With our help and some skill at soldering,can be done ....

Don't worry about CRT ( Cathode Ray Tube)

Blue arching is convergence issue = needs STK392-110 IC's
replaced = requires chassis pull.........T.

How do I know I need a new projection lamp? My tv


This set does not have a lamp. It has 3 crt tubes that converge to create a color picture. The convergance is off a little causeing this affect. Go into the menu and look for convergence or magic focus. You can download the owners manual from Toshiba website to do this. You will need the remote that came with the set.

sounds like it is most likely the convergence power supply board, if it were just one color It would most likely be the convergence board itself

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck
