This lights vary in pricing and I would go to the manufacturer's website and contact them, they will guide you to the nearest service centre or might even sell you one directly.

Hope this helps

First off there are many ccfl lamps in a typical LCD flat panel tv. Most manf wont sell them. They are almost beyone the average persons ability to replace and I doubt if they are evenyour problem. So to tell you to try to find them is ludicrous. If you were a very ecperienced tech you would not want to try and replace them. They are about the size of a pencil and very fragile. Get another tv!

I have a Polaroid 40gsr3000 40 in lcd tv. sound works no picture. think maybe inverter board. One board in middle of back .one long strip board that runs along bottom of tv. Is this inverter board?

What you have is an led tv . And the inverter for the back light led is there in the main board (mother board.) of the tv. Its no a separate board.
The the Log board you see is the TCON board which drives the led panel.
If you wish replace the inverter the you have to bay new mother board for you tv. In the model you have Almost every thing is integrated to the mother board like power supply ,back light inverter board the cpu section.
If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

Open up the TV and trace back from back lights to the circuit board!

It sounds that the back-light inverter has the fault. If there is any winding short [cannot detected by measuring with an Ohmmeter], this type of fault can occur. The only thing to do is replace the back-light inverter board. The LED blinks indicates a short circuit .

My tv screen went black

If you have problem with video only then the back light inverter board of your tv is faulty. You didn't mentioned any thing else. Is there is sound or not. If sound is ok then the back light inverter is faulty. There is no repair possible with the back light inverter board. You have to replace the bosrd with a new one. As you didn't mentioned the model number of your tv, it is not possible to sent you any deatiles like where you will get the inverter board and its cost. Try to add full discription of the complaint and the model number of the TV.

Anyway check the link bellow to see how the back light inverter board looks like.

I turn my tv on and i have sound but not 1 bit of picture i have try tons of things please help

The problem is no back lights.If the back lights is not working the back lights inverter is the cause of that, there's a blown surface mounted fuses or leak capacitor.So its better to check the back lights inverter board and find the blown surface mounted fuse cause of shorted transistor or transformer.Hope it will help you.Thanks..

Intermittently appearing vertical line -various colors - sometimes solid - sometimes stripe


These lines are possibly cause by a failing inverter cables from the graphics device transferring the signal to the LCD panel. Apparently, no easy fix for this unless you can reseat the inverter cables and if it won't work consider replacing them. But, the best thing to do about it is to contact your manufacturer and seek professional assistance to avoid tampering.

I have the same problem with my TV. Apparently it is a problem with the backlight inverter board. The only thing that has consistently worked for me is to switch the OPC setting to on (display). Get a small piece of electrical tape and when you turn the tv on wait for the OPC 'leaves' bar to load a bit and then cover the OPC light sensor at the front of the tv. (it is the one right beside the power light). Hope this works as well for you as it did for me. Good luck

Flat panel tv

I had a similar problem, except I had sound and 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!
