TV turns off and on

After about 30 seconds the tv shuts off, then back on, then back off, continuesly till we automatically turn it off. Sony came out and upgraded the software and that did not help. The tech did not know what could be wrong. Can you help?

Did they replace the lamp? The lamp in a Sony will cause int. power loss.

When I turn on my Sony TV, ti stays on about 30 seconds then shuts off, What do you think is wrong?

Do a Power Reset.
1. Turn off TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.
If issue persists after doing the steps, reset the TV to factory default settings.
1. Turn on the TV.
2. Using the supplied remote, press and hold the UP arrow button.
3. While holding the UP arrow button press the POWER button on the TV itself.
4. When the TV goes off, release the POWER and UP arrow button.
5. The TV will turn on by itself and the initial setup screen will be displayed. Just follow the on-screen prompts to finish the setup.

My Sharp LC-42SB45U takes 15 min to an hour to turn on. Also, sometimes picture blacks out for 10-15 seconds. Any suggestions? Pat Courson

Have same problem. Not the proper fix though I found that taking the back off and heating it up with a heat gun for 30 seconds to 1 minute and tv works fine till you shut it off over night.Maybe someone can offer a solution with that in mind. Pretty strange

Code number to program my bell remote to this tv

01768,11034,11265, 10178, and 11748.
Or you can:
1. Press "TV" button
2. Hold "P" (program button) till the "TV" button flashes once then twice
3. Enter 9 9 1, and the "TV" should flash twice
4. Aim the remote at the TV and hold the Power button down for at least 3 seconds. (Remote automatically goes to first code but it probably wont work so go on to step 5)
5. Press CH+ repeatedly till the TV shuts off and stop immediately!
6. Hold "P" for 2 seconds
7. Hold "Select" for 2 seconds
8. Hold "P" for 2 seconds
9. Hold Power for 2 seconds and TV should turn back on

Vizio M470NV just purchased, while watching TV it turns off with the Vizio light blinking between orange and white. Can not turn back on !! I have to just wait for about a minute then tv turns back on by...

I have the same issue on my Vizio M470NV. I called Vizio and they told me it is a self diagnostic test that is shutting down the TV automatically to protect it. They said they are working on fixing the issue with a firmware update that will be pushed out automatically if you are connected to the internet. No ETA given on when that would happen. I called them on the 3/14/11 and my TV is still shutting down randomly.

Unable to Power On or Off the set

Symptoms / Customer Description
The symptom may occur while the TV is ON or in Standby.

1) If the problem occurs while the TV is in Standby:
The TV will not turn on via the remote or power button located on the set however after AC reset (i.e. unplug the TV for at least 30 seconds from the AC source) the TV returns to normal operation.

2) If the problem occurs while the TV is in use:
You may lose the ability to power off the TV or switch the video inputs however channel changing, adjusting volume, or accessing the menu may still be possible. After AC reset (i.e. unplug the TV for at least 30 seconds from the AC source) the TV returns to normal operation.

Sony has designed the BRAVIA Televisions to be CUSTOMER Software Upgradeable and therefore Sony will not pay a service claim on any issue resolved by a software upgrade. If a customer requests an update please refer them to the following website: If the unit requires the update, you may enter the customer's information in the website and a USB device will be sent to their address.
If a customer does not have access to the web please have them call the Sony Call Center Support line: 1-866-210-6333

If a customer reports either symptom above request that they unplug the set from the AC wall outlet for at least 30 seconds and then plug the set back in. This will reset the TV and it should work fine for several months. If resetting the TV does not resolve the issue the customer has a different problem and a service call by a technician may be required

Hi, Lamp of TV getting weaker and requires replacement. This shut off by itself will increase day by day until you put new lamp in TV. Always Buy Sony original lamp and avoid aftermarket/ cheap lamp for TV safety.

I have the same television. Mine would shut off and turn back on every 30 seconds. Even though the LAMP light wasnt coming on in the front of the set, I replaced the lamp with a factory Sony lamp and have had no problems since. The sets picture is beautiful and I have had no problem since.
