In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks!@#

remove back cover then check the CRT tube if there is color red cathode how?by using a wire or test prove connected in ground in your TV very quick if red screen flashes your CRT is good then check your CRT board socket find the driver transistor of red cathode then check it if shorted replace thank you

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

You need to verify first that you do have 24vdc feeding the inverter boards, if you do have 24vdc then we can be sure it is the inverter boards. The inverter board will have very small surface mounted fuses, check for that also.

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!
