Hardware Jasper with parasitted HDMI

[giovany86]

Hello everyone, i'm having a weird problem on a Jasper 360.

With the AV Port, absolutely no problem BUT with the HDMI...it's weird.

I tested it with 10 different HDMI cables, on 4 different TV, on some TV there is just "No Signal" and on others, it's clear, the image is here BUT with some stranges parasites on the background waves.

I cleaned the entire motherboard, changed thermal paste, even tried a Falcon PSU instead of it's original but nothing worked.

Anyone have an idea about what can cause this weird issue / how to solve it?

I have a dead jasper motherboard laying around, should i try to replace the chip who manage the HDMI signal with the one from the dead jasper (i have a small hot air work station)?

Thanks for your time and have a good day / night / noon / week-end

If the HANA chip is busted or has a cold solder joint then the unit should spew out a E error on screen and RROD.
It could very well be that your HDMI port is just fucked.

I saw a video on youtube where a trinity 360 has exactly the same problem as mine, the guy fixed it by replacing the Hana chip, if i do that with the one (working) from the dead jasper mobo should it work ? I don't think it's the hdmi port the problem because it "work" on some others tv (juste with some parasites likes with badly overclocked graphic cards), it's a bit like that but on the home dash (on the background waves, i didn't tried with games because i didn't have one at the moment i bought it) :

There's nothing stopping you from transplanting them.
You can attempt it.

i've already transplanted parts from a dead psp mobo to another psp mobo and it worked x)

Just out of curiosity, what rework station you got?

I have a similar issue to the one your having. If using Component fixes it I’m happy for how, but did you ever fix the HDMI output? I have the same problem but it’s green dots and sometimes lines.
