If you watch a DVD, does the picture also flash? If not, it might be just the TV signal. Are you using a cable/satellite receiver? If so, check it's connections. If anything viewed on the TV, using different inputs and a different cable/wire, is flashing, it is a problem with the light engine or color wheel, if the TV is DLP.

Element tv was working fine now get a pink screen only. Turned tv off for 2 minutes and tv worked fine then shut off and now power light flashes from bright to very dim. Tv won't come on now ????¿?


Sounds like power supply has fried, take to TV repairman or since its an Element just buy a new one that is not an Element. Get a LCD, LG is good.

I have a Samsung 55in curved TV. It has auto dimming. In the evening with the lights out it dims to where it is difficult to see the picture. Can I get rid of the auto dimming?


If the brightness on your TV changes automatically (randomly dims and brightens), you may need to adjust the:
  • Eco Sensor function.
  • - And / Or -
    • Energy Saving function.
    The Eco Sensor and Energy Saving functions adjust the brightness of the TV to reduce power consumption.
    • When you set the Energy Saving function to Auto, the TV changes its brightness automatically depending on what you are watching on the TV.
    • When you set the Eco Sensor to On, the TV changes its brightness automatically depending on the brightness of the room.

The light in my 47lb45h 47


Sounds like you have a power supply that is starting to fail, or your backlights are starting to fail. Hopefully it is just your power supply, as this can be fixed.

I type slow, I have a Vizio M261VP LCD TV, I purchased it not working. I purchased a new power supply. A light comes on and flashes in lower right hand corner. I t does not flash on and off it flashes...


Good day sir chris!!!!

Welcome in fixya and I'm happy to work with you...

OK lets proceed to your TV problem..

The possible problem is not the power supply...There some shorted parts on inverter board,T-con board or main board so that the power will not initialize due to that shorted problem..

I teach you how to find which board is shorted or cause of that fault..

Just follow this procedure below.
  1. Open the back cover
  2. Look at the inverter board..it is slim board that have small transformer on it.
  3. unplug the inverter board first.Then try to power it on...
  4. If the LED on front of TV will not flashes from bright to dim it means you have shorted inverter board try to replace it..
  5. If the flashes remain..go to next step..Power off tv then reconnect inverter board,after that unplug T-con board..Then power on.
  6. If the LED on front of TV will not flashes from bright to dim it means you have shorted T-con board try to replace it..
  7. If all those procedure done but still problem persisted the only problem is main board..Replacing main board will fix the problem..
NOTE: When unplugging and replacing of all board make it sure to memorize all connection or its better if you take a picture on it for future reference..

Hope this solution will be helpful..Any rate will much appreciated..

Thanks for using fixya..have a nice day!!

Ln55c650 keeps flashing bright to dim very fast after about 30 minutes of being on if i shut it off for a few minutes it goes away til about 30 minutes the picture never goes away just gets bright and dim...


I had the same issue occur on my ln55c650 (screen flickering, not the actual image but the front lights flashed which was too distracting) and they had to replace the power supply pc-board. Seems some issue with power module in the TV rather than the side panels. Luckily for me, TV was still in warranty.
