The unit should be under warranty. What you're describing is not normal and I would attempt to get a replacement from the place of purchase or take the unit to an authorized repair center. Below is the Philips support page for your unit. You can check warranty status as well as request repair.

Had same prob;em. Replace main board and now works just fine. You need
to take the back off and under the metal cover is the main board. The
part number should start with 3320-xxxx-xxxx. You can purchase the
board from Vance Baldwin. vancebaldwin.com sign in as a guest. I will
warn you the cost of the board is high.

It could well be the accumulation of dirt/dust behind the buttons causing them to stick. If you are able to carefully remove the board that the buttons are located on and use a cleaner that will de-grease at the same time. Be sure that everything is dry as can be before re-assembling and then check if the problem persists. If you are not capable of doing this trust a competant technician. Hope this helps.

Remove batteries from remote, and test again the touch buttons on TV with remote batteries out. This to exclude the possibility that remote has a stuck button.
If the problem persists , then it is probably a faulty IR board on TV (the one that gets IR signal from remote), or a faulty touch button switch.
