What to do after rebuilding VGA chip pins?

Laptops utilizing discrete VGA chips typically use one time to fail. And the defective laptop computer accounts for greater than 80% of the VGA chip. Errors associated to the VGA chip akin to not displaying up, displaying up however having stripes, or booting to home windows however the display screen continues to be black. Mild show can re-steam the chip, the machine is up, heavier, you need to change the brand new VGA chip.

The reason for the dying of the VGA chip is generally attributable to overheating, the warmth dissipation isn’t good, inflicting the chip to die. The VGA chip after changing or re-steaming the legs will run hotter than the unique, and once we reheat, the VGA chip won’t be as excessive as the unique (as a result of the lead ball is sinking) making the warmth dissipation not good. The chip will die once more. So what do we have to do after rebuilding the VGA chip pins? Please observe the next steps.

1. Add a bit of skinny copper heatsink on the again of the VGA chip, the aim is to assist the VGA chip contact the FAN’s copper heatsink higher. The brothers lower a small piece of copper with a bit of glass of the VGA chip, about 0.8 – 1 mm thick and positioned on the again of the VGA chip.

2. Use good thermal paste akin to Arctic Cooling MX-3, MX-4, Noctua NT-H1, CFIII or  Xigmatek Freezing Level. And proceed to use a skinny layer on CPU chip, North chip, VGA chip. VGA chip, you apply it on the glass -> put a bit of copper on -> apply one other skinny layer on the copper piece.

3. Cleansing the heatsink FAN meeting: Together with eradicating the outdated thermal paste, cleansing the fan blades, utilizing RP7 to spray on the fan’s rotating shaft, and on the identical time making use of oil to make the fan rotate higher.

4. Re-wire the fan, usually the fan makes use of 3 wires: yellow to regulate the velocity, pink to energy the fan, black to hook up with the mass. You proceed to chop off the yellow and pink wires, leaving solely the black wire within the jack. Then use a Vol meter to search out the 5V voltage for USB. Lastly proceed to fish the pink wire of the fan to the purpose of 5V for USB, and the yellow wire is left unused. The aim of utilizing the 5V USB energy provide for the fan, when beginning up, the fan will rotate repeatedly with out turning on and off when the CPU temperature will increase because it was initially. It will assist cool the chips very effectively.

Above are the 4 steps that you must do when changing the video chip, re-steaming the chip to assist the chip life longer. As well as, you should utilize the above strategies to repair laptop computer issues that mechanically flip off attributable to overheating. Want success.
