April 23, 2010 at 02:41Cleaning the VGA connector on the graphics card
- Tutorial
Greetings!
Yesterday I had an unpleasant situation on an old computer with the good old Vidyakh GeForce MX440 - during operation, the screen suddenly began to blink in yellow. Later it was found out that the fault was the poor contact of the connector. Attempts to clean it with a needle were unsuccessful. It was decided to disassemble.
Traffic!
So, what do we have:
0. A video card with a flapping connector
1. A soldering iron (40W is great)
2. A thin screwdriver, tweezers
3. Alcohol, cotton, needle
4. More or less straight arms.
The first thing we do is twist the bolts that secure the metal bar to the connectors and remove this same bar. Next, remove the metal crown from the connector.
To remove the cover from the connector, you need to remove the metal fasteners from the board into which the screws are screwed. We heat the solder and shift the fasteners towards the GPU. Now we can bend the fasteners slightly so that it is convenient to pick it up. We take tweezers and carefully remove the fasteners, while heating the solder on the other hand with a soldering iron. In the same way we remove the second fixture. Most likely there will be solder in the holes. It must be removed (in any way known to you; I turned the board over and heated it from below with a soldering iron - the holes there are quite large, the solder flowed out and remained in the sting) so that you can later insert the fasteners into place.
Now we are looking for the latch below, push it, and slide the lid towards ourselves - it can be easily removed. After such simple gestures, we can see the insides of the connector.
Now we think about the possible causes of interference. In fact, they could arise either as a result of oxidation of the contacts, or due to the loose fit of the legs to the petals.
We take a needle, and carefully clean each petal from the inside. After we take the alcohol, pour it into some small container (I had the cap from the old vial with alcohol) and dip all the petals into it. You can, in principle, even without a lid, thoroughly moisten them in alcohol with cotton wool, for example, but it was more convenient for me to leave it with a lid for a while to “poke off”. We wait about fifteen minutes, remove the tank with alcohol and blow out the connector to remove drops inside the petals.
These actions would be quite enough, but when cleaning with a needle, we could unbend the petals, and just to make sure we squeeze each petal with a tool convenient for us (I took the “ducks”, but the tweezers are also suitable).
Now the connector can be assembled. First of all, the cover - we put it on carefully so as not to bend the contacts. After we take the fasteners, insert them into place, align, clamp with bolts and seal.
This is what I got after sealing. We dress the crown, attach the bar on top and fasten it with bolts. That's all, the connector is cleaned, the board is inserted - we rejoice in a clean and beautiful picture without interference on the screen!
PS: Most likely, the warranty on your video card will expire after the above actions, but if you do everything carefully, then no one will notice anything, but you should not forget that it is not good to deceive.
