Dead pixels and hot pixels

Before choosing my new camera i remembered reading something about the Canon 5D mkII having firmware issues.I assumed this had been sorted by Canon as this camera modal was 3 years old now.I had joined groups on face book and not seen any negative comments regarding this.Also when deciding if to buy the full frame monster 5D mkII or the crop sensored 7D.I did my homework and read customer reviews .Nothing mentioned about this subject.On receiving my new camera i was delighted with my purchase.My photography had come on leaps and bounds since i got it.A couple of days ago i started to notice a red dot on my new LED computer monitor.I was 2 seconds away from ringing up PC world to go mental about the duff monitor they sold me.When i  decided to check the facts before i make a pleb of my self on the phone.The red dot moves !!!!.

What ? It couldn't be ? Could it ? Not my new camera surely something isn't up with my pride and joy new toy ? IT bloody is ! I did a bit of research on the net and found that its still a problem.Dead pixels and Hot pixels. GUTTED !!!! to say the least.I found a site on the net that boasts it can fix this problem . to check you have dead or hot pix .Turn the camera on, Leave the lens cap on and dial in a 30 second exposure and fire .Repeat this at different ISO's.If you find you are suffering from said problem an easy way to fix this is to set the camera to perform sensor cleaning mode manually (NOT AUTO) for one minute.You only execute the function<Not exactly performing the whole sensor cleaning procedure.Magically,The sensor cleaning task should  shake the stuck pixels off,If not,Repeat a couple of times more until it does .If still no joy its time to call Canon.I have tried this procedure 4 times.i have read also that its only seems to be a problem in jpeg not in RAW.I have tested again in Raw and I'm still suffering .The annoying this is its not every picture i get this problem .and i never really noticed the problem till a couple of days ago.And while i thought it was a problem with my £120 monitor it didn't really bother me that much .Now i and fully aware its a problem with my £2300. camera i am to say the least pretty pissed off.I will continue to try this procedure and hope for the best.I will also continue to research this problem to see if there is a firmware update that fixes this problem .If not i will call in the guys in white coats at Canon .
