    I have the same problem, Vizio GV47LF. Heared a pop and screen went to grey with no audio. Happened 30 days after warrenty expired.

    Referred to ITI for repairs, waiting for them to return my call.

    ITI phone number: 1-888-248-2708. Will try to post solution after repairs are estimated or completed.

The wiring might be bad or broken or you might have to replace a part called the power board

What needs to happen to view picture? Screen is currently black.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Could you please tell me how to reset my tv? I have a blue screen


What should I do if my TV screen turned black, blue, or gray? print.png Print try this.

Proceed with the troubleshooting steps below only if you're seeing:
  • Black, blue, or gray screen
  • "No Signal" message without the DIRECTV logo
Note: If your TV screen appears "frozen" or you're seeing wavy lines or overlapping images, try this.
Solution 1: Check that your TV is set on the right input
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number1_icon.png">Turn your TV and receiver off and back on.
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number2_icon.png">Using your DIRECTV remote control, press the TV Input button to cycle through TV inputs (Component, HDMI, etc) until you see a picture. If nothing happens when you press the button, try programming your DIRECTV remote to control your TV Input and try again.

Note: You can also try changing the TV Input using your TV remote.
[img border="0" alt="Image" src="http://www.directv.com/cms2/global/icons/sm_cl_blu__number3_icon.png">If you're still having issues, check the cable used to connect your receiver to your TV.
Still not seeing a clear picture?

Solution 2: Reset Your Receiver
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number1_icon.png">On some DIRECTV receivers there is a red reset button located inside the access card door on the front panel. Press it, then wait for your receiver to reboot.

Note: If you cannot locate the red reset button or your receiver does not have one, unplug the receiver's power cord from the electrical outlet, wait 15 seconds, and plug it back in. Then press the Power button on the front panel of your receiver and wait for your receiver to reboot.

Picture red can not fix


Step 1:

The problem you have is the grayscale tracking needs to be reset.
First, This looks like a philips tv. In order to set the grayscale tracking remove the back of the set. There should be rectangular shaped box that is marked screen and focus on it with 6 knobs coming out of it.

Step 2:

NOTE: DO NOT TOUCH ANYTHING INSIDE THE SET-YOU WITH BE SHOCKED! WITH THE TV TURNED ON, WITH THE REMOTE, TURN DOWN THE COLOR TO ZERO. ON THE CONTROLS I PREVIOUSLY MMENTIONED, THERE ARE RED,GREEN AND BLUE ADJUSTMENT POTS.

Step 3:

TRY TURNING DOWN THE RED UNTIL YOU SEE A NORMAL GRAY PICTURE. YOU MAY HAVE TO ADD MORE GREEN OR BLUE AS NEEDED. IF THIS DOESNT LOOK RIGHT ,TURN ALL 3 R.G ANDB ALL THE WAY DOWN, THEN ADJUST THEM UNTIL THE COLOR IS JUST APPEARING ON THE SCREEN, MAKE THE PICTURE AS GRAY AS POSSIBLE. iF THIS DOESNT WORK,YOU WILL NEED A SERVICE PERSON TO REPAIR YOUR TV.

Went blank sound and picture went off will not turn off with remote or tv button. I have to unplug it to turn it off. when i first turned it back on it was just blue screen now still having to unplug it...


Most LCD tv's having a lot of bad caps in the power supply ,that makes for really weird things happen, since they work like a computer during boot. For that 2-3 second "boot" the processor in the set checks for a combination of things and if those caps go bad in the supply the set will show a wide variety of symptoms.
Usually the set won't start for a minute or two and sometimes longer, after that comes some weird things like lines and what not and the set finally just won't come on period.
I could write a book about how simple fix like changing a few caps causes all kinds of phenomena..lol

TV will not turn on until I unplug, then plug it back in.


I have the same problem with my Soyo 32" lcd tv. Seems a lot of people do. Soyo went out of business, but I am going to see if it is the capacitors, like several people said on here.

I changed the batteries in the dish network remote and the screen went gray blue colored and nothing happens. Like I have no signal, all 3 of my other tv's in the house work. The remote seems fine the tv...


Look for a reset button on the dish receiver its usually located behind a panel on the right side of the box, may need something small to push it in. Hold for at least 10 seconds and let go. System should reset itself and rebroadcast.. Also if this does not work try unplugging the dish box from the wall outlet for about 3mins and plug back in.
