And I suppose replacement is the only option? The customer won't want to put
another $200 into this set, and in all fairness they shouldn't have to.

I have not worked on your model of set, but from past expeience I
found that a defective lamp can damage the ballast, and or the
starter. A defecive ballast can also cause a lamp failure.

In many systems the starter is part of the ballast supply.

You may end up having to change the two together to fis this problem.

Me again with this miserable Zenith DLP TV. I made a post about this
about
a month ago regarding lamp replacement, I was able to do it successfully
and
returned it to the customer. A few weeks later the customer brought it
back,
this time with a different symptom; the set tries to power but makes a
buzzing sound, and shuts off.
With the front cover removed, I soon saw the source of the buzzing
sound.
A small round white component off the HV transformer (looks something
like a
large diode) lights up bright blue appearing to arc internally. The lamp
does not power up at all. I checked the lamp and it is fine, so at this
point I'm suspecting a bad ballast...... but with replacements costing up
to
$200, I sure hope it isn't.
Thanks for any advice.
