WD-57833 help needed
Posted: Tue Jul 01, 2014 11:05 pm
Brand new to the site and have some questions about my Mitsubishi WD-57833. Bought this tv about a year ago for $1. No remote and it wasn't turning on. I purchased a lamp from ebay ($38) and there was a picture but with white dots everywhere. So I replaced the chip (never did anything like this before but the internet is wonderful). The picture was amazing. But, in the last few months, the picture seems (to me) to be getting 'darker,' the set takes almost a minute to 'come on' and there's 3-4" dark horizontal 'shadow' across the top of the screen image. I've reset the set, tried to brighten it through the menu but nothing helps. So, I'm stumped. Could it be the ballast? Would it be wise to replace the lamp again (the first one probably wasn't Phillips or OSAM)? I've read about the color wheel and other components but really don't want to go in there not knowing what to look for. Not sure what to do next. Thanks for any ideas.
