Default LCD Works then goes white..



the Viewsonic VE500 is well known for bad caps ... but you do need an esr
meter to check them as ive seen different ones go bad in these .. so to
recommend to you which ones to replace , id have to say damn near all of
them without you using a meter ! .. get a meter or shelf it until you can
afford one


cheers

I just got another LCD that doesn't work right..It is a Viewsonic VE500

and
I'm acutally using it to type this message, but sooner or later it will go
white. When it does you can shut it off and turn it right back on and it
will work for a short while again or sometimes a long while before going
white. Could it be capacitor related or is this more likely some sort of
logic chip. There are no artifacts on the screen when it does work, so I'm
at a bit of a loss since there is not LCD repair FAQ that I can find. I
guess that is due to these things not being designed to be fixed.
