Guessing you have either fixed this or tossed the tv, but I thought I would post my experience with this issue.
Came back from short vacation to tv that would not turn on. When I plugged it in, it started making a high pitched fast beep noise shown in the video below. Only the lamp light would blink and then after a few seconds the standby light would come on and the process repeated. After doing a lot of research with no real answer, I decided to take a shot on the color wheel as the problem. The TV had been making a high pitched whinning noise for some time, and I had read one post stating the tv might not power up if the a color wheel issue was found by the controller.
I ordered a new wheel from samungparts.com and spend a couple hours putting it in, although most of that time was cleaning up dust, what a mess inside. After reassembly, all is fixed! No more beeping, tv comes on and its quieter than its been in a long time.
Now I only have to decided if I will replace the cooling fans to make it even quiter.
Sad to see this forum is dying out, I guess most owners have moved on by now. I've used fixes and information found here in this thread to fix several problems with this tv. I keep kinda hoping the next problem will be fatal so I have an excuse to get a new one, but oh well, I can't just let it die.
Hope this post helps someone, Thanks to all the pevious posters who helped me.

I did not see an update from Black | Dragon as to what this beeping was or how to fix it. Does anyone know what this might be?
