What happens if I use a disinfecting wipe on my LCD monitor?

Q. I used a Lysol disinfecting wipe on both my LCD monitors while they were turned on (yeah...I know it was stupid) and now neither monitor will work.

To add to that, my G5 Power Mac, which was connected to the monitors at the time, seems to have frozen and won't respond to anything. I've tried unplugging it for 20 minutes and although when I plug it back up, the power indicator on the front is on, there is no other response.

Help!!!!!!!!!!!!!!!!

A. Lysol is mostly water with a little alcohol and ammonia

You may have zapped your Monitors, Graphics Card,Motherboard and/or Power Supply

You will need to test each thing in a good system
Or take it all to a shop and ask what's fried


Can I use old capacitors to repair LCD monitors?
Q. I am fixing an LCD monitor (needs new capacitors). In an old VCR/DVD player there are some with the exact same voltage and uF rating. Can I use them?

A. Don't use old electrolytic capacitors. They have a tendancy to dry out and go bad. If the old capcitors are not electrolytic, then they would probably be OK, but you might test them to see if they are still the rated capacitance.

What is a good camera for a beginner Photographer?

Q. My aunt got me a cutesy digital one but it's not rechargeable, which is a real pain. Plus the zoom sucks.

I want a camera that can catch the sunlight in the morning dew. I don't have much money but I can always save up.

A. I recommend to anyone seriously contemplating the purchase of a new digital SLR camera to consider these two primary questions:

1. How much money do you have to spend????

2. What level of photography do you aspire to "progress to" in the coming years ? (i.e. basic beginner, intermediate, or professional/business use).

For most beginners to intermediates I usually suggest one of these two manufacturers: Canon vs Nikon

1. Canon EOS Rebel model XSi. (Also known as the Canon 450D in Britain)
The "kit" package comes with an 18-55mm zoom lens. The camera has pop-up flash, 12.2 Megapixels, and shutter speeds up to 1/4000th, 100-1,600 ISO sensitivity, 7 autoexposure Scene modes, PLUS Shutter Priority, Aperature Priority and Programmed Exposure Modes and Manual. It also has a 3 inch LCD screen, 3.5 frames continous per second max., 9 point AF system, Live View Functioning and the ability to record photos in 3, 6 or 12 Megapixels PLUS numerous other great features found only on more expensive cameras. Wal-Mart is also selling them now for about $799. Sam's Club also has them for $729.

I bought one of these 6 months ago and use it as my "back up" camera. I absolutely love it. I have gotten some fantastic photos with it and cannot praise it enough. I routinely enlarge my photos to make 8x10's and 11x14 size enlargements with no noticeable distortion or loss of detail in the pictures.

2. Nikon D-90: If you prefer to use Nikon equipment I strongly recommend the Nikon D-90 which has 12.3 Megapixels, 3 inch monitor with Live View, 200-3,200 ISO sensitivity, 11 point AF system with Face Priority, 4.5 frames per second in continous mode, 5 advanced Scene modes for auto exposure plus Shutter Priority, Aperature Priority, Programmed Auto plus Manual. The D-90 sells for around $900-950. (Body ONLY. The 18-55mm lens cost an additional $150.-175.) Typically, Nikon equipment is slightly more expensive than Canon equipment, but (having owned both Nikon and Canon cameras), I have seldom noticed BETTER quality results using Nikon equipment.

You might also consider the Nikon D-40 ($499) kit that comes with the 18-55mm lens.
Another great choice is the Nikon D-60 kit ($649) which also comes with the 18-55mm lens.

These selections are probably the best choices for any beginner to intermediate skill level, offering the most lenses and other accessories, dealers and places to purchase.

I strongly recommend that ALL beginners buy a good book on digital photography AND take a class or two from a Vocational school or Community Education Center in your area.

You can learn more about the technical specifications of each of these two cameras at these websites:

Good Luck
