I have a Visio LCD TV 2 years old not working -- i have a backlight but not screen

if it's a fast flicker, you could either have a backlight inverter problem or power supply problem. The problem with 32" sets Hannah is that they are not worth repairing these days as the prices have dropped like a rock. You can spend more fixing the set than buying a new one! The fact that its a 2007 would make me want to purchase new. Your TV is 7-8 years old and is at the end of its service life. Sadly, LCD TV sets were not designed to last as long as the old tube sets. 5-7 year life expectancy is typical. If I have been of service to you please sign my guestbook page @

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.

Tv have 2 long LCD inverter boards it probally require replacing.These 2 long LCD inverter boards job are to provided the tv LCD screen panel to have a backlight to the tv LCD screen panel to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy those refurbishes 2 long LCD inverter boards for the replacement.

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!

You will either have a fault with the inverter board which drives the backlights or a faulty backlight in the screen. If the problem is a backlight then a replacement screen is the only cure. One or the other is breaking down after it has been opn for a certain period of time, have an engineer call out & check with a tester if it is a screen problem.

The TV is a Plasma, it does not have a "BackLight" as it were, that is for LCD's only.

Vizio are fobbing you off. It will need either a Y-Sustain & Buffers or a Z-Sustain.

Could be some bad caps in the power supply but also the inverter panel.

may be a mainboard problem. If you can see the orange light it usualy means that there is power running through the TV... usually inverter boards are a problem when you do not see any backlight at all.
