HLM507WX 3 Lights and shuts down
Posted: Thu Jun 11, 2009 4:43 pm
I have a HLM507wx/xa 50inch dlp. Bought in 2002. In 2004 color wheel and lamp replaced by authorized samsung technician.
A couple months ago Tv started turning making a slightly louder noise when starting up. Not the same screetching and buzzing it made before the color wheel went bad, but what sounds like maybe the fan or color wheel working harder. A few days later the TV screen went black and the three lights began to flash. I can't get it to turn back on without first unplugging it. Sometimes after the unplug it works for 5 minutes other times it works for several days. Manual said it was time to replace bulb. I made sure to purchase the same original toshiba series lamp that was inside and replaced it. TV still randomly shuts down gives me the 3 flashing lights. I've reset the lamp counter, vacuumed the inside of the cabinet and blew away all the dust, and re-taped the safety switch (it was still taped up from the service call back in '04) But It still does not function properly.
The picture looks fine when it turns on, in fact there is no noticeable difference between the old and new bulb. There are no clicking, popping or other strange noises beyond the slightly louder whirling noise. And I've discovered that even it it shuts down after 5 minutes, I can unplug it and immediately plug it in again and it may work for another couple days.
Any ideas or any other things I can check before randomly buying more parts?
