this problem is usually related to the power to the blue gun. (this is a little complicated, even for a TV tech). it provides the blue overlay for the image.

you can also try to unplugg the cable for at least 4 hours, then it will (usually) reset all the voltages.

the last thing you can do is call a repair technitian to check the solder joints if they are "cold soldered", the circuit boards are defective or if there is a short. This should only be attempted if you are EXPERIENCED in electronics. the average cost to have a tech come and fix it is $400+ AND even then he/she will recommend sending the TV to a repair center, which then adds transportation cost. That may not be an option, considering there are new TVs out that cost double of the repair.

These are the logical solutions to your problem. If these do not appeal to you, Sony can also help you at 1-800-222-7669 or 1-888-772-7669 or

Hope this helps

Cost of repairs

I would say that a fair price to pay for the repair should be about 1/3 of the price of the TV.

Convergence ICs are bad need to be replaced. You will need to replace both of them also check the resistors right next to the IC often 1 or 2 of them burn out when the IC goes.
