Bob, I've done many of these. Only one with a CRT problem had a line down the middle. I assume it was internally cracked. I replaced that and the fired up, green got real bright and shut down. I replaced the CRT driver for the green. Then, the picture was severely bowed and stretched. Found DL032 leaky(70 ohms), about the center of the board. I have this on order, so hopefully this will fix the set. I tried for three days to get the convergence before I was convinced there was another problem on the deflection board. Just finished another one with a split cap CP010, 220/400v. I didn't see the cap until I was ready to put it together. Set came in dead but would try to come up three times. Per Lynn Davis with RCA, he suggests try heating or using a torch on the solder pads of the small signal board for the ribbon and other connectors. I tried that and this set came on(even with that cap split.) ESR on the cap was pretty high...about 20 ohms, so it wasn't totally opened. You're right, not enough money on these.... BTW, doesn't RCA pay extra per CRT replaced? I haven't entered the claim yet, but I think some manufacturers do.

This is the second one of these I have had recently with severely leaking CRTs (this one has both leaking blue and red). I have also seen many other techs on the various email forums indicating the same thing which is one of the reasons I guess the CRTs are on factory backorder since February. The cabinet design of these sets and acesssibility make them a real sonofagun to replace. Just the electrical convergence/geometry alignments for one CRT are level 1 (9 ponits of alignment), level 2 (25 ponits of alignment), and level 3 (195 points of alignment). This is for EACH color in EACH mode (480p and 1080i). I feel bad for us servicer's who only get under $200 warranty labor for this. The other issue is that I believe these new CRTs are the same as what was originally installed in the set so I wonder how long before they also start to leak? Have any of you had the leaking CRTs on these ATC221 / ITC222 chassis yet? I am curious to see how prevalent this problem is!
