Question about Televison & Video
the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck

Look at it on the QVC channel where you have boxes with straight lines. If any of the 3 colors are bowed and 1 inch off, then it needs parts inside. If the colors are straight and only 1/4 inch off, you can adjust it. Using the remote, in the menus find convergence to adjust. Your user manual will explain it. At WWW.Toshiba.com you can download the manual if you do not have it.

I don't recommend working on the TV unless you have some experience and knowledge relating to the safety issues and electronic repair. Most rookies will not successfully complete the repair and probably do more harm than good.
Sometimes when the convergence chips fail, the TV senses the changed load condition and shuts down.
Unplugging the blue, red or green convergence connector on the convergence board removes the overload condition if the IC is shorted and allows the tv to run, with one color missing.
This is done with the tv unplugged. Then plugged in and turned on to see if it starts. Turn off immediately if you here it start.
Now you know if convergence failure caused the shutdown. You can repair the convergence circuit if that is the problem.
If this has no affect, then you could have a number of different faults in Vertical output, Power Supply or HV circuits that require the expertise of a qualified service person. This would be a bench repair in most shops.
If you live around Calgary, Alberta try me instead:
Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.
Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.
