Propeller/lcd monitor problems

I have a few job display boards where I work.· One display that has been in action for about 10 months is now started to act funny.· If I hook it up to my laptop it will work all day.· If I connect it to the job display box it will work for a while then the screen goes black.· I replaced the prop with a new one and it still does it.· Anyone ever have any similar problems with a prop/lcd monitor system?· Is it just the monitor just going bad?· Thanks for any ideas.

    1.Check the Xtal freq or just try another Xtal.

    2. Could be a bad voltage regulator. Check the voltages on the prop chip before it goes dead and then after.

    Another possibility is a piece of new equipment that is putting a glitch into the system via the mains supply.

    Sound like a power supply problem... Maybe an overheating voltage regulator?
