General, these failures are produced by power sources, because of which refer to a wider area, so that can
be divided them two conditions to explain: no B1 130 V and existing B1 130V.
(1) No B1 (130 V) voltage (voltage of network 220 V ac)
These failures may be caused by power supply switch.

(2) Existing B1 130 V
These failures may be caused by abnormal operation of horizontal scan, to confirm which can
observe the filament of tube whether bright on. If determined horizontal scan in abnormal operation, look
for the failure start from the horizontal drive stage. Search upward to TMPA8859 with method of
checking DC voltage and waveform according to sequence: PIN13/H.OUT port→ PIN17 power supply→
V707/9V output.
