Hi All, I've recently purchased a Sony 1272QM pj. I think its brilliant but also needs quite abit of work until i'll be happy with it. I've cleaned it out thoroughly so there is not dust or dirt to be found inside, i've replaced the green tube so that both red and green are in excellent condition and have hopefully secured a blue one to replace the useless blue that is in there at the moment. Whilst i'm waiting to see if i get the blue tube and also save up for a board to give me prog scan component inputs i wanted to change out the fans. Its abit of a noisy thing at the moment and i can hear the fans are starting to sound a little gritty. I could open up each fan and individually clean and oil each one but its a pain and doesn't always give the required result so i'd like to buy a set of new dual ball bearing fans. I belive there are 5 80mm and 1 40mm fans in the 1272. I've plugged in a regular 3 pin 80mm fan (after changing over the red and yellow wires to make sure the fan runs) but after a second it shuts down the whole PJ. Are they're any quiet direct replacements or some way to shut off the fan speed sensing circuit, the latter being better.
