Tv shut off came back on with large screen

There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

Hi.

No you shouldn't need a new TV, all you need to do is reset the video settings, follow the guide below >>>>>

1. Make sure that you have only 1 type of video cable connected between your PS3 and your TV or monitor, an HDMI cable is optimal. If you have multiple video connections the reset sometimes does not work.
   
2. Make sure that your TV or monitor is turned on and set to the proper input for your PS3.
   
3. With your PS3 in standby mode, turn your console on using the front power button and hold the button down.With the button held down, You will here one beep when the console first turns on, and, after about 4-5 seconds, you will here a second beep. When you here the second beep let go of the button.
   
4. If you watch the screen you should see it flicker once or twice and then your system should boot up and go to a screen to confirm your video settings. Simply confirm the settings and you should be able to resume playing your PS3 as normal.
   
5. If your system does not boot up and give you the confirmation screen for your video settings, then you should shut the system off and restart the system as normal. This will usually finalize the reset of the video settings.
   
6. If your system still is not displaying video then please repeat steps 1-5 again. It is unlikely but, you may have to reset the video 3-4 times before it works with your console. The reason for this is unknown.
   
7. The procedure to reset video ,on your PS3, should be complete at this point and you should be back up and running as normal.
   

NOTES: PS3 "slim" models are always in standby mode when plugged in. PS3 "fat" models must have the rear power switch turned on. If you are only using the composite video cables, then there will be no confirmation screens for your video settings.



Regards.

.sharp X Flat Slim TV model number 21G-FX35 i lost my password please tell me its master password

After cleaning my screen from my kids sticky fingers and having it outside in the cold .. around zero my screen stopped working. The screen displayed okay but the calibration was so far off I could use it. I played with it for a while until I got it to work again.. First I recharged it. Then tried to just do a shut down which didn't work cause you have to hit the yes on the screen. Then I tried the reset button, then tried the reset and holding the power button then plugged it in the usb port. Did a shut down, it reassessed life and started working again. Better than when I bought it.. from Kijiji.

Yeah, seen that more times than I shoulda in the last 4 years. The red picture tube has a cathode to heater short. That means it's no good. That red picture tube is no longer availible. But all is not lost. There is a company that rebuilds those tubes reasonably. Most reputable tv shops will know this. The ones I've done cost around $450 out the door. One minor hitch is that with all the shipping involved the job usually takes about three weeks. That can be expidited but then the price goes up.

Poer supply is the cause of the shutdown and would need to be replaced. These cost around $150 bucks just in parts the labor you would need to find someone that knows just what there doing or you could wind up into the hundreds, Thanks

This is due to bad caps read here what a cap is www.badcaps.net see you tv is getting hot as normal but the caps cannot stand it any more thus shutting the tv down. The bad caps would be more or less in the power supply unit of this TV. So you can buy a new psu or get it repaired by a expert.

This is how I got mine to work after weeks of struggling just trying to find a new remote (hisense is really hard to contact....).
1) Turn the TV ON. unplug the tv while still ON 2) hold down the "menu" button on the side of the TV and plug it back in. keep holding it down. the TV should turn on with the menu popping up. use the Vol <> keys and Channel <> keys to navigate the menu. go to the Vchip menu, and play around. I'm not sure what ultimately worked, but i changed the Vchip password to 1111, turned the reset menu to "on" and played around with the ratings settings (turning most of them to "u"s etc).
I went through this process several times and finally, the black background behind the menu turned to static. I played around with the channels, and the TV was unlocked. I turned the TV off, and then on again, and the channels showed up normally (no static). and it was no longer locked. I had to do the unplug thing several times, and was getting really frustrated looking for an "unlock code" in the manual (it just says press the button on the remote. so it was not really helpful).
But really, once you can just get to that menu you've made some progress, and just keep playing around with it until something works.
Best of luck!!
