Remove all batteries from any remotes in the room. Unplug the tv. Wait several minutes and power it back up. Use the controls on the unit to turn on etc. If the unit still changes channels you probably have a tact switch on the control board which is sticking or shorted out. Unless you have dealt with this before you will need a tech to fix it but the good news is it should not cost very much. Let me know how you make out.

Sounds like you may have had some fluid go from the screen to the buttons on the main board...like Windex or something, and is causing a short in the buttons. The only way to repair it is to have the main board removed and cleaned or have those buttons replaced.

SOURCE: TV keeps changing channels by itself

Either the channel up or down buttons on the tv are most likely stuck.

Here is th elink to Philips support page fro your TV.
Turn on the TV, if it is working you should see the light of the back light lamp. If you are changing channels and hear audio from different channels it is a good bet you lamp is open.

You need a professional.
Your TV has "lost is mind"

Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.
