You have a bad flyback transformer. This is a common problem that eventually goes bad in the ITC 222 chassis. You have to get the model number with the code at the end of it after the /. And sometimes you must have the numbers from off the flyback itself. Try to contact MCM electronics for the flyback at 1-800-543-4330. First see if they can match it with the model number with the code after the /.
Hello Chris this problem is coming from your high voltage circuit which consist of the flyback transformer and the horizontal output circuit, the most common problem when it is acting this way would be bad soldering on the flyback transformer or defective transformer but keep in mind it can also be caused by the horizontal circuit or a faulty lamp as well can cause this problem, what i would recommend is to have a tech come out to service your tv set this should not be an expensive repair since most of the time it is just bad soldering on the flyback thank you hope this helps.
First and foremost, disconnect the power cord from the mains.
Next, after having removed the back cover from the set, discharge the tubes' residual high-voltage to ground using a suitable tool.
Access to the transformer is pretty much staightforward here.
A few hardware removals and you can then get to the board and transformer..
Mark, then remove all leads that go to the unit.
INstallation is the reverse of removal.
Be sure to replace the driver device, just to be certain...accordianman
This transformer does not come with the hv lead,if the arch is coming from the side of the transformer,cut the side of the plug were it goes into the transformer and the lead will come out,there is no voltage stored on the hv lead after the set is unpluged for a few min.,the transformer you can get at any rca repair center.
