Wd-52531 color is being overpowered by green and yellow


Hi, You are most likely seeing the effect of a defective optical engine. This is the part that processes and projects the picture onto the front screen. Physical anomolies can cause random blobs of colors and a distinct appearance of haze in the center of the pic. The only fix is to replace the engine, usually around $800 to $1000. THX

Yellow blob on your screen is caused by a defective optical block assembly. IF your set is under warranty, go to the nearest Sony service center and they will fix it for free.If its out of warranty it will costs more than a hundred box. optical block assembly is quite expensive part .

I have a Sony lcd data projector- VPL-SC50.. There is a big black blob in the middle, with other lines near the edges. And the blob is growing larger now. But it does not look like a burn out, it looks...


Normally a "blob" on an LCD is a delamination of one or more of the LCD panels. But, they are usually not black. You may have a poor ribbon cable connection from the main board to the LCD panels....there is a ribbon connection to each of the Red, Green and Blue panels. It's either that or a main board failure, but certainly soemthing you want the factory or other authorized service center to check out.

Good luck.

Left half of picture has a green ghost like shade


The sounds like the light engine is bad. Sony is notorious for blobs because of the three LCD chip inside consisting of a red, green, and blue chip. The light from the lamp is reflected and then combined back together to form a brilliant picture. Unfortunately one of the chips is bad, or has melted due to extreme heat from the lamps. This can cause the color blobs on the screen. A lot of people experience blue or green blobs in the center or on the sides of their sets.

Green Blob and Fading to White


Hi, i understand ur problem and try to the following steps. Shut down the NB and turn it on and repeatedly tap F10 key until you see a blue screen and then tap F9 key once and load the bios defaults. Wait for some time and check if u can see the lines and the green blobs. If u still see the same on the screen, it means that there is some problem with the mother board. If u have still warranty left on the laptop, contact the technical support of HP so that they will take the laptop for service. This will definitely work
Thanks and Regards

If you have the "red" blob in the center of the screen or you have "blue" blobs that show up in random areas of the picture then the only repair is to have a technician replace the optical light engine.
