    Well tried that already and the whacking test use to work before but now its just like white spots which appear at the same spots every time i turn my HDTV on its like white and pinkish and yellowish. I figure out that the three parts at the top are sort of messed up i think. It sort off feels warmer than the bottom three slots. and Yeah i opened the HDTV. and a Transformer gets really warm in a small amount of time. Any ideas

HI,

It's probably the flyback transformer and associated diodes in the same circuit. It's an easy repair if you know how to solder.


TRY THESE,


ONE: Do the hard reset. Unplug the power cord for 4 hours then power it back up. That will restore all internal soft codes into the set.

TWO: Give it the whacking test. Just bang on it with your fist; strike it at the top, back, sides, etc, to see if you can restore the picture. It is possible that some loose wire, loose connection or cold solder joint has begun to act up and the banging will sometimes get it back in order. Worth at try.

you have to contact the service center if the above steps workout......

Let me know if you need more ideas.
Thanx for using fixya.

Spot in center of screen, if the color pictureis black the spot is blue, if the picture is white the spot is yellow.


Spots in screen is commonly caused by defective LCD on the optical assembly. LCD replacement is very difficult. I suggest to contact the nearest service center at your area.

Philips 60PP9200D went black and white.


Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo 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, pixelation ,black and white picture,even vertical lines.You will need to replace the light engine. Have a blessed one!

Picture is red


If you are running component video, make sure the blue is plugged in and in the right spot. Component video works like this: the green is a black and white image, the red and blue are cover overlays to make the image display properly. So if everything looks plugged in right, then try plugging in a composite video (Yellow) or S-video cable switching to the appropriate input, and see if the image is still red. If so, go to the set up and set the set to factory defaults, and see if that fixes the color issue, It's possible that the color settings on the TV are messed up, with the S-video plugged in go through the set up menu and see if you can correct the color issue IF THE IMAGE IS STILL RED WITH THE S-VIDEO OR COMPOSITE VIDEO, otherwise the issue is a problem with the component video cable.

Large yellow spot in center of tv screen


Sorry, but there is no cheap method of repair for this unless it is in warranty.

This TV will require replacement of the LCD Prism unit.

This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.

Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.

This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty.

Good luck.....

I have a sony kf-42sx3oou, i have just had the lamp replaced, since replacing it a few blue spots appeared in the top right corner but today a yellow line has appeared on bottom left hand corner, could you...


This problem was probably there before, but you only noticed with the new "Brighter" bulb.

This TV will require replacement of the LCD Prism unit.

This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.

Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.

This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty. If out of warranty, I suggest living with it or selling it if out of warranty. Turn down the Brightness and it will not be as noticeable. I am sure you only see this with bright images.....like white backgrounds and such

Good luck.....

HX-P4241W appears yellow. Left and Right of screen are yellow


Yellow is the lack of blue. It can happen when you are running your contrast - which is your overall light level - too high.

Try turning down your contrast. On CRT tech, contrast should always be run at half what the factory allows as full, on the user controls. Full up is what calibrators call Torch Mode, and is NOT the way to get performance to be in the linear operating range of CRT tech.

If your sides are more yellow than your middle, your set may need lenstriping. Mild yellow on the sides is not uncommon, and usually not noticed. But heavy yellow on the sides would indicate that the blue image needs work on white field uniformity.

Yellow is the lack of blue, in CRT tech.

3 green spots on the top center of my projection hd tv


I had a similar problem and brought it in to a technician for a quote of $860 to fix. The problem - speck of dust on the optics. If it weren't under warranty I would take it apart and blow off the dust myself.
