Picture is very blue, especially in dark scenes.


Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Faint red lines in a curved arch like pattern


For this problem, what you have to do is here I found this solution: Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labeled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. That should do the trick, Hope this is helpful. Please dont forget your rating.

Kines on Screen and Fading


Open up the front of the set by removing the speaker screen and the black piece of particle board. on the bottom right you will see 4 knobs. Turn those knobs slowly till the arcs go away. The 3 knobs on the bottom are for color. the 3 on top are for the focus.

sounds like bad CRT, some of these sonys have had defective CRT issues, usually all will come and go sooner or later (all 3 bad), you can pull the speaker grill off(either 2 1/4" screws on bottom or 6 1/4" on back sides) and pull off the Crt box cover (2'X3' piece) and lightly tap the CRT's with tv on, if they flare or get colored streaks in pix they are bad, CALL SONY 800 # and complain, also could adjust G2 (Screen control for color) for short patch. Will need new crts.

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck
