A non-field fan thought that r9000p 2021 display sighs had failed and that cpu had been set up for r7-5800 cards at 3070. According to the fan, local repairers had been contacted for convenience; at first, the business had reported only a few hundred dollars for maintenance, and the price felt to be the right price. The main plate was not moved at the time of the repairs, but the screens were used by peers to replant the core of the card and the visible or the flower screen, following the maintenance programme of the visible card and the visible welding。

The price for fans is changed to a graphic card for 2,000, or a master plate for 2,000. And because the laptop is insured and maintenance records cannot be changed. The official purchaser board is too expensive 3-4k. Searching through the web to find out that we're working with the savers and that there are many successful maintenance cases for the r90000p 2021。

Fault detection:
The laptop was received, the system was activated, the graphic card was seen in the device manager as an exclamation sign, and if it was opened exclusively, it would be a screen, replacing the hard drive and eliminating system-driven software malfunctions。
There are multiple flashback errors when using the graphic card software test, and the normal reasoning is that the core of the card is damaged, but considering that peers have been redecided with the graphic card and the graphic, the pcb base of the card core may be lost or painted. So we start by taking down the core of the graphic card, looking at the core of the pcb plate, with multiple drops and paints。

Communication offers with fans and, when agreed, processing all of the floors and paints of the core pcb card, then replanting the core of the card, welding it back and running the card again. This time, there were errors in the two visible channels, so that it could be established that all previous errors were the drops and falls on the base of the core pcb of the card. Then we'll put in two of the wrong ones and replace them all. Another run-in card test is normal. The loading test is normal。

Summary of failures:
R90000p 2021 3070 card exclamation mark, the original failure should be the core and visible communication failure of the card, either replanted or replaced by the visible memory, which, due to technical equipment and maintenance experience, caused the core pcb plate to drop points or fall paint. Fortunately, the fans have maintained a faith in not giving up, searching the web for what we want to do to save our lives, successfully repairing it without changing the core of the graphic cards and changing the main board, at a cost of less than 1k. It would have been less expensive for a fan to find us in the first place; and if a fan had not found us in the second place, of course, it would have cost a lot of money to change the main board or the graphic card。
