Re: Dead Rx480
Hello,
I replaced the IR3353 chips and the two blown fuses
All grounds were gone.
I plugged it in and all the fuses blew and x3 IR chips went to ground.
I replaced the 3 IR chips and blown fuses, no grounds again.
plugged it in again and the IR chips were arcing, didn't blow any fuses.
Any ides, ill link a video i took.
Even the spot that has no IR chip is Arcing.
and yes the bottom cap is just temp..

Re: Dead Rx480
Hello,
Its a Sapphire Nitro RX480 8Gig,
Its been sitting in the cupboard for a couple of years,
It died and was one month out of warranty, they wouldn't cover it.
Ali is good but the postage is sooo sloow, the capacitors i ordered are arriving end of February.Leave a comment:

Re: Dead Rx480
I removed four IR chips and tested for ground after each one, the ground disappeared after removing the fourth chip.
Then i noticed a tiny resistor or fuse had come off next to one, ill post a pic, if anyone can let me know what it is that would be great.
Thanks for your reply's so far....Leave a comment:

Re: Dead Rx480
Hello,
I have ordered a hot air soldering iron and a hot bed (thanks foshland)
Just not sure if i can use these chips and caps
the cap is a 5KW20 270 16V and the IR is 3553M C610P 3RR3
AliExpress said to use this IR IR3553M IR3553MPBF IR3553MTRPBF PQFN-25 New Original Genuine IC Chip
I found this Cap 16V270UF 8x8
Will these be ok to use.
Thanks...Leave a comment:

Dead Rx480
I have an old RX480 i trying to get going,
It has a ground on the two main fuses.
Causing this i believe it is the IR 3553M C610P 3RR3 chip
Watching this video helped, its the same fault [url]https://youtu.be/R8zXFcxyWc0[/url]
I also need a 5KW20 270 16V capacitor
I am unable to locate these to buy, and have no idea how to remove the IR3553M chip. i just cant seem to melt any solder on the board, tried x3 irons
I attached some picture of required parts.
Thankshttps://I have an old RX480 i trying...wo main fuses.... -
