Yes please for the epilepsy warning! Today I learnt that 0 Ohm resistors are a thing. Wouldn't a tiny piece of metal/solder do the same job?

[@JonnyFix]

It would but if there ever was a fault with the screen there'd be no chance it would burn out to protect stuff.

[@Vogtinator]

AFAIK 0 Ohm resistors can be handled more easily by pick-and-place machines than either solder bridges or bent wire.

[@DenfordBerriman]

That fuse looked different to the others. Could it have been one of those questionable components we all hope we don't get from our trusted aliexpress retailers?

[@JonnyFix]

It was the original one HP used

[@daShare]

Why not replace the bad PTC with a correct new one?

[@JonnyFix]

I don't have one and time constraints. I'll order some with next parts order. Highly likely it'll never be an issue though.

Who said disco is dead! 🤔🤣

[@JonnyFix]

I'd celebrate, if I didn't have Saturday night fever!

@@JonnyFix Good one! 🤣
