Question about Elo 15" Touch Monitor
I have 3 ELO Touchscreen monitors that are not responding to all of the touches. How do I go about adjusting the sensitivity on these monitors? It only responds to finger press not finger nail or pen. Should it respond to all of these? HELP!!!!! These are in a restaurant and it is making for a very bad situation.
You probably have a capacitive screen, it only responds to finger press. You need a resistive screen to be able to respond to finger, nail, or pen press.

Your problem lies ion either your back light inverter or in the backlight tubes ( bulbs) which are embedded in the LCD display. The display has 4 ccf tubes inside of it that provide the backlighting. if any of these tubes are bad the backlight inverter will shut off after about 1 second. Because there are 4 of these tubes inside the screen you may not notice ( brightness wise) if 1 of them is out.
You can buy another backlight inverter( about $70.00 US) however, from my experience that would be a waste of money. Unfortunately, I think your problem probably lies in your LCD and the backlight tubes are not replaceable.
Hope this helps all who have this problem.

When LCD's "turn on" momentarily before going blank again it is an indication that the backlights have worn out. Cold Cathode Floursecent Lamps (CCFL's) have a limited amount of hours which they can be in operation for before the mercury vapor in them breaks down (or leaks out). When that happens the backlights no longer look like a load the inverter (device inside the monitor which turns low voltage into high voltage) is programmed to look for, and long story short, the inverter does not keep the lamps illuminated because of this being a safety setting, if the load no longer looks like what the inverter is looking for, it could be sustaining an open arc which then leads to extremely high temperatures, and a possible fire. The flash you see is the "firing voltage" (I think that is what it is referred to in the industry) which is a very high voltage pulse used to create the arc between cathodes in the CCFL, creating the arc takes a much higher voltage than sustaining the arc, so even if the inverter successfully creates the arc and lights the cathodes, it quickly doesn't look like a proper load and then inverter quickly turns off to prevent damage.
In essence CCFL's are usually the weakest link in LCD monitors as far as what is most prone to failure, technology has been improving, but if you keep your monitor on all day long at full brightness, never shutting it down, don't expect more than 3 years out of it :( Some brilliant LCD manufacturers recognize this problem and even make the backlights replaceable!! What a novel concept!!! But due to price gouging, the replacement backlights are usually sold for a premium from resellers, better option than the majority of LCD displays which have the backlights so integrated that you end up destroying the LCD and introducing contaminates in the process of "reviving" the display...
Your best bet if the backlights are in fact shot, is, if you are handy with a soldering iron, get the LCD apart, get out the backlights (there are probably four in there, possibly 6) measure the diameter and length, and look on eBay to see if someone is selling the particular CCFL you need-- that may be the cheapest route if you are out of warranty...

Your might need touchscreen configuration. Please follow the
If you are asking about the touchscreen of your desktop PC then I would suggest you go to control panel and look for ELO Control Panel where-in you will be guided to touch three targets on the screen. Then Verify the touchscreen if it is working and aligned properly. If you need to align further then go back to the ELO control panel and repeat the process.
