My Audiovox under the cabinet LCD TV has audio, but no video. The unit is less than 2 years old and we only use it approx 2 hours a day. We don't swing the screen up flat too often ...maybe twice a week. The screen is black, but it did not fade out. Could it be the bulb? Audiovox wants $135 to fix it. I'm debating on whether I should attempt to fix it myself.
Ok, here is a bizarro solution that just worked for me. It is a solution to the problem, not a technical fix.
1 Turn unit on
2 Using remote control unit press "DVD" button, upper left.
(When I did this the Audiovox screen appeared)
3 Then using remote control unit press "TV" button, upper left next to DVD button.
(For my unit, this gave me a TV picture)
I don't know how to rate solution #2 but IT WORKED! Thanks so very much! I was ready to go out and buy another unit! You saved me! It was very bizarre because I didn't accidentally hit a button on the remote.....I walked out of the room and back and the screen was black.
Thank you for your response Paul. You have given me enough information to make an educated decision. I guess I'll be handing over another $135 to Audiovox to fix it. I hate to do it, since we already paid over $500 for it 2 years ago. Unfortunately, we are having withdrawals and need our kitchen TV. A new one means more money and ,possibly, more headaches.
Happy New Year!
Hi amanda - i just had a customer bring in an audiovox ve920 with the same problem. i took it apart and there's a capacitor and possibly a transformer on the circuit board behind the screen that are burned/melted. i contacted audiovox to see if i could get a schematic diagram to attempt to fix it (the capacitor is burned beyond recognition), but they refused and suggested i ship it in for the same $135 charge. i'm going to investigate further to see if i can figure out what kind of capacitor it is and see if i can get one from someplace like shadio rack.
as for your question ("could it be the bulb?") i want to let you know that lcd panels have a tube across the bottom that's called a cold-cathode fluorescent light (ccfl), and they do go bad. the ccfl provides backlight to the screen, which means if that were the problem you'd still be able to see something on the screen, it would just be very dim.
i don't have my camera with me, but i will bring it tomorrow and possibly upload an image of the bad part.
if you decide to take the screen apart, let me know what you find out.

The VE1020 didn't come with a mount. It came with round plastic spacers (16) that were 1/4", 1/2", and 3/4" thick. You could stack these on the mounting screws to get the clearance you needed for under the cabinet mounting. You will note that there are 4 through holes for the mounting screws, one in each corner of the chassis. Sheet rock screws of different lengths will work. You can easily just cut four small blocks of wood or use 3/4" - 1" wood dowel cut to the length you need. Drill a through hole in the dowel. Paint them to match if they will be exposed.
Turn the unit off, push the setup button 3 times. Press the seek left/right to switch between cable / antenna tuner modes. When cable is selected, press the channel up/down to switch between cable modes. When the unit turns back on, it will rescan for channels.
The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. I can't say it's 100% the problem because I can't actually look at the tv over the internet. If by chance the TV is still under warranty with some type of extended purchase plan, go that route. If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.
I was able to find a junk unit (screen no good) on eBay -- swaped out the dvd player - everything has worked fine since (except 6 months later I had to swap out the audio card from the same junk unit - and now all OK ever since.)
I had the same problem, except with a flashlight I could see AUDIOVOX when i turned it on and I could see the video when I put a DVD in. It is hard to see even with a flashlight so you have to look closely. Well, I researched and investigated what might be the problem because I was upset that I had the TV for less than two years. Everyone was saying the inverter was defective. Apparently the inverter is what gives the LCD screen the back light to see the video. So I called audiovox and found that thier part's selection was only a power board and a remote control for this TV. I asked them if they could get me an inverter and they did. With shipping cost it was approximately $150.00. They ensured that I know that there is no refund on this part (which is common for electical parts). So I took a chance on it not being the right part for the problem. I replaced the defective inverter myself and it worked. It solved my problem. The inverter is a circuit board that plugs in and has a few screws to hold it in place. I had to remove the back cover first and a couple of brackets inside the tv to get to the inverter and replace it. There is a quite a few screws so I recommend writing down where each came from for easier reassembly. I hope this helps!
