My out-of-warranty Samsung DLP(HLR4667WAX/XAA) has been plagued with issues for the last 6 weeks. Each time I repair, something new happens a few weeks later.
First week of July, it was the lamp. Two weeks later, the color wheel. Now, after two weeks of use, the set won't turn on at all. For what it helps, the TV seems to make all the startup noises that I would expect - Just no picture.
Last week, the TV exhibited similar symptoms if I turned it on while the Xbox is on. If I turned the TV on before the Xbox, It would turn on most of the time. Now it wont turn on at all.
My research tells me it could be the ballast or the power supply. I'm not sure which direction to follow. I've read a lot of accounts of people who replaced their ballast and still met failure. Has anyone been through this, and if so, how did you finally resolve it? I'm thiiiiis close to buying a new TV because of all of the issues I've had within the last 6 weeks.
