20 Most Recent Proview PL 566s 15" Flat Panel LCD Monitor Questions & Answers

The simplest test would be to try another monitor. If it shuts off, the graphics card is overheating, or the PS in the computer, or the processor. If the result is that everything continues as it should, the original monitor is overheating or otherwise failing.

Type in the model number or serial number on the back of the power brick into Google and you should get an Amazon page.

This happens when no signal is received by the monitor.
Most of the time this is a problem with the VGA. It could be a problem with RAM also.
If you can, remove the VGA card and RAM(s). Clean the VGA slot and RAM slots with a small brush. (You can use a blower also, but I prefer the brush).
Re-insert the VGA and RAMs.
Restart the machine and check.
If this doesn't help, you may have to replace the RAMs or VGA.
Good luck!

YOU can easily get it from any computer store and please contact the concerned person from whom you bought that monitor for clarification regarding the non availability of LEAD WIRE and also see teh box in which monitor was there , accessories present at the time of purchase would also be given.
try that you get it for free from the person or the organization from where you bought that monitor, otherwise you will have to purchase a new lead for your monitor

It is tricky to see, its at the back and you may find it easier to see it if you turn the monitor upside down and look at it that way.

beware its aliens!

Now for the srious comment.. The convergence gun needs repplacing. Not a DIY sometimes called the color engine. It needs special tools to retune it once its replaced so dont attempt like many others have done and try and repair it yourself it will end up costing 3 times as much.

raeda70, No, No, No, This is not the way it works at fixya!! Start off by telling me when you got the monitor and how old or new it is. Then tell me how it was working yesterday or the day before. Tell me if monitor is still covered under the manufacturers warranty. Monitor must be working now!! How else did you get to do this post on fixya? Did you do the flashlight test that every "cold-cathode-fluorescent lamp" back-lit lcd monitor owner should do when their lcd panel goes black or fails to turn-on? Did monitor ever display (show) the Win-desktop screen? If monitor worked before, and it 's not working now, then it's probably got an internal problem with it's "switch-mode-power-supply/CCFL inverter supply and will need you or an electronics technician to troubleshoot and repair it. Read my fixya profile and those of other lcd monitor tech's here on fixya to see if DIY fix is something you want to do. Do an additional comment with more info after you do some reading and can give more detailed "symptom" description. I want to help you. 12fixlouie north of Windy City

Chances are that you are not hurting anything with the lower power supply. What is probably happening is most likely two fold. 1. The light bulbs in the backlight circuit may just be wearing out and need replacement, and 2. the lower current power supply may not be capable of producing al the current that the monitor needs at certain times during operation. I would suggest getting hold of the correct power supply module and see where that gets you. If you still have the red outs,replace the light bulbs in the monitor. The only other fault than that would have to be in the video controller. Hope this helps.

Hi, If no indicator lights, no reaction when push the power on button, then chances are that you have a power supply problem. If your particular brand/model has a built-in power supply then it has to be opened up and diagnose. Normally most units would show a light indicator by simply plugging it into an outlet. That light changes color or another one lites up when the power on button is pressed. Absence of the first light indicator means that the system is not getting any power at all. You would be better off seeking the services of a qualified professional. But then again, it just might be the power cord which is of course relatively easy to replace. Try using your computers cord first for the monitor if it fits and matches. Hopes this work out for you and give you an idea or two. Pls post again how things turn up. Good luck and kind regards.

Most common problem is inverter board.

Proview PL 566s... | Answered on Nov 07, 2008

One or more of the Cold Cathode tubes that illuminate the lcd backlight may be bad. i have the 19" and it has 4 - 2mm X 400mm tubes (two at the top and two at the bottom). One of them quit so to test it out i temporarily replaced it with one from my pc and it started up fine. You can order from:
But ONLY if you have knowledge of electronics, patience, a steady hand, and fine screw driver set. (oh and latex gloves in a dust free environment.) You don't want to get the screen layers back together only to find some hairs or dust specks light up when you turn the lcd on!
btw: The tubes are as small as the ink tubes in a ball point pen and can snap very easily...

sounds like a color balance issue. Check the menu, do a degauss...and then check for the color temperature (reset for default)..

Got backup?

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?
