Screen getting darker

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

with the blue screen do you see any kind of error message or any blink code?

if so we can solve the error very easily

Shouldn't have bought a Sanyo. It's not the same company it once was. It's toast.

It sounds like your lamp is about to die out,this tv lamps are good for 6000-8000 life hours which is a average time of 2-4 years old and with time the picture starts to get darker and darker until one day black screen. Try Encompass .com ; shopjimmy.com

If you mean that the left side of the screen goes darker than the right side, then this is an indication of a faulty backlight. There are probably two CCFL tubes, one on each side of the screen. If one starts to fail, then that side of the screen will get less light and look darker. The tube may need to be replaced.

Hmm my dad's old t.v. just cut out on him it took awile to turn on this my be the end of ur tv so this might be a power problem but older t.v. loose there colour on the screen my uncle had a like 10-15 year old t.v the screen was like green when it was light but when u turned of the light or closed the blind's it's picture was ok so try that.

I have a two and a half month old Sharp, LC-19SK24U-W. It was fantastic with fantasic, clear, beautifully colored picture until two weeks ago. All of a sudden, the picture starting getting darker and darker. Nothing had been adjusted from day one when I set up contrast, etc. This comes and goes but most of the time is an issue. I can make it a bit lighter but then it is so fuzzy and grainy it is a very poor picture. Also, while this began, one time the television turned itself off and then back on without a power surger or anything.

HELP!

I am getting a black cloudy mark on the right side of the screen. It's not even on the part where a Wide screen picture would be, it starts at the wide screen area and gets darker going to the left towards the center. The TV is just over a year old. It's Wal-mart POS Ilo brand.
