I asked because I am looking at the schematics and this is how you narrow down where a possible problem is.
1)Are you selecting the S video input again after it did not work? 2)Have you tried the video mute button? 3)Do button pushes/selections show up on the screen or only the menu when you select it? 4)Have you tried any type of reset?
1. yes, it tried all connections 2. this is what made it work. 3. menu and input selector were all fully operation, but no video 4. no
so, what happened yesterday was, - i switched it on, s-video connected to satellite box - no picture, even when i went through the inputs - the video was unmuted at this point - i hit mute, confirmation on screen that video is mute - i hit mute again, confirmation on screen that mute if off. - voile, picture.
So, no clue, other then, i disconnected a bunch of stuff and connected it again and pressed some buttons.
Note that I am still worried that last weekend the picture showed a vertical black bar on the right side, there were some thin horizontal lines for a sec, and then the video cut out. my wife thinks that was because of a loose cable, I am not so sure.
anyway, we watched the full Warcraft movie (surprisingly entertaining actually ;-)) and no problem.
Any more thoughts? A loose connection and user error?
I would recommend reading my VPL-VW10/11/12HT thread here in the digital projector forum. You likely need to recap your power supply as these Sony projectors are over 11 years old now, and the capacitors are beginning to lose their ability to charge/hold the charge. The power supply in your projector is identical to the one I repaired.
- black outs continue to happen, but can be fixed by tapping the tap of the case or jingeling the connector panel
- screen shrinked horizontaly, tapped the top of the case sharply with the nail of my finger fixed it 3 times - screen blanked out, pushing, tapping the connector panel briefly fixes it. - this is after 30 min of operation.
besides the power supply and caps, could this also mean broken solder connections on the board, that interrupt signal when the unit heats up?
