SOURCE: goodmans flat screen TV.Blank screen

If it is a LCD TV, and there is a faint picture, it is probably the backlight or inverter board (probably the latter). This is a common problem (especially with PC monitors).
Do an internet search for your model and inverter, you may be able to replace it.
Make SURE you REMOVE the power lead before opening the set !!!!

SOURCE: TV No Picture

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

SOURCE: flat tv, sound but no picture. have tried

I had one that had a black screen and fixed the problem by repairing the inverter. When I opened the unit I looked at the capacitors on the inverter board and found them swollen. I looked at the bottom of the board and found that the fuse had opened up. The caps were a cheap quality low temp variety 150uF at 25V I replaced them with 330uF 25 volt 105C caps. I then replaced the 2.5A surface mount fuse with an axial 2.5A pico fuse and the TV worked beautifully.

Monitor goes black - green light stays on


My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.
  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer
  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

No picture on the screen. Sound is working


This problem is hard to pinpoint as there are so many variables.
If I could ask you a few questions first: -What is the model of the display?-What other components are hooked up to it?-What cables are connecting these components to the TV (e.g.. HDMI, Component, Composite etc.)?-Are you using an external sound source (stereo) or the TV speakers for audio?-Do you see and indicators or the screen when you turn up/down the volume or change inputs? This is of course using the Samsung TV's remote.
I would try these things though:
1. Turn the TV off, unplug it from the power source for 30 seconds.2. Check the cables are all plugged in firmly and correctly.
3. Plug it back in and turn on the TV. Still no picture?
4. Try changing to another input (e.g. DVD, VCR, XBOX etc if you have one)3. Check on the Tv's remote to see if there is a "picture mute", "blanking" or similar button they may have been accidentally pressed. When you press it again, you will get picture back. If there is no button and still experiencing the same problem after checking all these things then you may have a fault.

Mute is on when I turn my vizio on. How do I


The OSD consists of several menu options: Picture Adjust, Audio Adjust, TV Tuner Setup, Parental Controls,PIP Set Up, or Special Features. When in the TV menu, select the Audio Adjust and make sure the mute is off. It may be worth checking the manual which is avialble from: http://www.vizio.com/downloads.aspx
