This VCR was in for service a few weeks ago, SMPS was dead, replaced the
following:
Q1 - C4418
Q2 - ECG382
D02 - IN4148
C09 - 22uf/16v
Then the display was blinking when powered up, found ZD6 leaky, replaced
it with 33V/1W zener (I think this is supposed to be a 43V zener?),
anyway, ZD6 blows within a minute of VCR being powered up. What could be
causing this? What circuit(s) does this supply?
Thanks in advance,
