Older SONY Bravia tech question

[BushyWill]

I have an older SONY Bravia TV. Recently tried to assist my daughter setting up the TV as a larger monitor for her job. Found a solution elsewhere. However, when I fired it up after she left, there is a vertical band of colored stripes in the middle of the screen. I've tried resetting the TV. nothing seems to work. Any ideas regarding a fix? I've attached two pics which better describe the issue.

Thanks for any advice.

I'm no expert but once had a television with something very similar and according to the engineer it was beyond economical repair.

Thanks LCDseeker. I kind of figured that but one never knows.
