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.
