Hear sound but no picture on my visio 1080p...help?

If it is a 1080p TV, then the TV always displays at 1080p. The source device and/or the TV will scale and frame convert the image to match the TV resolution and frame rate. When you power an HDMI device, it reads the TV's supported resolutions and audio formats over the HDMI cable, then it chooses whether or not to scale the image for the TV. The television then receives the signal and performs whatever image processing is needed to match the display needs. With many Source devices, you can use a setup menu to configure whether video should always be scaled up to 1080p. Some people prefer the image scaling of the television. However, if the Source does not upscale, it will limit the resolution of on-screen graphics, such as the program guide. So you'll probably prefer to scale your source devices to 1080p through their menus.

Take them to a TV repair centre as they are complex to repair. You may find that your homeowner insurance will pay for the repairs if you can demonstrate that it was a power surge that damage them.

I think a surrond sound system helps. I have the same problem, i can't hear dialogue either. I can't afford surround sound system so i have to keep turning volume up & down accordingly.

Our Visio 42" flat screen TV did the same thing. It didn't happen that often but sometimes it would go darker or the sound would go off until I changed the channel or turned TV Off then back On. I contacted Visio through my warranty and they sent me a flash drive to install info on my TV. Did not fix the problems. A year later before warranty ended I contacted Visio again. They sent a huge box for me to pack my TV in to send to the warehouse where they fix everything. It took about 2 wks. to get it back. Worked fine for about 4 months and the problems continued. I will not buy another Visio TV. I found out that they had many problems with several models.

See my reply to your previous question

AV inputs are for standard analog video which is 480i. HDMI and Component inputs are the high definition inputs that run at either 1080i or 1080p You won't ever get 1080i or p through AV inputs.

it sounds like you need to purchase a new video board from vizio which is expensive. upwards of 600 dollars. walmart has vizio 42 in and 47 in 1080p models around 500 dollars on sale this weekend. hope this helps let me know!

I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the BN_on (on) the backlight inverter and you still have no picture...you will need a new backlight inverter.


Hope this helps! Please rate!

Your going to need to measure the various power supply voltages to see if its a bad main or power supply board

If under warrenty then call vizio!
I believe its sound board but I could be wrong.
No easy fix, the part is 220$ service is 210 a used LIKE NEW 42-50 inch is 500$ shipped !
Sorry to say this but it happened to my 50 inch just before I heard a pop then it would not show a picture and had no sound.
Call them up if your tv is less then 1 yr old!
