A friend has asked me to look at the above set, symptom is that pressing
the power button causes a few relay clicks and then nothing but the red

I have got a somewhat strange problem with a philips dvd962sa dvd/sacd
player. When I put in a disk it will read it for about 2 minutes and

transistor in the dc - dc converter but an exact replacement is not easily

I am attempting to track down an intermittent arc (I think, but not
sure).  My test equipment instrument has a crt circuit with an 11KV
