Re: Hanns-G HG281D, LCD Monitor no power
So I made some unsuspected progress with my hd281D.
long story short:
i didnt get any input on hdmi or vga with different pcs and cables.
After changing all the caps on both boards the problem persists.
Now the news:
i just got a Fire Tv Stick and tried it on the broken monitor and voila. There is a picture! Its not the best quality and the maximum resolution is 720p, but atleast there is some life.
So I tried the Stick with and without extension cord and both is working in 720p. (1080p is...

Re: Hanns-G HG281D, LCD Monitor no power
Ive tested multiple PCs with different HDMI cables and one VGA cable.
None of them detected the monitor. But the monitor knows when a cable is connected oder disconnected (no signal message)...Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
What is the best way to make sure these soldering points make a correct connection?
Ive read that some guys put their graphicscard into the oven for a short time. Can i use this method with the mainboard or will the caps get damaged from the heat?
My problem is that i only have a rather large soldering iron. So I cant really solder on this small pins. i would only try to heat them i little without fully melting to give them a better connection......Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
I just saw your answer, thanks!
i got all the capacitors from Conrad here in Germany. Sadly they only provide one cap for a special rating (V and F). So there wasnt really a choice.
But shouldnt there have been at least a slightly change in symptoms after changing the caps?
Most of the people with bad caps in this thread first did have only little problems and with time they got bigger up to total failure of the monitor.
But my monitor just stayed black after reboot, it was perfectly fine before!...Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
Yeah, i checked the cable and laptop on another monitor. There they are working fine.
Thank you very much. I think verifiyng the videosignals and processor is something i cant do with my limited electrical supply and knowledge.
I will wait another week if someone has another idea. After that its going into the trash if no one is interested.
perhaps i should mention that this problem did start after rebooting the pc.Last edited by fightforlife; 03-16-2015, 11:59 AM.Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
Hey, thank you for your suggestion!
i just measured the two voltage regulators. But nothin seems off to me...
The bigger one has an input of 5.1V and an output of 3.3V.
The smaller one has an input of 3.3V and an output of 1.8V.
All voltages are stable when connecting something on HDMI or pressing on/off.
Edit: PS_On (the black cable between power and main) measures 0.02V when amber led and 2.84V when display on.... somewhere in this thread was said that it had to be over 3V?!...Last edited by fightforlife; 03-16-2015, 10:54 AM.Leave a comment:

Problem: Always get "no signal" message when connecting or disconnecting hdmi.

Re: Hanns-G HG281D, LCD Monitor no power
So, i just changed all the Caps on the Mainboard (not the Powerboard) and the monitor is still giving me the "no signal" message.
Any ideas?
Should i replace the caps on the Powerboard?Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
Hey Guys,
i just found this Thread via Google. I read some of the pager here and hope you can help me with my HG281D.
Today after updating and restarting my computer it just stopped recognizing any inputs.
Ive tested 2 Computers over HDMI and 1 over VGA. It seems to recognize when a connection is made, because it shows the green box "No signal....". But after that it doesnt show any picture and just goes back to sleep.
I never had any problem wit this monitor before!
Did somebody...Leave a comment:
