Thermaltake DH101 + backlight of LCD in standby

[cokker]

Hi

I have bought the above named case and everytime my pc goes to standby the lcd backlight turns on again. I don't think this is intended behavoir. I'm using VDR based on Linux and the display works fine and is turned off during shutdown. But afterwards backlight comes back.

Do you have a solution for this? Perhaps there is a way to tell the lcd to stay off. Do you have some documentation how to implement such a feature?

If you need further information please ask.

Good luck with that.

Exactly the same as the Antec Fusion LCD. Turns itself back on when the PC shuts down, the only way to get it to stay off is to disconnect the computer from the power.

Very annoying, I asked Soundgraph about this several months ago.... got a response telling me to check the tickbox in iMon that turns it off when shutdown, even though I'd already explained this was ticked. Nothing since then, now they simply refuse to respond to emails on the subject.

I await their response to your thread but I wouldn't hold my breath. You can see many many other people have the same issue on many cases, check the old soundgraph forums under the OEM section.

Dear All,

I think this problem doesn’t happen to all system and may come from the power instability of M/B while shutdown and stand by.
We have tested it in our test lab but failed to re-produce this problem.
Please let us know FW version and what kind of main board you’re using.
You can check FW version in iMON Manager>Options>Version/Update.

Nope. I have two cases with Soundgraph LCD's. One is much older Blue on Black (Blue on Blue in reality), which does turn off correctly regardless of the motherboard in use, and a newer White on Black (Cyan on Pink in reality), which does not turn off using the same motherboards.

Motherboards tested with both LCD's are:-

Asus P5E
Asus P5E-VM-HDMI
Asus P5W-DH_Deluxe

The old LCD works as expected, the new LCD's don't.

The problem is without doubt related to the newer LCD's, and is in no way connected to the motherboard in use.

I cannot tell you the firmware of the newer LCD, because all I have recieved have been returned as obviously faulty, both in terms of their operation (won't turn off) and because they all look terrible and bear no resemblance to the images shown on your site.

Hi

I have a rather old Motherboard Asus A7V133 and my display firmware is 0x3802.

Some users reporting that the display is stay off when using windows. With Linux it don't work. There is a driver available but I think it is missing a special shutdown sequence. Perhaps you can tell me how this sequence has to look like. So I can send them to the display manually.

Thanks in advance

Dear Sven,

I’m really sorry for your inconvenience.
Currently we don’t have enough time for testing this issue because we have to release the update for Windows 7 and our new product till the end of this month.
I think we can do this test intensively from next month.
Please wait for while.

Any news on this problem???

Dear All,

We’ll check this problem in this week and post the test result on this thread. Currently we think this issue is related with power management of main board.

I’m really sorry for the delay. Please wait for a while.

I Know it sounds wired, but I have noticed that when my tv is on and the HTPC is turning off, the display stays off, when I turn off my tv the display turns on.

When my tv already is off when the htpc turns off, the display turns on immediately.

So my display is always on, when my tv i off, and it is off when my tv is on, until I turn it off

Mainboard: Intel DG45ID
Tv-connection: HDMI

Hope it helps you when testing :)

[mailand84]

Done some more testing...

It's my Tv/HDMI that is the problem.

If I take out the cable before i shut down the display dosn't turn back on.

With my mythbuntu installation and a ASUS M4N78 board I experienced the same problem. My solution is that I don't shutdown to S5 but S4 and switch the light off
by sending some code to the lcd device inside the sleep cycling scripts.

perl -e 'print pack "H*", "8800000000000088"' > /dev/lcd0


This works pretty well, until you power-cycle the box.

Any news about that problem?
I use a Silverstone ML02B an I have the same Problem. If the system is suspended, the backlight is off. But when I shutdown the system, the backlight is on.

Perhaps soundgraph can post the sequence that must be send to the Display to turn off the backlight. In the iMON-Software under Windows there seems to be a Option to do this.
But I use Linux.
MB is a Asus M3N78-VM, System is Ubuntu.

Hello all!

I've got 2 Thermaltake DH202 mediacenters in my setup.

When shut down, one PC swithces it's backlight off as supposed to, the other PC switches it off during shutdown, but it lights back up when the PC is fully shutdown... Same issue as described earlier in this topic.

Both systems have an Asus P5Q-E mobo with both a Corsair VX450 PSU. both are via HDMI connected to a monitor and a beamer.

Any news on this issue?

Hello jhonny.hur,

unstable Power is not the reason (in my case).
I tested it with a fresh XP installation, the Display gets dark at shutdown and stays dark even the machine switches off.

With my Ubuntu with ImonLCD 0.0.5 the display switches off an the Backlight turns on when the PC turns the Power off.

It would be nice if soundgraph could help the community to get rid of this Problem.

Hello,

I bought this case and installed in it MB ASUS: P7H55-M/USB3, and also have this bad error - when PC is in standby, or when I shut down backlight is going down, and after 3-5 second in ON again.
I was search a solution for wely long time in my case I made it.

What I done? I was connected LCD dispaly to external USB port - not internal in inside.

Also what I saw - when LCD was connected to interal USB, all USB ports after power OFF PC - external or internal was ON, but when LCD was connceted to external port [no matter it was 2.0, or 3.0] all ports was been off.
This I was checked by connecting my PDA to all ports and watched is PDA charging or not.

So my assumption is: ASUS have something wrong with them MoBoS.
[Sorry for not perfect english, but maybe someone have this error to and find in here solution.]

[Sorry for not perfect english, but maybe someone have this error to and find in here solution.]Your assumption is wrong, it is just a soundgraph LCD design bug that they won't fix (no firmware update possible !!!), you will learn this here SoundGraph don't care about us.

Welcome to the "i bought a buggy LCD" club :mad:

I just bought me Thermaltake DH101 and after sleep/hybernate my lcd screen goes off.
