    We have the same problem, with tv shutting down, and going into standby mode, after a few minutes. Have had it since 2002, and it is a philips, model no. 29PT6361.

    TV shutting it self off

    MEHMET Mar 11, 2018

    Sharp smart tv shut down by itself after 5 minutes if it rest a long time. Then shut down after some seconds.

    Tv used to shut down by itself after 30min when I bought it as used and i opened big holes on tv cover on behind. then the time delayed up to 3 hours.
    But now it shut down after 2 seconds if tv rest 10 hours the time is initially 5 min then 1-5 seconds.
    I changed 7 pieces capacitors but nothing changed. The power card number is HLL-4255WJ
    And it has 12v and 16v output, 12v is always constant. On 16v output, there is 19v when tv standby, when the tv is working it drop to 17volt.
    What is the problem?

Magnavox television won't stay on

I know this is going to sound strange but I have something to check. If you have LED lights in your house turn them all off. When they are off turn on your TV and see if your TV stays on. Yes, there could be many problems but this one is cropping up quite a bit. If this does not work then you need to take a look at the power supply board.

Philips Magnavox 32MT3305 keeps shutting off with relay clicking. The green power light stays on but the picture and sound go out right after the orange status bar goes away. If the channel up or down...

the relay is the safety protective device..sometimes a defective component or something. maybe an overloaded power supply might caused this before any thing could gets worst..the relay will shut the unit..

Magnavox # 37MF231D

that depends on the value of the television and the cost of replacing the power supply and connections.
Most likely you have a short in your power supply or other connections causing the tv to protect itself by shutting down. You can check with our Repair Service lookup icon for a repair service near you.
Before you call them you may try unplugging your unit for 30 minutes or so and plugging it back in.

My TV keeps shutting off

Tvtek is on the right track. The remote will not solve the problem. Sounds like a voltage regulator in HV circuit if it only lasts a few seconds. If it stays on for a couple of minutes, beam limiter cicuit is pushing to overload and shutting unit down. Magnavox set not hard to repair, but a 27" set is not cost effective to repair either.
