My stand will not go back so I can attach the base...please assist

No.
Stand or base on any model of TV should be removeable without taking the back panel. How to Remove Pedestal Stand from Your TV YouTube

For the ASUS VH197D LED Monitor, turn it upside down so you are looking into the base of the stand. Squeeze the plastic tabs to unlock the base and pull. This will remove enough of the base to make it wall mounted and you can quickly attach the base if so desired. If you want to permanently remove the base and stand, remove the two screws that are now visible after the base is removed and pry out the plastic stand. This will break it off at the hidden screws. You will be left with a short metal stub that can be folded in.

depends on what TV you have. Most TV models i've dealt with, you need to remove the whole back of the TV and take the base out. Some smaller LCD monitor bases like Dells are attached only by a latch. Some bases are held together by 4 screws where the VESA mount would go.

I generally go to Ebay when I need to replace a part or find 'hard to find' items. You can find monitor stands on ebay for a reasonable price. You just have to make sure that the stand will work with your emachines monitor. All you have to do is look at the back to see how the stand attaches to the monitor and look for the same mount type. Below is a link to an ebay listing for 15 inch monitor stands.

You can also contact ebay by chat by following this link and ask if they have stands available for your monitor. There are none listed on the emachines site, but that does not mean that they are not available. The link to the Emachines contact page is:

These are two suggestions for finding a replacement monitor base or stand. I hope that you will be able to located the proper stand from these resources.

If I can be of further assistance to you, please let me know.

Check the tv back cover at near around the base stand area.Lacate all screws near or at the base stand,spray some WD40 in each screws holes and wait like around ten mins.Take a Philip screw driver take out all the screws out in the srews holes.Take ur hand slicely push it foreward and pull it back.Now u should have no trouble taking out the base stand.

On the back of the set you will see 8 screws just above the stand; remove the screws
and gently slide the stand out. Wiggle it alittle and the stand will come out.
Remove the metal tab you just pulled out by removing the screws at the bottom of the tab (attached to the pivit joint) place the tab back in the bottom of the set( same place you removed it from) and re-install the screws ( don't over tighten them). You are done.

I had the same trouble with this set and the tech support was of no help. Good Luck.

I just repaired a 26" in which the stand came off after I took the primary panel off in the middle of the back then the screws were visible that Olevia is talking about. You might have a different style but it does come off.
