Most likely the TV has a power supply related problem. The most common problem are the power supply for the screen itself. Most manufactures call it a Backlight Inverter Board. My Emerson TV had a bad Inverter Transformer on the all in one Power supply/Backlight Inverter Board. Something you may want to look at for your problem. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

PS3 Has no Video - Simple fix!


When you attach your Play Station 3 to an HD TV through an HDMI port, the Play Station 3 will ask you if you wish to switch to HD Mode.

However, if you decide to move it to another TV that is not HD compatible, you will get no picture because the Play Station 3 is “stuck” in HD (HDMI) mode.

Follow these steps to resolve your problem:

1. Turn off the PS3 so it only shows a red light. You can hold the power button on the front until it goes into standby. To be sure, flick the power switch on the back of the Play Station 3 off and then back on.

2. Make sure your Play Station 3 is connected to your regular TV (not HDTV) with the standard video cables.

3. Press and hold the power button until the screen "flickers" and then immediately release. This should reset the video settings.

4. Wait a few seconds, and the Play Station 3 (PS3) logo should appear.

If this does not resolve the problem, follow these steps:

1. Turn off the PS3 so it only shows a red light. You can hold the power button on the front until it goes into standby. To be sure, flick the power switch on the back of the Play Station 3 off and then back on.

2. Make sure your Play Station 3 is connected to your regular TV (not HDTV) with the standard video cables.

3. Press and hold the power button on the front until the Play Station 3 beeps and then turns off again. This should reset the video for you and you can turn it back on after this.



That’s it! You can play your Play Station 3 again!

I connected my playstation 3 to another tv and it


If you attached your PS3 to an HDMI capable TV it asks you if you want to switch to HD Mode.

However, once you attach it back to a regular TV you get no picture.

Follow these steps to resolve:

1. Turn off the PS3 so it only shows a red light. You can flick the power switch in the back then back on again.

2. With your PS3 connected to the TV and the TV on, press and hold the power button.

3. Hold the power button until the screen "flickers" and then immediately release.

4. Wait a few seconds and the PS3 logo should appear.

Toshiba 62hx94 cant shut off closed caption have comcast cable How do I turn off closed caption on my TV. It suddenly turned on.


if the tv is not hd then the control is on your tv.
However if the comcast box is an hd box do the following;
Press cable, then power and then with 2 seconds press the red menu button to get the hidden hd user setup menu. You may have to hit the menu button multiple times to get the menu to stay up on the tv.
Next go down to closed captions which is probably enabled, and hit the left or right arrow key to change it to disabled.
Then press the power button twice to turn the box off and back on.
