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.

Based on service manual info, it cant blinks 7 times as per symptoms, please count again blinks. It can be 5 times.
If its 7 times blink, Horizontal Deflection stopped in this case. If you want to repair it at your own, please let me know to guide you further but it is necessary you should have knowledge of electronics.

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.
