Just bought a Sony VPL VW200 which is supposedly completely dead, no power at all. I know its a bit early to ask for help since I don't yet have it, but I wanted to see if you, MT, would possibly be able to scavenge some service documents for it? |

Hey MT, Does the VW200 have a switch for the filter cover? This VW200 is missing its filter cover (as I saw in the photo when I bought it), it didn't "click" until just now when I remembered my old sony projector wouldn't power up because the filter cover was slightly ajar on an old sony PJ...

Yes, there are 2 lamp cover switches and 1 filter cover switch.

Thought so, I just received the projector a few minutes before your response, I checked it just now by depressing the switch with a Q-tip but its still dead as a doornail.
The projector has the lamp cover the lamp and all that fun stuff so its complete minus the filter cover. I took the bottom "Input board" cover off first expecting it to be the lamp cover. When I did that I noticed that the area right by the inputs has slight "rust color" around the inputs, and the bottom of the PJ has water spots on it like the previous owners ceiling leaked onto it.
It appears to have leaked right over the PSU, since when I pull the top blue/lamp cover forward to expose the lamp section, you can see slight rust/corrosion right over the PSU section on the bar that the blue cover slides along.
Hope if water is the reason its dead that it didn't destroy anything major... I suppose I need to start by taking it apart, but I honestly don't know where to begin on this machine, don't suppose that Service manual has a disassembly section I could use? lol

Wooo, looks like fun! I'll get back to you later tonight or tomorrow (whenever I get it apart enough  ) and let you know what I find from a visual inspection. |

So this is why you do NOT NOT NOT NOT put a projector on a ceiling, right under a water pipe/dishwasher:  Obviously this is why it won't turn on:  And this is probably why the fuse blew, luckily it appears the boards themselves aren't really damaged, the cheap tin covers are what seemed to have rusted out mainly:  |

What a shame. Keep us updated.

It just keeps getting better and better  So the good news is, the light engine appears to have not been touched by water at all (close but not quite). So that's good, I cleaned several connectors and removed as much corrosion and rust as I could from the area and then put it all back into the machine. I saved the GA (PSU) board til last since that I suspected would have an issue... Boy was I right unfortunately:  This will be quite a task to refurbish:  |

I don't suppose the VPL VW100 uses the identical GA board? This thing is pretty rough, not sure my skills are l33t enough! |

Well they carry a different part number and a couple of the connectors are a little different but they look to be the same other wise. The connectors that are different just carry an extra gnd line. Easily adaptable.

That's good to know. I did clean the bottom up a bit (still needs a bit more cleaning) and it doesn't look AS bad now. One foil is blown right off the board about 1/2" long, theres an 8 pin IC (A6169) near it, a small transformer, and the foil is blown off is between C200 and JL208. Ther's also a flameproof resistor soldered in right on that foil and also a 50v 4.7uf capacitor that's blasted out the bottom. That's just the visual inspection... Ill take another pic of it cleaned up, but im curious, on a 1-10 scale, how repairable do think this PSU is? |

I have not heard anything yet that would make me think it is not repairable. |
