If you put a scope on the base of the HOT, do you get the startup pulse
train? If so, this means that the kick start for the scans and power supply
should normally be okay.

There is a chance that there is a scan or HV fault, and it is going in to
the protect mode. In many sets, when they do this type of fault, I have
found them to have defective capacitors, and or a defective flyback
transformer. It is also possible at the same time to have some other failed
components as well.

My old (20 years) faithful Philips TV-set died last day, and I have tried to
find the cause, without success. As far as I know, I think it is in the
startup circuits.

What do I know?

-Chassis: 26CS5779/13Z
-Death: Just died while watching
-Fuses: checked OK

Symptoms:

-No high tension.
-Faint hiss in speaker
-Responds to remote control but channel indicator dead.
-13V and 190V test points on board have no voltage.
-140V collector-emitter voltage on flyback transistor. No base voltage.
Unsoldered and checked OK.
-Most transistors tested by using diode test. 0.7v drop. =ok
-Diodes checked OK.

Any clues as where to look?
thanks a bunch!
