How to Fix Garbage Display Video Card

How to Fix Garbage Display Video Card 

Base in my Experienced i did revive my hign end video card 9600GT which i purchased 5kphp  (5,000) pesos but after 1 year and my warranty broke, sad it goes my nightmare cames my card got black out , so i search for remedy and tones of time i spend to how to fix this blackout display card .. sorry but it a same issue with this topic i wrote a garbage display same problem and same method to fix it..


    ok let start.. i try and tested this two method.

*First Method  Repair VGA card by re-flowing solder on the board with the help of oven

First Method  Repair VGA card by re-flowing solder on the board with the help of oven

Repair VGA card by re-flowing solder on the board

Step 1 — Faulty VGA card due to fractured or cold / dry solder joint 
Remove the video card (if it's installed in the system)

Step 2 — CHECK YOUR WARRANTY 
If the card is still under warranty, get it repaired by the manufacturer. Otherwise, continue with this guide.

Step 3 — You will need: 
precision screwdriver for the fan and anything else screwed onto gfx card
Aluminium foil to cover heat sensitive components
Some thermal paste to extend reflow life (personal favourite - ARCTIC MX4)
Paper towel to rub any excess of old heatsink compound from the components
LIQUID FLUX to help solder cure into stronger bond when dried / cooled [this needs a step listing where and how it is applied]

4 - Preheat the oven to 385F (195C).
If you've already finished this guide once and are baking again, increase the temperature slightly -- 395F (200C) or 400F (205C).
Solder melts at different temperatures depending on the type, so if you're squeamish, you might start at 375.

5 - While the oven is pre-heating:
Remove the screws or clips holding your fan and heatsink and any ductwork from the video card.
Gently take the fan/heatsink off
remove any old heatsink compound from the chips (paper towel)
Place the screws in a safe place

6 — melting point 
be patient
you want to heat the GPU SLOWLY.
5 -10 mins at 200-220C
my experience: ps3 - 6min, xbox - 4-6 min, desktop boards -12 min , laptop baords - 8-12 min, GFX - 8-15min
use this as help only - not a golden rule , apply some changes when feel like you need to and find best way for yourself, only experience and knowing your equipment can take you to 100% succes rate.

7 - Once the oven is at required temperature set a timer for 8-12 minutes.
Place the baking sheet or dish in the middle of the oven.
Do not leave the oven unattended for any reason!

Step 8 - when ready open the oven door - let fumes out , keep opening and closing like 5 - 10 times. this equalizes temaprure difference
hold your tray firmly. carefully try not to touch anything or make sudden moves as components can be dislodged while the solder is still soft.
You may notice a smell from the molten solder/flux.
Leave it on the side to cool whatever time is needed to do so - let it do by itself. using fans might result in weaker joints or unsuccessfull reflow

Step 9 — Make sure the card has cooled enough to touch it before continuing.

You have 2 options:

1. Test the card quickly without reinstalling the fan/heatsink.
2. Reinstall the fan/heatsink, then test the card.
Most people will want to test the card to see if it powers on and passes the POST.
If you are trying it without the heatsink/fan, DO NOT run it for longer than 30 seconds.
If the card still doesn't work after baking, you may repeat the process and might need to increase its time

10 — Installing the heat sink 
Apply some thermal grease (thermal compound etc) onto the GPU, RAM, and any other place that is required.
Use only a small amount of thermal paste and spread evenly over the surface using a piece of cardboard, a credit card
If re using thermal tape or pads that were saved during the disassembly, place these back in their original position
REMEMBER - heatsink paste is there to make space between chip and heatsink airtight so most of the heat finds its way - away

11 - Place the heat-sink over the GPU carefully, lining up any screws or clips.
Insert and tighten all the screws carefully! They are usually quite small, and the PCB may be damaged if the screws are over tightened.
Tighten the screws in an alternating pattern. E.G. Top left, Bottom right, Top right, Bottom left. With more than 4 screws, use a "Star" pattern when tightening the screws ensuring all screws are evenly tightened
if noticed any dust - make sure that has been cleaned too

12 — Final checks 

Second Method Repair VGA card by re-flowing solder on the board with the help of Hot Air tools

it a same procedure and my favorite method due for easy and you can control the heat of the tools when applying on the card ..

1. just open and apply the heat on the memory and the Gpu .just hit and run method

Check that the fan was reconnected (if there is one).
Check that the fan spins when the PC is powered up.
Make sure the GPU works when loading up in Windows,
Install  program to get is GPU-Z. it can display the GPU temperature on supported cards.
