I am connecting my PC via DVI to my new LG full HD monitor and my PS3 via HDMI. Everything was perfect. Then exactly one week later, the monitor simply showed noise in HDMI [no PS3 picture] although the DVI [my PC] was fine.
The HDMI cable would not work on my LCD TV [with the PS3] either even though it did before.
I bought a new HDMI cable, and everything was great..... THEN exactly one week later the exact same problem occured and I am perplexed and am unable to determine if its a cable problem again, or a PS3/Monitor HDMI connection problem that is causing my cables to stuff up.
Both of the HDMI cables I used are very close to the PC and speakers and optical sound cables. Is there ANY possibility that perhaps the magnets in the speakers or something in the PC is causing my HDMI cables to get ruined?? Or is it likely to be the HDMI connections on either the monitor or PS3 making die.......
I am generally OK with electronics but I am very puzzled and ANY help/suggestions would be greatly appreciated.
The HDMI cable were both 3M long
There has been no trouble with the PC connected via DVI

I would first suggest that you are buying "cheap" cables.

A common speaker magnet cannot physically damage a cable unless it's physically defective to begin with (poor insulation, damaged conductors, etc.)

Did you examine the first defective cable to see what was wrong with it? (resistance checks would probably require addl. equipment)

Do you have somewhere wherre you can test the "defective" cables to see if they really are defective?

Any other ideas that I'd have would be very abstract and purely speculative without knowing the answers to the questions above.

I am taking the cables to be checked at an engineers today.
The cables are not expensive ones, but I would have thought that if there was any manufacturing damage the cables would not work at all.
These two worked perfectly for almost exactly a week each. Now they just show snow and the signal flicks on/off.
Ill get back to you as soon as i know if the cables are ok.

Sure enough, the first cable is dead, though the second HDMI cable seems to be okay. We used an HDMI cable tester and all the correct lights lit up
