Question about Proview PL 566s 15" Flat Panel LCD Monitor
My monitor is nothing but trouble. after about 1 hour of use it starts to flicker white lines and the all of the sudden just a sold bright white wall. it is proboly an overheating issue and it is not hot in my home. If i let the monitor sit off for 10 min then it works again. In the mean time im getting spanked on a game or cant do my homework. Lame.
I'll be perfectly honest with you...
You're here in a tech support forum about a monitor. This is the kind of issue that we would either reach for a screwdriver and a solder iron for...
...or tell you to buy a new one.
Being as we don't have the physical capability to do the fore, I'm going to tell you that you're probably just better off starting to look for a nice flat-panel, widescreen LCD monitor for yourself.
It's always been my experience with monitors that when they start doing crazy things like that...they're pretty much on their way out and there's nothing you can really do for it all.
In fact... I have occasionally isolated the issue on a few rare occasions where a certain part was the likely cause. After looking at the cost of replacement parts, it was actually more cost-effective to buy a new monitor altogether. (Go figure on THAT, eh?)
Then when you add in all of the trouble you go through to perform the replacement operation...
No. It's just not worth the trouble.
I'm sorry. Wish I could help more than that, but I just don't think that anyone here is going to be able to assist you with this one.
My best guess as to the cause? The inverter for the backlight could be malfunctioning. The inverter in LCD monitors is the power module that powers the cold-cathode tubes behind the LCD panel that shine light through it. The inverter eventually goes bad after time... It'll either dim or start to do crazy things like overload the light tubes and such.
Or perhaps the color matrix circuitry is going nuts and sending all-white signal to the LCD panel.
I could make some recommendations on a good monitor, though. That much I could do.
At this point in time, I'm recommending Samsung screens. But to save a little money, I would point you to an Acer next.
NewEgg.com is great for finding a new monitor, though. You can find great deals there plus TONS of reliable reviews on various models.
Anyway... Sorry to hear you're having so much trouble. Good luck otherwise.
By the way... Please don't rate me poorly for this post. I would much rather you don't rate me at all. I did what just about anyone here is going to be able to do. That's all anyone should expect, right?

Tips for a great answer:
The power printed circuit board is failing, not
delivering the proper power to the main board and/or the back lamps. One can
have this board repaired inexpensively by a electronic technician. Email me at Sprint6@zoominternet.net
and we may be able to get your unit working properly again.
