I have a sony kds 55A2000 and my lamp went out so i replaced it. and it startes up fan goes on and off . and tv shuts down light still blinks red? My optical block is getting a light green yellow tint but...


Lamp Fan should not cut off and on it should run at all times when TV is Turned on.Lamp Fan is designed to run when set is turned on to Keep Lamp Cool otherwise Lamp will burn up.
Yes Bad optical unit block could also cause set to shut down.But most of them will Play but with Dots,Green yellow tinit or Big blue Spots

Red Lines through picture when screen is dark, back ground has a red tint. On my 48 "Sony Rear Projection" TV


You can try adjusting the Red color output. (Very touchy adjustment)

If you take off the front cover/speaker cover, there should be a access panel. Behind that, there should be a small square black box with 6 screws on it. This is the focus block. (At least this is where most of them are located)

It sounds more like you may need less red in the mix. There is a screw for each color. R, G, and B. Do not mess with the focus screws, just the ones labeled 'SCREEN.'

Go to an unused input where the screen should be dark. Barely turn the red down in a dark room so that the red spot is at the same level as the Blue and Green.

Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it.
Very HIGH VOLTAGE. I found that out the hard way.

Do not turn any of these up too high or damage may occur and the TV may detect a short and shut off.

I have found that if the three colors are adjusted in a dark room to where the 3 color spots (R/G/B) are just barely visible on the screen at equal levels, there is a pretty good color balance.

I hope this helps! Just be careful.

Blue hue accross bottom of screen - Sony KF-50WE610


You can try doing this, turn on the Tv and select the service menu, if that tint also shows on the menu, it's most probable to be your DMD board, but if it doesn't it might be the video board..

Green tint/hue to entire screen


The first thing I check for this problem when doing a service call is the screen control. It sounds like it needs to be turned down a bit. The screen controls are in the front of the set. Pull off the front speaker grill, you have to pull it off there are no screws and it's a little tough to pull. Remove the panel behind the speaker grill. The screen control is normally black with 6 controls. 3 controls labeled Focus and 3 controls labeled Screens. The center controls are for the green. Find the controls that are labeled Green and turn it counter clockwise until the black is not green anymore. If there is glue on the control, then, peel it off. You may have to adjust it a bit to get the right alignment. When the set is turned on, only use one hand inside the set.
