The screen turns blue after about 2 minutes of turning on the TV


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.

Tv comes on for 10 seconds then fades to a green tint then turns completely green for a few seconds than turns off


Hi,
Symptom shows tv got problem with green picture tube that need to be replaced.
Rear projection tv has 3 picture tubes, red-green-blue to make color picture.
Since its an old model so spare parts would hardly be available and local tv repair shop will help you to arrange required part, if they can.
Thanks.

These sets have weak picture tubes, this may buy you some time. It is not worth changing the tubes in the set. The cost would be more then its worth. Try these adjustments until it completely dies. I have the same set.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Blue Screen and TV shuts off


Yes, you are correct on the phrasing. The CRT's were a common issue with these units and all three must be replaced as sooner or later the green will follow the other two CRT's. It was a great model and had a beautiful picture when operating normally. The CRT's are costing about 200 each for rebuild as the green and blue are mostly no longer available. Your repair cost are going to approach $1000.00 or more.
