    I purchased this TV from a friend that was loosing her house, the tv always worked fine at her house and it worked fine at my house for the first week I had it, then one day I turned it on and after about 20 minutes of wathching the tv it went blank but the sound still worked. I removed the back of the tv and used an air compressor to blow out the dust, thinking this might fix it and it did for a few minutes then it went black again. Ive read that this might be the doubler board but that it may not have to be replaced. I need some help if any one can please give me some info I really cant afford to pay $800 that is what I hear it might cost to have this fixed

Finally got a tech to come out to the house ($99 to diagnose).  He determined it was the Doubler Board.  Got a quote from this company to repair it for around $800.  I was able to watch over his shoulder.  The board is really simple to replace.  I just need to find it.

Since you did not provide the make and model, you will have to pull out the manual and check the settings. It may provide you with a setting change for the background color. Perhaps you can connect it to a computer, open an new blank document and project the blank image to get your white light.

Does the input menu appear on the screen when you press input? If so its probably the IC Regulator 9v supplying the video board. If the green light on the front is blinking then powering off it is one of the 7 capacitors and you should just replace them all, 30-35 bucks. If the power stays on and its just your video isnt coming on(audio as well) it is the IC Regulator. Mine called for the part - BA09FP IC REGULATOR 9V It is about half the size of a pinky nail and located directly behind the video input board in the back of the tv. It has two prongs on the left side and one wide tab on the right. It solders directly to the top of the board and not through it. It says BA09 on the chip. This fixed the problem for me.

Did this happen all of a sudden? If there is no video/ audio input on all the inputs then you will have a failed front end. You will need proffesional help.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.

Samsung tv goes blank to a blue screen, has audio no video


You are probably on an aux or video input, or the video cables are shorted.

Wii Start but the game didn't start, screen went black


  • Is this your first time hooking up the Wii console or have you moved it to another TV or VCR?


  • The AV Multi Out plug that is included with the Wii will allow you to connect the console to most televisions or video cassette recorders (VCR). First, look at the back of your television AND your VCR and see if you have colored holes label "Input". Though most TVs have them, almost all VCRs do as well.

    • Audio/Video (AV) inputs are located on the front or back of the TV or VCR.
    • They are smooth silver posts with the inside showing a color, usually red, white and yellow.
    • Look for inputs marked Audio and Video IN.
    • The image on the left features stereo audio inputs. Some televisions have only one audio input. Click here for help setting up a mono audio connection.
    • Do NOT connect your system to anything marked OUT.

  • My experience shows that the majority of these issues can be solved by double-checking your connection and finding the correct Input Select for your TV or VCR.


  • If you have verified the connection is correct, and are still receiving a blank white or blank dark screen when powering on your Wii console, then the problem is likely with the system and it will need to be repaired.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
