Check your +B regulation, if it is going up (possibly leaky) so does the HV
and shutdown will occur.

Hi everyone

I have this TV  Model # 25TS56 C221 , Chassis #  25F800 7583

When turned on screen gets brighter and brighter with horizontal lines and
after about 8 seconds it shutts off. I measured H. V.  before shutting down
it was about 22K .I am suspecting leaky diode/transistor. Any idea which
part/parts might cause this.

Thanks
