RCA L26W11 Backlight Inverter Problem

I purchased my TV refurbished from in August 2007. Last year (November, I believe) I powered it on, but all I got was audio. I searched around online for a solution, but I didn't have the time to properly look. The problem continued, so I moved the TV to another room where it would be out of the way. About a month ago, on a whim, I tried powering it on, and it worked. I was fairly certain that it wouldn't take long for it to start acting up again, and it did yesterday. After looking around for more information, I tried the "flashlight test," and I could see very faint red images. Searching around on here, I believe that means the backlight inverter has gone out, correct? I finally pried open the back of the TV, but I couldn't find any scorch marks or bulging capacitors on the power supply or whatnot. My problem now is that I'm not too sure how to access the inverter (assuming that is indeed what's causing the issue). I don't know how many screws I've taken out, but I can't seem to get to it. I've never done this before, so I'd like more help from someone with knowledge of this specific TV. Any help is much appreciated! Let me know if any more information is needed.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

The solution to your problem is to not buy this junk from Wal_mart in the first place. You won't find any replacement P.S. anywhere. This is consumer fraud from RCA, file a consumer fraud suit against RCA. The law says the manufacture must supply parts for at least 5 years from date of sale. Dan@DBS

It definitely sounds like the video card / video board to me as well. The screen is most likely just fine, it could possibly be the power supply but I would not suspect it, you are correct in thinking the most likely issue is that video card. However make sure you order it from a place that will let you return it (if possible) so that if it doesn't correct the situation you aren't out the price of the board. If anything you could sell it on ebay, but that's not ideal as a backup plan if you know what I mean. If it doesn't fix it, it would almost have to be the power supply, as sometimes they can be just "failing" and not fully failed... having enough power to get everything on but the screen. However this is not the most likely case. Something to check into though before all this would be... If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.

Thanks so much, let me know! But I feel you are right on track with the video card. Check to make sure you can't just get refunded first though. I always buy my tvs with my American Express for just this reason, and have received full refunds on two different tv's, and one was $3000! So check that out first.
Thanks Tim

2007 visio tv will flickerimage on and off why wont the image stay on?

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 @

Most probably, Electrolytic condenser in the Power supply to display circuit may have punctured resulting in smoke coming out. Take tv to service centre. There is no other option.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
