Mottled background

Check the cable going into the back of your monitor and the cable from your monitor into your computer, one of them is most likely loose.

This seems to be an inherent problem with this make of TV. It a weakness in the Liquid Crystal.
Sorry couldnt be of more help..

This is normal behavior when shooting in low light. Just like when someone is speaking softly into the phone, you may turn up the volume on your end. Any background noise, you can now hear more.

Similarly, when there is low light, the camera turns up the amplification on each pixel. Some pixels naturally have a bit more background noise than others, and these show up as bright spots. A higher ISO setting where the camera is more responsive to light is where this occurs.

At a high ISO, taking a picture of pure black shows up as a mottled grey with a few bright spots for pixels that have a lot of noise.

You can overcome this if you have a tripod - set the camera to manual and a use a lower ISO setting. Rotat the selection wheel to M for manual and then press the ISO (just above the function set) button to scroll through different ISO settings.

Photoshop and other programs have noise reduction tools and a tools to remove "hot" spots as well.

You either have a malfunctioning LCD controller(T-con) or the panel itself is faulty. The T-con is very inesxpensive and easy to replace but the panel is gonna cost you nearly as much as a new tv. Let me know if you want to give the t-con a shot so that I can guide you to fix it.

u need a new inverter

It's possible it could be the transfer cleaning unit, but it's more likely to be the fuser or the transfer belt itself. If the hot roller is old or dirty or the press roller isn't providing enough tension, all of the toner might not be getting fused to the paper.

If only one color were showing mottling, it would probably be the developer, but it's unlikely that all four developers went bad at the same time.

that is a factory defect you call the dealer for the warranty.the defective part of your tv is the inverter board.this board supplies high voltage supply to the backlight cold cathode flourescent lamp.This lamp is the one illuminating the screen of the tv..the lamp is installed at the top and bottom of the screen thats why the center of the tv is dark because the lamp does not lit well..tnx

hope i help you
please rate my help..

your blue crt is DEAD crts are not avail any longer sorry

This may be caused by the electrical outlet, try to run it off a extention cord from another room and see if the lines are still there. If they are you have a loose ground in your outlet. If the line still show them check your cables that feed the a/v signal to the tv. I have had this happen and it was just the outlet, hope this helps

Faulty (or wrongly) remanufactured cartridges can produce a 'background' to a print, which can be even across the page or have a mottled effect.

Do a printer self test page (press the arrow button).

put the old toner cartridge back in and do the same.

Does the background show with the old cartridge ?

If it does, its a drum unit problem, if not its a toner cartridge problem, and that should be under warranty if you've just replaced it.
