Our 35" Toshiba tv has a crakling noise. It's almost like there is a bad wire, or it's picking up outside interference. For a while, we thought it was truck cb's or something like that.
We have Direct TV. They said everything was ok on their end. They said it must be the tv.
The tv is about 15 years old.
The picture and sound are both fine.
Any advice would be appreciated.

Is the sound coming from the speakers or from inside the tv, like an electrical arc? It could be the high voltage wire going to the picture tube. Do not attempt to test this yourself as there is many thousands of volts on that wire even when the tv is turned off. That wire attracts dirt that may be causing it to arc.

Most likely it is the Color Wheel Motor making the noise and the Optical Block would have to be replaced to fix the problem. If it is out of warranty, I would still call Toshiba to see if they could help you with the cost of the repairs. They could also refer a Service Facility near you to do the work.
I hope this helps,
Sounds like you have a bad flyback Transformer...Crackling is high voltage leaking. I would quit turning it on and replace the main board in the set if you are good at soldering you can replace the flyback transformer but cost wise it is easier to replace main board. 20" might not even be worth the repair.
your problem is a stand-up printed curcuit pcb it has several mof those small surface mounted caps that always goes bad and the # on the part is SBX1981or SBX1981-51p its part # is 874213400 its about 11 to 15 bucks . Dont try to repair the part as the pcb is eaten up from the caps leaking all over it. Good Luck
