I have 20MC4306. Recently when you turn it off it turns itself back on. Also when you turn it on shuts off after 2 seconds. Tried putting in a video vhs then press play and wait few seconds and hit...

Sometimes when the TV recives a brodcast signal for a new update to the mainframes firmware, it will have to turn itself on to install/recive the update and aslong as it is connected to a power source it can do this. hope this helped answer your question. Have a good day :)

All TV's in house failing, a few at a time

Hey PNorris,

If multiple electronic devices are failing in your home all at once, I would probably first have to ask if your home recently experienced an electrical storm or major power surge of any kind.

Normally the effects of such large-scale surges are immediately noticeable - TV's and other major electronic devices may fail to turn on, fuses may be blown or circuit breakers tripped, and in some cases electrical wiring may be melted.

If nothing like this has happened recently, low-level power surges may still be a potential cause of this problem. When the motor from any large appliance (such as an air conditioner or refrigerator) turns on or off, it often diverts power to and from other electronic devices using the same circuits. This fluctuation in electrical current may result in low-level power surges to every connected device. While not immediately noticeable, these low-level surges can often cause the eventual failure of (and gradually degrading quality in) many audio/video components.

Typically, the easiest way to avoid situations like this is to make sure that outlets are not overloaded and surge protectors are used with every major electrical device in your home. For older homes however, replacing the house's wiring may be necessary. Homes that were originally built at the turn of the 20th century may not always have wiring capable of supporting the electrical needs of many modern appliances.

Ultimately, this means that in addition to contacting your local TV repair facility, you may want to also speak with an electrician. This is probably the best way to determine whether or not power surges have caused these failures, and may give you a better idea how to proceed.

Hope this helps you out.

Is there a tape in the VCR by chance?.
Usually what happens on these combo units is the VCR develops a mechanical problem which inhibits the whole thing from working or overloads the power supply causing it to shutdown.
The ones with the VCR underneath are difficult to work on as the cables to the VCR are so short you have to disconnect it in order to get it out where you can see what is going on, then work on a solution, put it all back together, test it, rinse - lather - repeat. Takes forever sometimes. Find a good VCR tech and talk to him nice and maybe they will help you.

Toshiba TV/DVD Combo Model MD14H63

I have the same problem with this model as Guest, who posted on 01/03/2008: power on, red light, immediate shut-off. The sticker on the television says it was manufactured in April 2007. I think there should be a warranty on it; I suppose I'll be calling Toshiba soon if it doesn't start working. Maybe important to note for any potential buyers, as well.

What do I do when my Emerson TV keeps turning off by itself?

I had the same problem with mine turning off after 3-5 seconds. After much research I found a suggestion that on some combo units the vcr part could have a power supply cutout if it is not working correctly. I tried to insert a tape and found that the tape mechanism would not accept a tape. I used a little bit of force and managed to insert a tape. I then played the tape forwards and backwards and the power stayed on! I ejected the tape and found the TV then worked just fine. The power has now been on for over one hour. I hope this give you another avenue to try and fix your problem.
