We have a Toshiba flat screen LCD that constantly blinks -- goes dark for a half second like the LEDs are turning on or off. Changing the picture mode can alter the rate of blinking but I cannot get it to stop altogether (although this has worked in the past). Any suggestions on how to fix this?
@alf222 let us know the exact model of your TV. If it is the screen that is blinking it is possible that you have a bad power board/LED driver or a bad LED array. Post some good images of all of your boards with your question so that we can see what you see. Use this guide Agregar imágenes a una pregunta existente for that.

I have a 2 1/2 year old Toshiba that blinks on and off. How do I reduce the numbers spoken about above.

I've got a 50 inch Toshiba telly in mind links as well he actually gets on your nerves after a bit and it's only 3 years old I don't know what to do about it either I'll try turning my back light down to 18 see if that works but if anybody else has got any suggestions what it might be won't mind knowing also just go out and buy a new telly and not a Toshiba one this time or all tell us the same thank you

I just fixed a 70 inch Vizio with this problem. It was a dead completely shorted diode on the power supply for the backlight driver. Since this problem can often be fixed by turning the brightness down it is almost certainly either the power supply or the LED strips inside the display panel. I would start with the power supply first though.

One of the chips is overheating. Use freeze spray to identify it, unsolder the heat sink, clean well, then use a good heat sink paste and resolder the heat sink back on. You can try turning the backlight down in picture settings as well. Menu-picture-Backlight. It is factory set at 100. Try turning it down to 50, then bump it up by 5 until the picture blinks. Bump it down 10 or 20 from there.

Amazing. Everywhere else said I needed a repair. I lowered mine from 100 to 80 and it stopped blinking. Its a little dimmer and I will probably still need to get the repair at some time but this will work well for now.

I've been having this issue about a month now. It comes and goes...so I'm a bit confused. Ant solutions? Or suggestions to self check before taking it to be repaired?
