Hello guys! I'm working on a RX470 4GB from PCYes (Brazilian brand), it basically is a reference card re-branded, even removing the brand adhesive from the fan revealed a Radeon logo adhesive. The code from the PCB returns as RX480 reference card from AMD Radeon (109-D00947-00_02). It was...

Hello For what i know 6 beeps on a HP system can be a video issue or a faulty important component on your mobo, depends on bios model, but i would assume that yours is related to video issues. So, if i understand correctly, with the 650ti plugged it boot on windows and works fine but can't go to...

Hello guys! I have a GTX Titan X from a client to repair. The fan and fins got completely blocked by dirt, and as the Titan have a blower style cooler, it killed the card. I started by cleaning everything, doing a rebbaling on the chip and a reflow on VRM controllers, it came back to life with...

Hello tech maniacs! I was wondering if any GPU/Hardware Guru can help this mere mortal here. :respect: Normally when a graphics card comes to me it's a bad BGA soldering or something "basic". Last one was a GTX780Ti that had a real hard OC: broken BGA on the processor, on processor's VRM...

No, actually in six GPU repairing that i've done until today, just this one i had to work on this part of the card, and i prefer to not take all of these out :eek:. Well, i was not disagreeing with you or Zach_01. I guess that i could made it clearer, my bad. In my answer i said "But actually...

I will take out some capacitors around that looks similar and take some measures to see if it follows some pattern. I dunno if even a great oscilloscope can measure the signals around there, but i will give a shot. I never designed too many circuits by myself, but participate in some. Always...

Got many physical service manuals of older things, many .pdf too, but for others things it's pretty easy for getting a datasheet or service manual. But have being working on GPUs and PC parts just recently and found so few peoples actually repairing this things. Not that it really shows the...

Actually i upgraded my pc from a 9600GT to a GTX550Ti, then a HD7870 and now i have that HD7950. Apart from my very first ATI X1600, i had to repair all of those (but was actually fun to do it =D). I imagine that not everyone wants to run the heaviest game on highest settings (like me), just...

Yeah, that was one of my points on the answer to Khonjel, i understand that in some country it's cheaper to do this. But let's compare the differences between countries, you live in a country where average monthly income is about 1000~2000BRL, just in electricity bill you pay 300~500BRL, a...

I am used to deal with components smaller than those, so replacing should be the easier part of the repairing. The size should be about the same size to fit the circuit space. But about the shade of the color, it just depend about the material used by the manufacturer, it don't actually...

Yeah, it's a shame, they only support their newer and more expensive cards (i guess they don't provide repair services for those too). On AMD cards i don't even found on their site information and specs about a HD7870 and a 7950 that i repaired a few days ago. For some countries i understand...

Hi folks! So, digging deeper and deeper on PC repairing i encountered some barriers. Got yesterday a GTX560 with two broken capacitors in that messy circuit just under the chip, and troubleshooting this area of the board without a schematic can go from something like "i will break my head, but...

Good to know that someone already did this and worked, thanks Ferrum. I'm going to try the cheapest of this Ali's chips. My current pc is a Core2 Duo w/ 4GB DDR2 and a 9600GT. I ordered a Quad-core Xeon from Ali, so this Radeon would be a huge upgrade for the setup. (I'm saving money to my...

Hi guys, i bought a Radeon HD5870 at extreme low price this weekend ($2) with the idea to fix and maybe use it. The old owner said that "it just stop giving video, but works normally" :kookoo: yeah i know, huge trap :banghead: I just give it a quick look, but it have a lots of bad soldering...
