Phone repair - Anything else I can try?
Discussion
I'm trying to revive an old phone, HTC one M8. I'd previously replaced the battery but eventually it stopped charging and went dead again.
So I opened it up again a few days ago and put a new battery and charge port in. Still dead as a dodo, no lights, vibration or screen display.
Anything else I can try or just bin it?
Cheers,
Dunc.

If there's juice coming out the battery (measure with a volt meter), then typically if it's totally dead it's the main board in the phone which you cannot get spares for.
Depending on the phone you can check the connections from the batter get to the main board ok - typically there's a wire that goes off to a small connector on the main board. Note that you need a multimeter with very sharp pointed probes for mobile phones! And if you slip with the probes you have every chance of shorting stuff out or scratching the tracks.
If it showed any signs of life then you might be able to poke about and determine one of the ancillary circuit boards at fault and get a replacement for a pound of two on aliexpress and replace.
As noted above the cove of old refurbs is low, so it's not worth spending much on this. I normally draw the line at £40 when noodling with old phones.
