Thread: Dead LCD monitor
07-18-2008, 10:56 PM #1Dead LCD monitor
I have a Proview 22 in monitor, model PL2230WDB which seems to have died.
The power button slowly blinks blue and the screen stays dark.
I've tried it on several different computers so it's not the video card.
The ONLY thing I've found online is something about changing some capacitors on the power board.
Did that, no joy. Don't really want to send it in and there's nowhere close that could check it out.
Of course it's warranty is up.
Does anyone know anything about these monitors? Is there some kind of reset magic with the switches?
Or am I just SOL? I have another 20 in connected so it's not an emergency or anything.
Bought it as a replacement. Would be nice to have both connected tho.Delusions are often functional. A motherís opinions about her childrenís beauty, intelligence, goodness, et cetera ad nauseam, keep her from drowning them at birth.

Just a shot in the dark here (no pun intended), but did you by chance check to see if the backlight was OK? Some LCD monitors will act exactly as you describe if the backlight goes out. Very often the backlight is the first thing to fail.
If you can get hold of a schematic for the monitor which will give you voltage readouts across the power supply, you may be able to check them to see if the monitor is receiving power.

There are specs for voltage printed on the circuit board.
How exactly does one check the backlight?
And is it really worth fixing/replacing?Delusions are often functional. A motherís opinions about her childrenís beauty, intelligence, goodness, et cetera ad nauseam, keep her from drowning them at birth.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

I am not being funny but I am qualified and I have still made mistakes and ended up getting a major jolt. Mains power is not to be taken lightly.
If however you are talking about a low voltage power board then by all means continueExperienced computer user, applications programmer and component level service engineer but came to the Apple platform with intro of intel!. Pro-photographer and director of electronics company.

Not taking it the wrong way but just to let you know, I've built power supplies from scratch for other projects. Mostly regulated 12v, 3 to 10 amp to power radios. Been zapped before too.
Was asking here in case it might be something on the video board which I don't know anything about. Haven't checked any voltages yet because the way it's put together, I'd need about 5 hands to hold things up and away and not sure it's really worth the trouble.
From what I read, it might be a problem with sleep mode. However when it's in sleep, the light turns orange. Right now it just blinks blue.
Thanks for the replies.Delusions are often functional. A motherís opinions about her childrenís beauty, intelligence, goodness, et cetera ad nauseam, keep her from drowning them at birth.
