Volume or channel button won't control menu features

SOURCE: Remote doesn't work

According to Mintek support you should unplug your set for 30 minutes which is a reset/rebooting process. Then plug it in and hold the DVD eject button for 5 seconds [at least]. The DVD should eject unless there is another problem. If it doesn't eject then call Mintek support at 877-646-8358 for help. They told me you have to send the TV to them and they'll send a new one. If you have to do that then make sure you tell them you want your DVD returned when they get it out. Good luck.

Is the Remote you are using an original factory supplied one from Philips?
If NI, then get one. You could ask the local Philips / Magnavox dealership, tho I have my doubts, from the age of the TV. If the dealership has one, yopu could borrow it for amn hour or so. Then use it to go to Menu>SETUP> DEMO or MENU>DEMO>DISABLE and disable the Demo function.
Otherwise, as you said, Out Front of the House on Garbage Pick UP day.

SOURCE: Why does my RCA TV cycle through channels on its own?

this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t

I have seen broken board inside. Have you ever pushed the front panel? If so, the board behind the control is cracked. If you are a tech, open and solder. If not, take it to a service center
