My SIL's 3 month old Sharp LC40LE700M is having the auto turn-off problem as well. It powers up and then it switches off in under 10 seconds. This happened the first time two weeks ago, and the set was taken away, brought back two days ago, and the tech said "no problem, only reprogram". Today, it happened again. Have read in some forums that Sharp models that has come out in the last 18 months have problems with the AV board. Can someone confirm this?

Sharp is kinda crappy!!

"This is more of a tip than a complaint about Sharp tvs, which have a life span of a Chinese light bulb. 1st tip, don't buy Sharp. 2nd tip, if you own a model that was released within the past 18 months, i.e., a newish model, and you are having an issue with just the red power L.E.D. flashing on and off continuously, with the tv not swiching on at all, the fault is with your AV board. (The board that facilitates HDMI, Component, audio etc connectivity). The fault is not with the power supply, back light inverter, screen scan card or other. I buy faulty tvs and repair them. I have come across numerous Sharp tvs with this problem and the only effective repair was to replace this board (Models include UK versions LC42B20E, LC42DH77E, LC46DH77E & the new LED tvs LC40LE600E & 700E). I have had over 20 tvs come to me in less than 6 months with this problem. To prove my point, I have used identical modles, swopped over each & every board to confirm in every instance that the fault was with the AV board. Trying to find spare boards is difficult unless you can get one off ebay (tv with a broken screen)"
