A fellow worker came to me very desperate because his Motherboard (MB) BIOSTAR H61MGV Ver: 7.0 was out of order. He told me this MB was just new, he had bought it only some months ago, and it had no video-out, and a tech had checked it and the final conclusion of this tech was: you have to buy a new Motherboard.




In my country this technology is very expensive, therefore I told him let’s have a look.    biostar-motherboard-repair

First thing done was to check on all the output voltages of the Switch Mode Power Supply and they were ok, at simple sight you could see there were no bulged e-caps in the Mobo. Suddenly an idea came into my mind: to extract the PCI Express Graphic Card and connect the Monitor into the VGA connector built-in the MB. fix-motherboard

This time there was video-out in the Display connected to this port (sorry, I forgot to take a picture). My fellow-worker saw what I did and was very happy that there was display. This confirmed the motherboard was working and now I had to service the Graphic Card (GIGABYTE GV-N210D3-1GI Rev: 3.0) and after that, thermal compound was used. The golden contacts were cleaned with a pencil eraser and a brush.

When the card was inserted into the PCI Express slot and the PC was switched on, it worked perfectly fine. graphic-and-motherboard-repair

Conclusion: this was a simple repair in my humble opinion, but the main keys are the patient and dedication that the repair person has in the wish to solve a situation. If this duty would not be dedicated to this Mobo, it would be now in the dump and the owner would have to spend a lot of money buying another one.

    I'm glad Humberto you could 'repair' the customer's Graphic card.
    Most of my Graphic cards suddenly stop working by overheated bga GPU chips and were not repairable anymore. My last expensive AGP card with HDMi out signal died the same way. Hotfixing probably won't fix an already overheated GPU either. Even if I had a PC controlled hotfixing Machine.

      Wow Albert! It's a pity when you lose a Graphic Card, because most of them are expensive.

    Greetings, Humberto. I wonder wich type of technician had seen this equipment before and was not able to do such an obvious repair like this. Saludos.

      Thanks Gerald. I really wondered myself: why the other tech did not check carefully this MB? It was not out of order.

    For the novice, the use of a 'green' eraser is fine to a point, you just need to bear in mind that you are not removing ink from paper, and a little light use is all that is needed. We in the 1970's used this practice all the time but the company found that some engineers were too vicious and removing the gold (it is only microns thick).
    We were issued with Rouge and to clean off with IPA. But this left a film and gave even more problems. So in the field we reverted to the light use of the proverbial 'green' eraser.
    If you do go through the gold and you see copper then a coating of Electrolube Contact Treatment Grease 2GAX will prevent oxidation and lasts quite a long time. It also fixes 'Pots' (Variable resistors).

      Thanks a lot for your advice Dave, I really recognize and I'm concious about the trouble with the thin layer of gold. In my country is impossible to get the Grease 2GAX.
