Two days ago I've created .mpp file for my boss. But today when opening, I've noticed that some parts of my data disappeared from it. I've no idea how to fix mpp, but I tried some ways to handle it from Google, it didn't handle my issue. I'm using MS Project 2007 on Win 7 x32.

Hi,
One of the partner I'm mostly working with, brought his Officejet 8012e, facing a problem I'm failing finding a solution.
On the Officejet 8012e, there's only one USB connector on the back, for connecting the printer to a computer.
The screen displays the following message :
"a problem has occured with one of the printer's critical system files. A printer update will be installed to fix this problem"
But even if the printer is connected through wifi to the network, nothings happen, and the printer stays idle for days.

I have a Boss DD-3 (square chip taiwan version) in my bench with a very weird problem. I found no similar problem online, nor a solution for it. It is driving me nuts.
It passes sound on bypass no problem but as i turn it on it has a constant a noise (that can be clearly shaped by Delay Time, Volume and Mode, but very subtle by Feedback).
- sounds ok on bypass
- noise is there even without input connected.
- all electrolitic caps were changed (!)
- all tantalum caps were checked, ok.
- most ceramics were cheked. too many to keep track.... -
I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down
- Problem: It started with random picture disappearing (sound still worked).

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Bypass works, direct out works. Delay signal is not right. Clock seems to be working. I replaced all 10uf electrolytics just because. No change. Based on sound and experience, should I be looking at the AD part or the DA part? I found a breakdown of how the microcontroller samples 12bit audio, I have a scope, I plan on doing more probing, just bothering me as I sit at home with it on my bench at work waiting to be fixed. If I'm reading correctly pin 7 on IC5 should be ≈ input signal. And pin 7 on IC8 should be delayed waveform? So if I have clean delayed waveform on IC8, the problem...
