I have never heard of two CRts being shorted at the same time. I would suggest calling another shop as They are most likely trying to take advantage of you. Go to the following link and leave an email indicating your model number and one of their techs will email you back and ask you to explain your symptoms.
heres the link.

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.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

My picture is green the it shuts off with light blinking in front


that's very hard to fix, you need to monitor every test voltage pin if is in normal. try also replace crystal capacitor thats one monitor with the jungle IC.

Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off
