My MX02 suddenly lost it's HDMI output...

Is there any way to force a firmware download to the unit in the off chance that's it?

The chip right next to HDMI output is slightly warmer than I'd expect...

I suspect it that chip, but in the off chance I could re-download the firmware to the unit, I'd like to try....

Thank You....

Jan

Hello Matrox....

On the MX02 Printed Circuit Board, there is a Surface Mount chip that drives the HDMI output.....
Mine has DIED.... It's warmer than it should be.....

I'd like to buy one from you if possible... I have access to a surface mount repair system.... for the repair...

If you don't have one to sell, could you kindly tell me What model number & speed if needed, the chip is, so that I can contact the manufacturer for one...



Thank You...

The chip for A19, the HDMI output driver on an MX02 system is:
AD9889BBCPZ-165

Now just looking for a Pro that can do Pre-Heat and Hot Air PCB work.... to replace this chip....

Does Matrox want to give any cautions on this..????
Is the pad underneath chiip soldered to PCB, or not?, Etc ???

Had this been plated through holes, I'd have had it done by now.... But though I did component level Repair at the Network I worked at, I never got into Surface mount PCB repair work.....

That's why I'm looking for a Pro wit Pre-Heat and Hot Air PCP work!!!

Well here's an update on the MX02's here....
I had one unit with bad HDMI Output... Have Replacement Chip... But can't find anyone with hot air system to replace it reasonably...
Matrox want's $600 for out of warranty exchange... 2.5 times price of chip replacement...

But! I have a second unit! So I'm fine!

Then in May of 2020, we had a lightning strike 1/4 mile away, and everyone on Cable Internet got zapped real good... We lost HDMI In and Out on our spare MX02, HDMI DA, HDMI Switcher, TV connected to HDMI Output, and a 24 port gigabit router....

All Neighbors around me also suffered big losses...

After adding lightning protection (Gas Tube Surge Suppressors) on entire neighborhood's Cable feeds at each house...

I got around to looking at next bad MX02... Same problem with HDMI Output... Chip needing hot air system I don't have... (Used to do Component level Repair for TV Network in Chicago, have solder station, but I never got into Hot Air Surface Mount repair)...
HDMI INPUT CHIP is only licensed to be bought by HDMI Consortium Members!!!
Wow, That's Exciting!!

So I go trolling on Ebay.... Used TV Equipment broker has MX02 but no Power Supply or Computer Connection, so he can't test it...

We agree on a $15 charge plus shipping, with me allowed to test it for all active outputs....

I got it, Updated Firmware, and tested... 100$ operational!!

So I'm back up for $25....

and then I get contacted by another.... and he gives me one!!!

That grin on my face means everything!
