SOURCE: service menu mode

You should first check the output voltages comes out from its main power regulator section; and to rectify the cause of this shut down first. Then only, there is any need to enter its service mode. If you're sound in electronics, and wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window. Service mode entry, adjust and exit procedure to many brand TVs are given in detail.

My tv is changing channels it self


The memory IC to your TV is faulty. Check and replace it. This is an eight solder terminal IC, can be located very near to main system control IC. Even though physical size to this IC is so small, function to it in circuit, when the TV works is great. You must have thofough knowledge in electronics to do this work, because, you might have to enter its service mode option to do some adjustments. This work is very skilled one, as service mode option window, and normal user window are entirely different to each other. Adjusting wrong data value to service mode options might make the TV irreparable, and irresponsive.

42hp66 toshiba will not change channels sits on channel 27. I do not have cable but the signal feeds other tv and this one was working this morning


I would say this has a software issue with the Eprom ic, I would try to get in the service mode and reset it to factory settings ( Google your model for service mode )
Failing this it will probably need a replacement av main board.
