My tv video is turn off but sounds perfect

Hello Austin, the image/video disappeared because the TV failed to power on completely. LED TVs are known to have backlight failures and I'm sure your TV has a defective backlight failure.

My understanding is that an LCD TV has a fluorescent tube for a backlight, an LED TV is LCD with an LED array for the backlight. Depending on what type TV, it's possible a technician could replace the fluorescent tube or whatever and get it working again. If it's a CRT TV, you might need a new PS or CRT.

Thank you so much the unplug the power from the system worked after hours of trying other stuff
Huge thank you

Blinking 5 times is a sign of at least one of the three video tubes overcurrenting, which will eventually shut off the image. It happened with me but with my red tube over-illuminating. The solution is to reduce the drive intensity on the offending tube. Remove the front speaker grill. Behind it you will find a panal with 6 pots, these are drive (brightness) and focus for each of the 3 colors. My fix was to turn down the red intensity to zero and (after a restart) bring it up slightly till the image was acceptable, colorwise. I did have to adjust all 3 intensities to get a decient color balance along with the focus's on all three tubes (the drive intensity adjustments will knock the focus out as you go). I used the auto-adjust patterns to focus on, and you may want to use a stationary image, such as a paused DVD scene or a video game, to focus on. I still haven't found a way to clear the error code, but I learned to ignore it. The result isn't perfect, but it's very acceptable and it'll do for awhile (and it didn't cost anything!). Good Luck.

If you get green vertical bars or green dots in the picture but not in the menu screen (Digital board symptom)

Okay, is the sound coming out and no image/video, if so, on your AV cable at the connection to your Xbox there should be a switch on one of the sides it switches between HD TV and TV if your TV does not support HD then switch it to TV and it should work perfectly hope this helps your situation :))

Hi,

If the sound is distorted, then you need to replace Sound board. If you do not have picture and sound, it has nothing to do with sound board.

There might be millions of reason and depends on the make and model of the TV.

On most of the samsung TV's, such problem might be due to defective Circuit Board. It can be replaced or repaired.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

good job

it is 100% sure that your tube is ok.

there are few problems in different section like 

• sound section for no sound
• video & crt base  due to low light in picture.
• red video output circuit.
• though problems are very easy & can be fixed at your house.but you need skilled technician.
