Question about Televison & Video

1 Answer

I pulled my WEGA kf42we610 apart to replace optical engine, and clean out 4 years of abused dust bunnies. needless to say I disconnected some of the cabling and I'm now having issues putting it all back together. does someone have a simple diagram that shows how everything cables back together. something like "connect B cable on C2 card to Front or side conector on optical block. Many thanks.

How do I change the optical block in a sony tv


Disconnecting wiring from power supply block

This step may be optional, if power supply block must be transferred to purchased replacement optical block. Undo the blue plastic-coated wire holders to release the two wire bundles. Disconnect the connectors shown with the dotted lines in the photo below. One, which presumably provides power, is disconnected directly from the power supply block, and the other is a regular wire connector.a837b7e.jpg

Disconnect the optical block fan wire connector:

Disconnecting the wiring from the optical block circuit board (C Board)

Carefully pull up on the three wire connectors directly connected to the top of the C Board:

Final wire disconnection from C Board

Remove the screw and gently pull the blue ribbon ribbon cable out of the side of the C Board:

Your optical block should now be entirely free of the TV and ready to ship. I recommend adding specific protection for the projection lens, then sealing the whole unit in a bag to prevent infiltration of dust or packing materials, then carefully packaging it with substantial padding.

Removing the projection lamp (in cases where you are installing a purchased replacement optical block)

Loosen the hex screw next to the projection lamp housing, and pull the lamp and housing outward from the metal clips.

Sony Grand WEGA KF42WE610 42" turns on and off


If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

Please make sure that the videos sources are connected properly to the TV.

Try Power Resetting the TV.

Please disconnect the power cord from the wall outlet (for approximately 1 minute), then reconnect the power cord and check whether the issue is resolved.

Also try connecting the TV to a different wall outlet and check if that helps.

Cleaning Optical Block


Sorry to be teh bearer of bad news, but the optical block (light engine) can not be dis-asembled outside of a cleanroom. You can remove the rear cover of the set and clean the mirrors and glass. That may help, but usually these typesd of symptoms are an indication that the light engine is starting to fail. The light engine can be replaced by you if you feel comfortable. The part is still available.

Keep us posted.
