RCA R52WH74 (ITC222A Chassis)
Hi:
Thank you for your last response to my question concerning the FL231 fuse that keeps blowing.
Two questions I have for you:
1) Is the "Convergence Power Supply Board" the same board that the FL231 fuse and the flyback transformer is located on?
2) My chassis is actually an ITC222A chassis, and the board I *think* you are referring to with the FL231 fuse is actually shaped differently and looks a bit different that the link you provide me at http://servicemanuals.vstore.ca/. So, I'm wondering if there is a different place I can obtain replacement boards for the ITC222A chassis.
Also - do you know of a way to get ahold of the service manuals and/or schematics for these boards?
Thanks for any help - you've been really helpful so far.

The problem is related to the Convergence power supply board, which is shorting out and blowing fuse FL231. You will need a new Convergence power supply board to repair the Issue with the ITC222 chassis. You can get a replacement board at the following link.

No the board that has the FL231 on is the ITC222 deflection board. The other board is above the chassis in a seperate frame that runs across the set the convergence power supply is the board on the left above the board where the fL231 is. Yes the ITC222 and ITC222A are the same chassis. As for the service manual that site should have the service manual under the thomson category as the ITC 222 chassis is actually a thomson chassis made for RCA.
I found a service manual for my RCA HD52W67 at http://www.servicemanuals.net
