A matchstick! :grin:
I would never have thought of that :grinning:
Well 2 boxes ain't so bad.
What's wrong with the S905X? I am an expert at bricking. :grin:
My other s905x box has no processor πŸ˜‚ Can you help me put it back?πŸ˜‚
I was trying to take off the heatsink, it was glued to the processor, I tried taking it off and the heatsink along with the processor came offπŸ˜‚πŸ˜‚
Damn, that's really bad. :grimacing:
I wish we could sell it for parts, but... :))

Well now others will know that they will have to be extremely careful when playing around with the heatsinks on these things. I usually just slide a thin knife between the processor and heatsink, never applied heat to soften the glue. Next time I will try using a razor and a blow dryer.

Thanks for your experiments. :relaxed:
Yeah, I'm never touching a cpu again, they are too sensitive ':)

:grinning: I have an A95X 1g/8g that was giving the "no hdmi signal" issue. This happened after I removed the heatsink. I remember applying pressure to the processor got it working.
One night, out of sheer frustration, I slammed it down on a table so hard, it refused to come back on.
Never thought about keeping constant pressure on the processor though. :grimacing:

This sounds like the processor is not soldered properly and I wonder if a couple seconds in an oven would help. :thinking:
Not a couple second, more than that. But you have to heat the oven slowly and gradually. Check for reflow oven in google. I once tryed with a amlogic tablet and a oven toaster. It fixed my video output problem that likely had broken soldering point but burn the microphone diagrphram. It was ok with me since I prefered the hdmi output over the mic. But you want to do it with a toaster oven you wont use anymore for cooking because of the chemical released. The best it's still to use a hot air soldering station and only heat the needed part and protect the other parts. A lot of video tutorial on youtube that explain how to reflow a cpu on a laptop mobo (same process than for a tv box).

Released chemicals?
Thanks for that info. I will keep that in mind.
Problem is the toaster oven costs more than the box and is a long way from being discarded. :grin:

What if the box is placed in sealed zip lock bag?

You can give a try with a heat gun (used to stripped paint - maube your neighbor has one ). You can place an aluminium over your board with a hole exactly where you want to heat.

*** it is also important to put some flux over your chipset***
