ok when mine did that i shut it off then on then off then on again four times then unpluged it and plugged it back in and waited for a few minutes and it was fine if that don't work then its most likely an internal problem and it would have to be fixed by a professional

I've fixed several of these, easy fix, you will need to replace both 470uf 35 volt capacitors on the master and slave inverter boards. So you will have to replace a total of 4 capacitors. The capacitors themselves are about 50 cents a piece. The inverter boards are on the far left and far right of the set. You will have to remove the back cover to see them. If you don't have the ability to replace the capacitors, you can just order new inverter boards for $40-$60.

Hi,connect the tv to a stablizer..dont connect it direct from power source and make sure you place it in a place where enough air can reach it.

Any luck? We bought our tv (same one) in March of last year. It is doing the exact same thing. Time Warner has already came out and switched out the cable box and cables. We have a tv tech coming soon (contracted out from Samsung, of course...) Problem persists...

When I turn on My RCA L40fhd41 40" television, the LCD screen constantly blinks on and off like a strobe light. The power light stays on constantly, but the screen continues to blink

you either have a bad inverter board or bad floresant tube in the lcd panel Tops Electronis in Haverhil mass can fix you right up

I had the same problem with my 237V, I had to replace the power supply to fix the problem. I believe when it would work the output voltage of the power supply was around 19.2v. When the screen started to strobe the voltage had jumped up to 21.5V. A new power supply fixed it for me but now I think my main board is on the fritz.

I solved my problem when I tried using a different Power supply. The Batesias V171RTNRA uses a 12V 4.2Amp positive center post power supply. I discovered that I had a 12V 3.0Amp power supply that had belonged to a hard drive and decided to give it a try.

It worked like a charm. Something had gone bad with the original Power Supply causing strobing in the picture. With the replacement Power Supply it no longer strobes and works perfectly.

I am not sure if it's the lower Amps that solved the problem or not.
