Hi. I'm hoping someone here can assist me with a problem with my rear projection TV. It's 10 yrs. old and has worked flawlessly until last night. After about 45 min. I heard a "pop" and the system shut down and won't turn back on. i could also smell a "burning plastic" type smell.
I took the back off and can't see anything obvious. If I plug it back in, two led lights come on followed by a third, then it "hums" and turns off.
I have read of problems with the C707 and E994 parts, as well as the Flyback Transformer, but would like to hear if anyone can give me some insight into this. Thanks. |

| Check to see if E994 is open is the first place to start. |

| Hi. I just checked the E994 and it is open. Is it possible to bypass this fuse temporarily for test purposes? |

If the fuse is bypasses you'll fry your power supply. Look for C707 and look for the black hole in it. |

I read through that post, and think that's probably the the same thing I'm experiencing. I checked the C707,but no visible indication of a problem. Would you suggest replacing these two parts and see where I stand? Also, do you know a good place to order them from?
The burning smell seems to located closer to the E994, actually a little left of it, as opposed to near the C707. Does that mean or indicate anything? |

| Are you sure on those specs? I'd heard elsewhere that the cap was 100uF @63v. and the fuse was 2A. Can anyone confirm because I'm going to have to match them up. Thanks. |

| Just to post an update. All is well. Was able to get the parts off a scrapped TV from a local repair store(at no cost), installed the parts, and watching TV again. I appreciate the the information available from this site. Thanks. |
