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.
