Black screen, have checked almost all printed fixes

A lot of the older Canon cameras from this era use Sony CCD sensors, which are known to fail. Not all of them do, but as the remaining survivors age, it's almost guaranteed to happen on the remaining cameras like yours. The reason I mention this despite this not being a known problem model is it’s very common, even after it was “fixed” on the manufacturing side for Sony and Canon’s side.
The symptoms are deceptive at times - it can range from black images (which quickly confirm it, if the person looking at it knows what symptoms to look for), to intermittent occurrences of it up to weird focus issues which are sometimes due to a sensor that’s beginning to fail.

Yours isn’t known to fail, but it affected a LOT of cameras that used these sensors. Yours was released in 2005 so it is considered a “high risk” model. I was given an intermittent E18 S2 IS which was released the same year and is just as risky which is why I never fixed the E18 problem due to the risk of a failure putting the work I put into it to waste. I even threw a trashpicked Coolpix with a bad Sony sensor out due to parts cost, and the part being made of unobtanium.
The sheer amount of these that have CCD issues because of Sony are reason enough to skip anything from 2004-2005 unless it’s cheap, and 2006 unless you can verify it works and the model isn’t known to fail. 2007 w/ SHDC support is the ABSOLUTE MINIMUM I trust to not suddenly die.

You can replace it with a new sensor, but you will need to line up the sensor and unless you know *how* it will never be 100% correct again. For most DIYers, the best solution is to swap the lens with the calibrated CCD installed as a unit.
When it comes to cost, the problem is unless you score a super cheap donor with a good CCD (it’s one of the common problems that lead to so many of these Sony CCD cameras from ~2004-2005/6 being recycled or put in retail e-waste bins, if they aren’t used for parts), you just cannot find reasonably priced parts to replace the CCD. Your money is better spent on a good used replacement that’s years newer, or a brand-new camera from a big box store, due to the cost of good parts which don’t come up often.
