitors on the inverter board for the backgroundlight
should be replaced.
good luck

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).
