Question about Samsung HLN467W 46" Rear Projection HDTV

Picture Issue - white discoloring artifacts

I've owned my DLP for a few years and just started noticing a line of white discoloration on the screen. It is very faint when you're watching TV but noticeable if a scene has a solid color in it. The discoloring is about 7in long and 2in wide - it almost looks like a shooting star. It is very noticeable when I turn off my set and the screen goes black before it shuts down. Is this a bulb issue? Any help would be appreciated.

Discolored Sides

Hi,Yes your problem sounds like the DMD board.This is how it works: Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens.Ths if your tv is a dlp if its a Lcd it will be an issue with your light engine: Here's how your tv works: Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

Sony 60" LCD projection TV has yellow screen discoloration

It sounds like you have a bad Blue Polarizer in the light path. I'm sorry but that is something you will have to contact a service center for. It's not something you'll be able to do yourself, I'm sorry, but that's the best advice I can give you.

Changing the lamp on a DLP LCD tv

Most definitely! The lamp is a consumer replaceable item and your owners manual should have instructions on how to complete this task. If you don't have your owners manual and more post your model number and i will get you some instructions on how to replace it!

Sony 60" LCD projection TV has yellow screen discoloration

I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
Good Luck.

Picture discoloration to left and right of screen.....

Hi! Guy,
This sounds like the G2 may not be properly adjusted, providing too much beam current.
This will some times cause feather edging, or lighter than normal raster on some scenes. This set should be serviced by a qualified service tech.

Side shadows on picture

it sounds as if there are speakers to close to the tv or the built in speakers are not magnetically sheilded properly (maufacturer defect) if u have or have ever had speakers on the left and right side of your tv then the magnets in them will discolor and distort the screen. sometimes even long after the speakers have been moved away from the tv it will still look that way. you may try going to the library( or online )and looking in tv repair books on how to build a homade degauser unless your tv has that feature built into it in the menu somewhere like some computer monitors do. I had placed the front speaker of a 5.1 surround sound system on top my tv and it cuased that same problem, but i found out that by placing a small round magnet with a hole in the center on top of the tv (after removing the speaker for good) right where the discoloration was.. had to flip it one side or the other to get proper immediatly took away most of the discoloration and over time it disappeared. I hope this helps. Please email me at as to your conclusion in case it will help others. thanks, Adam
