Sounds as though the system may have overheated. Do you regularly check the filters and clean them? An airduster can also help to blow dust out of hard to reach places.

I have a problem with the picture on my Infocus IN1501. It has small squares on it and I see every pixel. How do I remove this?

Generally the screen is full of pixels, and thats a good thing.
It's a problem when you see the pixels that should be off, and don't see them when they should be visible.

So I presume that your pixel problem may be the first type where they appear when they should be hidden.

Now it would be good to know if the bad pixels are all one colour, or if you have chromatic pixelation problems.

Monochrome pixel problems are better than chromatic pixel problems. But alas all pixel problems come back to the DMD or the colour wheel.

Either way your machine is basically compost material for the garbage shredder, unless you want to pay big money to replace the faulty bits.

Ask the local serviceman or servicewoman to give you a quote to look inside the unit and see where the pixels have gone astray.

I turn tv light comes on but i get no picture or audio....then light indicator blinks red

Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,

Make sure that the resolution shown by the projector matches with that of the computer resolution. Many projectors does it automatically.
But if there exists a problem in resolution matching, there is a chance of getting partial picture. So better check that the resolution shown by the projector matches with that of the computer.

Also, the pixel may be degraded due to,
  • Their susceptibility to heat; the organic compounds used in LCD filters - in particular the blue - can be broken down by excess heat, resulting in a degradation of image quality.

  • "Dead Pixels"; pixels can become permanently on or permanently off, and while this is barely noticeable with one dead pixel, the presence of multiple dead pixels can be a irritation.
The only way to fix the problem is to replace the 3 LCD panels which, if you could get the part would cost you more than a new one.
LCDs are really difficult to make so lots of them do actually get passed with dead pixels on them.

But i suggest you to get some advice from the service center too.....
Hope my info solves your problem.
Thanx for using fixya.

42" cracked screen

If you have household insurance for damaged goods, this would be a good time to make a claim.

If there is no damage to the plastics around the TV, then who knows, it may have been cracked in the box *wink* *wink* after all, accidents happen in the factory too. ;0) I never said that though.
