Hi Meat Plow,

Boy, I forgot to say in all the details, that the 27KV is within specs.

To answer your question, yes, 27KV is within specs.

However, if you have read and remembered what I said, you would realize
that excessive HV is not the cause of this problem. "WIth the screen turned
all the way down, the TV stays on". Maybe not my exact words, but it should
be close.

Hi,

I have a "Super Dog" Curtis Mathes/Samsung TV model CM27001S
(mfg. 11/01) in my shop. I have SM (.PDF file).

I have updated this from my original post and added more information.

The TV will turn on. There is around 27KV (measured) for the CRT. There
is vertical deflection and good sound, but just as the picture begins to show,
the TV turns off. Note: This happens every time you turn on the TV.

Is the 2nd anode volts supposed to be 27kv?

Have you found where the shutdown is coming from ?

Some circuit fault is causing the shutdown...

Have you checked to see if the micro is being reset ?

I don't have a diagram, but have you tried adding a little more damping
capacitance across the HOT C-E junction and see if that makes a
difference.

R!
