I started to get a few stuck mirrors on my DLP chip. They are slowly accumulating. Maybe one or two new ones a week. For the last 2 months. I was getting ready to order a new chip when they get annoying enough. ( almost there ). But now I have another problem. 3 or 4 times in the last month when turning the TV on, there will be the start-up chime, center blue logo is illuminated, but screen is black/off. Sound will work. 3 LEDs on front panel are not lit. Power the unit off and back on, and its fine, and has no other issues for a week or two.
So, is this a sign of something else about to fail? If so I probably will not bother fixing this TV anymore and just let it die when it dies and put up the working parts for sale.
I have previously replaced a blue LED (Twice) to find out it failed originally because of a faulty driver board, which I also replaced. When I did that first and 2nd round of parts refreshes, about 1-1.5 years ago,I also cleaned everything out ( fans/heatsinks ) and also replaced the old thermal paste sheets with arctic silver stuff. I did this on the 3 LEDs and the DMD/DLP chip.
So do I keep dumping money into this set? Or get ready to get some new hopefully not mediocre LCD setup?
