DM800 - Could any of these cause problems

[GerB68]

I’m just about to set up my DM800 by installing a new Motherboard.
My last one got fried. The thing is I don’t want to make the same mistake so I’m trying to understand what caused my last board to die. Whatever the cause I believe the damage occurred to the power connector which was a bit darkish on the underneath of the board and the black plastic where the power cable is inserted had slightly melted. My box is a clone and I’ve included some pics.

Here are some of the things I did prior to it crashing.

• I was trying out a variety of new images and because of this I had to turn the box on and off. I did this numerous times. I did it by taking out and reinserting the power lead.

• I put a very very small bit of vaseline in the centre of the noisy fan. I know others do this and previously I have used WD40.

• I added a plugin which did not install correctly. It was an auto-timeshift plugin called permanenttimeshift. This gave me an error when I would enter the plugins menu. My thinking is that this would somehow call on the HDD to spin up and cause the cpu and board to overheat. The box was very hot.

One symptom before the crash was that channels kept saying Signal not found could this be the Tuner?
Has anyone got any thoughts on this?

First of all you have to shut it down before reboot using the standby button, secondly : have you tested your antena and LNB with an working reciver to eliminate this variable ?

Also you can measure the output of the DM800 to antena you will have to have somthing like 14 V for vertical transponders and 18 V for a H TP

Would this really be an issue. I mean it was working perfectly for 8 months.

Seem strange that only when I try new images and this plugin with error it fails.

Some images are problematic, also some plugins, when i've answered you i assumed that you already tried other images, if you didn't do that and try to flash one that it worked before for you

I'd say you were just unlucky, an electrical spike caused by removing and inserting the power lead caused some component to fail. It's happened to me before and I'm sure it will happen again.

I could very easily be wrong though.

Re: DM800 - Could any of these cause problems

When I was trying out different images. Some would not use my backup on the HDD so I did a manual scan for new channels. In doing this I tampered with some settings in Tuner config and I almost sure one setting was about voltage.

Could this have caused the problem?

Don't think so. Whatever voltage is stipulated, I assume it could be altered without harming the module/unit.

I installed new motherboard and powered up.

Everything worked ok except the fan didnt work.

So now I have this question:
