I would repair this set in the house, yes! That set is a big old monster to carry around. The tech probably wants to take the set to the shop because they make more money that way. How do you know the tact switches are bad? What are the symptoms of this TV set?

Is the TACTILE Momentary switch really bad (no clicking feel to it?)
The board is called Function switch PCB aseembly. You may be able to find the switch at WWW.MOUSER.COM, WWW.DIGIKEY.COM
You can try looking for PCB assemblies on EBAY.

What is the symptom anyway?

Power button doesn't work
Not very likely to be the switch itself, the switch is a tactile momentary switch, more likely to have failed power supply due to bad caps just like the rest of failed monitors here, check to see if your adapter is putting out 12vdc, then we need to find out if it is getting 12vdc all the way to the main board and the inverter board:

Toshiba television will change from tv/video mode to
I would check to see if the Input button is stuck on the front panel of TV. If it is not stuck then it is probably still bad. Tactile switches are notorious for failing in this manor. The only real fix if it is not stuck down is replacing the switch.
