When switched on: sound and picture appears. E/W amplitude is too
small, Focus is not correct, HOT T504 (2SC5331) runs very hot, R536
(6.8R 1W) runs very hot. The TVset switches to SBY (protection mode)
after aprox 6 seconds.
When reapplying power the same event happens.
Running the set on a ballast lamp with HOT disconnected shows no
problems, B+ however is believed to be a little low (130 VDC rather
than 148 VDC)
Could the HV transformer be defective ? other suspects ?
TIA
