I would assume that the 200v supply is running too high, causing the monitor to shut down. One problem I have run into in the past is that there may be a B+ adjustment on the PC board, (usually a very small trimmer pot) also glued into place and position by this nasty glue stuff. The idea of gluing it was to keep anyone from tampering with it, thus causing the B+ to run to high. Most times the only fix is to replace the pot, and adjusting it to the proper voltage.
