The fuse on my PS1 easily blows when the console is bumped just neded to know if it was a common issue or if what something dire. We have already replaced it with another just wondering if its a huge issue that was with all of them or is rare.
I guess it was a fuse inside your PS1? Was it only the one, or did you change it and it occurred again?The fuse on my PS1 easily blows when the console is bumped just neded to know if it was a common issue or if what something dire.

i changed it then it occured again because i accidently bumped the cord but ive made sure to power it off now before even touching it other than power such as disc and so far it hasnt blown the new fuse. and we are using the right fuses. it happened when i got it from my dad i powered it on it started turned it offthen sat it in a corner then the next time i powered it on it was out we switched it i accidently bumped the console slightly then it blew the fuse before the one it has now. And when i had it open i saw nothing lose checked capacitors resistors and even the board while it was open. still worried on if i bump it sorry its so long alot of history on just a fuse slotI guess it was a fuse inside your PS1?

If it was only the one and you've since changed it and the new one didn't blow, it might have degraded due to age, but if it is a recurring problem then there's likely something wrong with your PS1. In either case, you should probably inspect the traces and components ideally with a multimeter and check for shorts just to be sure. I am not familiar enough with the PS1 to know whether there are any typical failures to look for, however
the powercord might be causing a spike if damaged which will likely cause your console fuse to burn. other problem that was the old hw mod for the laser, the first mod i knew of for the PSX done quick jobs around where i lived back then made a the phase angle slightly wrong which could also blow a fuse when plugged for a long period.i changed it then it occured again because i accidently bumped the cord but ive made sure to power it off now before even touching it other than power such as disc and so far it hasnt blown the new fuse. and we are using the right fuses. it happened when i got it from my dad i powered it on it started turned it offthen sat it in a corner then the next time i powered it on it was out we switched it i accidently bumped the console slightly then it blew the fuse before the one it has now.

Although your answers are very often excellent, this time he/she was talking about a PS1 and not a PSPPower cables, especially barrel connectors, can fail somewhat short or send things up the wrong way -- might want to poke a meter into the end to see what it says, pressure the strain relief and see what it says then (use pins to gain access if you have to). Do also check the bottom of the charger hole for any tin foil. For the meantime all PSPs should support USB charging, though you might have to go into the settings to sort it.
As above sometimes it can be a loose screw, sometimes it can be something shorting out against a case, other times it can be a short on the board that the pressing of a button or turning it upside down will cause to activate a short. I don't think this will be something coming loose and something else dumping current (see why you are told not to remove inductors in operation) but that is a further option for some things.
I have not heard of this happening on a PSP but at the same time I am not really in the weeds of PSP component level repair. Have seen it happen on any other number of boards over the years as one of the more annoying but repairable options in such things.
Depending upon where the fuse is then you might be able to use that to narrow things down (if it is before the fuse that is one thing, if it is after the fuse that is another). Otherwise bumping is OK but tends to trouble everything. Might want to instead make a minimal viable booting thing and then apply force to various points on the board to find the most likely candidate. From there visual inspection and current measurements as you chip off sections of track to find whatever bridge, via or part of a layer is causing you fun.
There is such a thing as a resettable fuse as well that might help in diagnostics/narrowing down location rather than soldering new ones every 5 minutes but they are expensive and will likely be a special order.
Ah yes. Must have had PSP on the brain.Although your answers are very often excellent, this time he/she was talking about a PS1 and not a PSP
