It sounds like the circuit board that controls the channel/volume/power/etc. is shorted out. You'll probably have to contact the manufacturer and see if the set is still under warranty. If not, contact a local TV repair shop and tell them what the problem is and if they can give you a quote over the phone to fix it. You can then either get a second opinion from another repair shop, or weigh out the price of a new TV against the cost of repair. Hope this helps...

I have a 50" philips magnavox tv that changes channels on it own and turns itself on frequently. What is causing this issue?


Do you live with someone who likes practical jokes; even silly ones?

There are a number of companies that make remotes that can mess with someones TV or other remote devices.
I have a watch, as a gag, that will self program its remote to operate any TV capable of this feature. With this watch, I can change channels, power status and even reset the TV to factory default state.
Next time this happens, look behind you.

MENU SCREEN POPS UP, TV CHANGES CHANNELS, TURNS SOUND DOWN


Yes. Its probably a stuck button on the TV's front panel. Try pushing or wiggling each button on the panel. It could be the channel up/down buttons or volume up/down, menu, etc.

When there is a button that is making slight contact, it keeps the microprocessor busy attending to the command its erroneously receiving from the offending button and may not allow other functions to work when this occurs.

It doesn't matter which button is stuck, any of the symptoms you describe can happen.

Have installed a brand new Gold Plated Scart Lead (original Scart was probably defective). Incidentally this is not a Projection TV but an attempt to prolong the life of an old-fashioned Cathode Ray Tube.

Echostar t101 fta digi box retuned and lost bbc1 bbc2 itv and channel 4 all to channels 801 and above any help and advice would be very kind


This is due to NIT in DVB-T transmission

Digital UK estimates that "only 1%" of Freeview receivers are susceptible to this change - technically, the introduction of a multi-part Network Information Table within the digital data.

The effects on some of those STBs and VCRs are plainly malfunctions, such as abnormal channel numbering e.g. Channels may be listed, but they're assigned to all the same number or assorted incorrect numbers. Alternatively, no pictures are seen, despite all channels having high ratings for signal strength.
