Television and Home Theater

I have a 20" Phillips flat-tube CRT SDTV with component inputs and its been excellent for the year that I've owned it. However, there are a few very small black specks that appear to be beneath the glass of the screen. They're very distracting to my meticulous eye and I was wondering what some good suggestions might be.

Would it be convenient or noob-friendly to take it apart and clean it off? Would a TV repair shop clean this up for me for a reasonable price?

Any ideas or suggestions would be greatly appreciated.

I have a zenith integ model iqb6om90wa has worked fine since 01 but from repeted movings the picture got a little blurry at bottom right. Made a few phone calls to repair shops they said most likley convergence adj. The est.s were between 250-550 so I tried to adj myself have made some progress but without some stationary lines to adj to have ended up making it worse. I was told that I needed a test pattern dvd and some new advice on where to start.

have recently purchased mirai 32" lcd, humming sound coming from speakers, even when there is nothing  connected into the television, when a device is connected the humming gets worse, does anyone have any ideas as to why this happens
