Question about Sony Grand WEGA KF-42SX300 42" LCD TV

1 Answer

Yellow spot in lower right hand corner

Sony Grand Wega 42inch. LCD TV.

We recently acquired a yellow spot approximately 6in. long and 4in. wide in the lower right hand corner of our tv. It is always there.
In addition the color goes to Pink and Green intermittently. Sometimes it is fine and at other times it goes to all faded pink and green.

When we watch the channels in HDTV the color is fine.

We replaced the projection lamp about a year ago because we had no picture at all.

    It is model number KF-42WE610. Yes the yellow spot is there when the menu is displayed and on all unputs.

    Our Sony projection LCD Grand Wega TV has about four yellow bands that run from the top to the bottom. Any ideas what this may be and how to fix it?

    Is the model number supplied correct for your TV? Do you see the spot on all inputs? Can you see it with the OSD and menu displayed?

You have pretty much narrowed it down to being a bad optical block. This isn;t good news, since the optical block is probably the most expensive part in the set. Your best bet is to contact Sony customer support to see if the will allow some kind of accommodation for the repairs. Sorry for the bad new; hope it doesn't effect the rating you give me for the solution. Thanks!

You have a Optical Block that is bad. I would call Sony at 1800-222-SONY and see if the would assist you in the cost of the repairs.
Hope this helps,

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.....

Bright blue spots on lower right corner of Sony Grand WEGA KF50WE610 50 in. Rear projection tv


The spots are from dust in the optical assy. It would need to be replaced because the only way to fix the part would be to disasemble it in a dust free room.
