I purchased a display model tv that did not come with the base stand so I either have to find a stand or purchase a wall mount (which I don't want). I've called RCA to get this part and when I give them the model number they tell me that there are suppose to be more number/letters at the end but the back of my tv only shows L32WD12. I'm having a really hard time just trying to get the base stand for this tv....any suggestions
