If they could be so kind to give me information on how to solve a problem with my lattepanda.
The question is that it does not send signals HDMI starts normally but then the red led simply stays on does not give HDMI signal.
Already try the method of resetting by pressing the power and reset buttons but simply still not working. If you turn on the board but do not access the operating system or simply do not give HDMI signal.
If they could help, I would appreciate it.

HI there
There could be a few reasons as HDMI settings vary between devices.
As a first step I would recommend checking a few different HDMI devices to eliminate the problem that end.
Also, do you have the DSI 7" screen kit you can check with to see if there is signal coming from the MIPI interface?
Secondly, if you are able to get a visual output you can double check the settings in the bios. You can access the graphics settings by going to Chipset > North Bridge > IGD LCD Control

I am replying to existing thread because I have same issue. I bought LP few weeks ago and suddenly today it stopped to send HDMI signal.
I tried with different cables and different monitors and it still doesn't work. Also tried reset with holding reset and power button but nothing happens.
I don't have 7" screen so is there another way of fixing it or getting into BIOS or something?

When I turn it on red LED is always on. It blinks only when I hold reset or both power and reset. Blue LED blinks few times at start and after that is also always on.
Any further suggestions? Thanks

Is the red let always on after you re-flash the bios?
Did the red led goes off before?

Yes red is always on. I don't know if I re-flashed bios because I don't get visual feedback.LattePanda wrote: ↑Tue Apr 17, 2018 9:24 amIs the red let always on after you re-flash the bios?

I put USB with bios files for re-flashing but can't see anything.
Also, I ordered 7" touch screen and connected it today but all I get is black screen so wrong video output is not the problem.
Any idea where is the issue?
One additional question. Is there a way to restore files from LP in this case? I have some data on it that I don't want to lose so can I somehow connect to LP storage?
And, if we don't find solution, do I need to send a video or something to verify the issue?

Hi, if the RED LED is always on, there is reason to believe the BIOS has missed.
You can follow the guide below two re-write the BIOS.
viewtopic.php?f=6&t=386
And don't worry about your data if the board can be solved by the solution above.
But if not, not easy to say!
