CrossOver 27Q LED/LED-P, 27M LED, & 2720MDP GOLD LED Monitor Club - Page 509

post #5081 of 6483
Just received mine today and have am looking at it as i type, I am so relieved to say... this monitor is flawless. No dead or stuck pixels... No backlight bleeding... And setting it up was effortless. Well.... not all of it was. I had to squeeze my hand between the monitor and the base to connect the adapter and dvi.

But I digress... biggrin.gif

Hello,

One of the things that worries me about buying one of these is : what happens 2 or 3 years down the road if it dies? I'm sure I'm not the only one who worries about such things. Most people seem to have good luck with them, but I see the following
occasional issues:

* Monitor died completely
* Big band of flashing green pixels
* Monitor whines
* Power brick whines
* Power brick makes a clicking sound
* Monitor won't stay on.
.....etc.....

Now, I used to be a bench tech. That is, I fixed electronics for a living. I am reasonably confident that I can take care of
most things if I have the following 2 things:
1. Info ( schematics, parts lists, etc )
2. Access to spare parts

For grey market Korean stuff, I don't expect to ever have access to #1. What about #2?

Here's an ebay listing:

http://www.ebay.com/itm/Video-driver-board-repairing-backlight-Crossover-27Q-monitor-and-etc-/111016273461?_trksid=p2047675.m1850&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D14294%26meid%3D5772922325718900974%26pid%3D100011%26prg%3D1095%26rk%3D1%26sd%3D111004092960%26

Now THAT's interesting. The LED driver board is probably the hardest working board in the monitor - that is, it handles
real power. Experience shows me that the higher the power, the more failures.

It's interesting also that the listing is in Russia. I've been there. I've been to the Moscow radio flea market. In Russia, they
fix things. Things that we would throw away. It's a tradition from communist times, when "things" were more valuable than "money".

A few years ago, I had a (IIRC) Viewsonic monitor that would turn itself off. I traced it to a transformer with an arcing coil in the backlight driver. "Traced" is actually an exaggeration - I just looked at the board and saw the burned spot. This monitor was
quite fixable with a new coil. I read the part number off the coil, and searched high and low. Found it on a Russian website
that unfortunately only dealt locally. I sent them an email in Russian - no answer. Then I found another Russian website
with instructions on how to rewind that exact coil. Wire size, how many turns etc. So I still could have fixed it.

Unfortunately, in the meantime we had to move, and there was just no time to deal with it, and it went to the recycler.

Maybe I should buy two of these things, enjoy dual-giant-monitor bliss, and know that if one dies, I have the other one
as a spare parts source and example ( of one that works ). With an example like that, one can often fix things without having
schematics. Been there, done that...

Its like anything you buy. IF you bought a regular monitor from Sasmung you get a 2 year warranty. IF it breaks down after the 2 years its over with and your done. You don't get to buy seperate parts nor do you get to fix it unless your capable of doing so.
There's really no difference from them and these monitors. Your given the 1 year warranty via seller in case something does happen. Quite honestly if something happens within the first year something was wrong. IF it passes the 1 year mark your basically good to go.
All things are replaceable if given the research.

Example:
The PCB on eBay that's being sold in Russia. If I remember correctly the guy bought the monitors and extra PCB's. Sent the monitor back and had just kept PCB's. He's now trying to sell them. He posted on this thread awhile back so you gotta go back a good amount of pages.
Could be wrong but that's what I remember cause he posted the exact link and I complained saying why pay that when you can get it free from your seller.
You also now have the complete PCB set from Overlord Computer's.

So there's plenty of options to do some internal fixing. Which isn't really applicable for other monitors unless you know exactly what part it is and where to get it.

Still, that Dell monitor is not a bad deal. I was looking for a welder a few years ago. I considered a Chinese machine. Kind of like these monitors - very cheap, a lot of capability for the price. But no support, no schematics, no parts. If it dies out of warranty, you are SOL. I wound up buying Miller TIG and MIG machines for that exact reason.
For a monitor that has support for multiple inputs, the Dell is almost competitive in price. Thanks for pointing it out.

I wouldn't say that. A quick google search for a part number or the monitor will probably bring up parts or somebody selling dead monitors for parts.

When my 30" Samsung 305t+ started going, simple search for the cause of the problem and quick tear down showwed it just needed a new lcd controller board. 5min ebay search and $300 later monitor is like new again.

Most things you are bound to find parts for unless its some really obscure item.
post #5086 of 6483
Sorry but the Korean monitors are NOT the same as the name brand monitors. There is more to a monitor than the panel. Most of the name brands come with good 3 year warranties for a reason, they use better parts. Actually you get an extra 4th year warranty with most credit cards. Plus they have buttons and onscreen menus that actually work, along with better stands.
post #5087 of 6483
I do see a lot of comments stating these monitors are different from brand monitors in terms of quality. I can really say the warranty is truly a bit short but even some name brand monitor do only have a 1 year warranty unless a longer one is purchased (which in some cases can be done here too). I would point out that from the last comment that "better parts" is very subjective. I have owned quite a few name brand monitors in my line of work and can really say that all brands have there equal set of downfalls (with varied degrees). For example i have always had a bit of problem with light bleed on asus monitors and stand issues with LG. It is really a toss up from monitor to monitor and brand to brand. To isolate these Korean monitors out from that overall truth is a bit folly. To further this, at my house and at my office including my agents monitors i have first hand experience of 14 dell monitors, 5 asus monitors, 11 hanns, and 3 LGs. Just about all the dell monitors have and developed a dead pixel over time or at purchase (i just tested them all yesterday for this sort of review). The Asus monitors ALL have backlight bleed. The LGs have less to be desired stands and really the Hanns have various issues with colors. This is a bit subjective as they are in an office environment and a lot of them have had quite a bit of movement/abuse.

The point is that there are a few tradeoffs to getting these monitors but they are not be any "default" a lower quality or class and remain the best monitor i have seen next to the thunderbolt display (which i have a friend convinced to side by side compare in a couple days smile.gif can't wait)

I am hoping this doesn't rough anyones feathers but at 1/3 the price of the thunderbolt it is still the best deal out there by far if you do your research and buy from a reputable seller.

On a side note for anyone that gets the blade edition crossover debezeling was not quite a success due to the size of the bottom of the panel being wider than the rest. It may still be beneficial for those in landscape but i am a bit of a portrait guy.

I've been reading through this thread, and I've decided to pick one of these up. There is just one thing that needs to be decided... the seller.

acessorieswhole or dream-seller? I'm going for the 27Q LED-P

Haha, I was leaning towards this after reading so many good things about them.

I did it! I'll post how it goes when it arrives smile.gif
