TV comes on and goes off by itself

The TV will go off for no apparent reason. Sometimes it has to be turned back on with the remote and sometimes it immediately comes back on. The set will also turn itself on in the middle of the night. I have eliminated remote malfunction.

In order to determine whether it is the TV itself or something in the room that is causing the problem, place an object in front of the infrared eye on the TV. This is usually a transparent red plastic window on the front of the TV somewhere. Verify that it is covered by trying (and hopefully failing) to use the remote. If the TV continues to turn itself on and off, then it is the TVs internal circuitry. If the behavior stops, then it is something in the room. One of the more surprising causes for behavior like this is sunlight hitting rotating ceiling fans -- the light reflects off the fan at just the right frequency to fool the TV. I mention this so you don't limit yourself to only thinking that it must be either the TV or the remote.

I have a Toshiba 32" xv555d tv. The power comes on when I switch it on, but only for a few seconds. The red light fades and tyhe poweer goes off.

You seem to be experiencing power issues with your Toshiba XV555D TV, where it powers on for a few minutes and then turns off. Such behavior can occur for a variety of reasons. Here are some troubleshooting steps you can try: Power sources and cables: Ensure that the power source is stable and that the power cord is properly located between the TV and the outlet. Sometimes an unstable power source can turn off the TV. Power Cycling: Unplug the TV, wait a minute or two, then plug it back in. Sometimes this can reset some internal features. Remote control and buttons: Make sure that any buttons on the remote control or the TV itself are not pressed or inadvertently, as this can turn the TV off unexpectedly External Devices: If you have an external device (such as a game console, DVD player, etc.) connected to the TV, try disconnecting it and see if the problem persists . . . . Sometimes a faulty outboard can cause electrical issues. Factory reset: If possible, do a factory reset on the TV. This will restore all settings to default values and may help fix software issues. Check for software updates: If your TV allows, check for firmware/software updates. Sometimes updates can fix bugs and improve TV performance. Ventilation: Make sure the TV vents are clear and unobstructed. If it gets too hot, it can turn off the TV as a safety precaution. Hardware Problem: If none of the above steps solve the problem, there may be a hardware problem. This can range from a faulty capacitor on the power supply board to other factors. In this case, you may need to consult with a technician to have the TV diagnosed and repaired.

Volume pegs to max. Turns itself on. Goes to menu. Intermittent

This is becoz your Internal Remote control response program chip needs to be replaced! You need it to get repaired at nearest service station. Or it may be due to Your keys pressed continously from remote control. Check both the causes! then decide. It will help you!

Magnavox 42 LCD 42mf438b/f7 turns on/off by itself sometimes screen goes blank tv unresponsive to remote

I have exactly the same problem with a Magnavox LCD 42", very similar model 42MF437B/37. I don't have a solution. If you unplug the TV and plug it back it starts working, sometimes for hours, sometimes for less than 5 minutes, before it turns off again. Does anyone have any real solution?

Remote quit working.....tv comes on and goes off by itself at various times

Sometimes Buttons on remote control "stick" underneath the faceplate. It's possible the on/off button is jammed. A lot of times when a button is jammed the other buttons fail to work.

Could also be the reason you needed to replace the batteries with a button being continously pushed will drain the battery life.

Push every button on the remote and kinda wiggle each button while pushing to possibly see if its stuck.

Hope this helps.

Large black square appears on screen of my Insignia NS-15LCD TV.

Look for the closed captioning (CC) menu in the set up and turn CC off.

Hide the remote from the set for awhile and see if some sanity returns. If that's the case, service or replace the remote. (Check the batteries first...accordianman

Sony TV keeps flipping to Memory Stick screen by itself

My sony HD TV started automatically flipping to the memory stick screen by itself. I thought maybe the remote was malfunctioning so I took the batteries out of the tv's remote as well as the cable boxes remote. Still does it. If I hit the memory stick button on the remote to switch off the screen sometimes it goes back to TV screen and sometimes it doesn't. Eventually, it flips back to the memory stick screen. Is this a known problem for this TV? your problem in system control section check aft &tuning ckt &its voltages check for loose contact in above ckt check tuner thanks
