Saver screen failure chooses the method of repair, and the playbook is only a few steps away
Recently, a non-field fan contacted us, and the 2020 notebooks he used as the associated saver y7,000p suddenly had a failure to turn on the purple screen。

According to his description, the computer had previously been in normal use and had never been repaired, resulting in a direct “purified” on-board one day and an exclamation sign driven by a graphic card upon entering the system. As the equipment was insured, the official offer was to replace the main board with an offer of nearly $2,000。
Following consultations at the local maintenance shop, the other side expressed the fear of repairing it easily, and the fans were caught in the dilemma of “failed” and “failed”。

01 causes of malfunction
High-performance playbooks such as saviours can easily be blocked if they are often run at high loads and if users have long-term unresolved internal dust。
Continued high temperatures can lead to welding or damage to graphic cards or visible chips, which in turn triggers problems with the screens, dead machines, etc. Especially after two to three years of use, the potential for accumulation of dissipation can easily erupt。
This is y7000p 2020, which turns on the screen, indicating that the failure occurred before the system was loaded, and it can be concluded that it was a hardware problem and that the approximate rate was related to the graphic card module。
02 specialized testing
The diagnosis was carried out using a professional graphic card test procedure, which showed that the b1 channel was wrong. Although the error-reporting hint is concentrated in a single feature, in practice it often means that there is an anomaly in the communication line between the presence and the gpu, not necessarily that the presence itself is damaged。
03 maintenance process
Step one: replanting the graphic card
Thermal insulation is protected from high temperature. The bga backstage was then used to carefully remove the graphic card chip, clean the main plate welding, replant the card and weld it back to the main plate。
The first installed test, the screen disappeared, but the card runs were still low and the test procedure showed that there were still errors reported。

Step two: replacement of malfunctioning
Based on the results of the tests, all faulty visible chips were replaced with brand new items. The re-loading test, the visual memory test passed, the running fractions returned to normal, and the long-term oven and game tests were stable。
04 summary of maintenance
The failure of the y7000p 2020 screen is essentially due to welding caused by the long-term high temperature of the graphic cards and the visible deposits. Specialized bga repairs and visual replacements were eventually completed at a cost of several hundred dollars, saving the fans nearly 2,000 dollars for the switchboard。
Many internet users are often advised to “go to the main board” when they experience similar failures, which are in the hands of technically mature maintenance practitioners, most of which can be addressed through chip-level maintenance, which is cost-effective and maintains original data。

05 carnation note
If your game book is often running at high loads, it is recommended to clean up fan and dispersor cells at least once a year to replace silicon resin and keep it free and clear. This will greatly prolong the useful life of core hardware such as graphic cards and cpus。
In the event of problems such as open screens, dead panels, graphic card exclamation signs, it is not necessary to choose a first-time high-priced switchboard, and a specialized institution with a chip-level maintenance capability can be found for testing, and it is likely that only minor repairs will be required to “restore”。
The choice is right, not only to save money, but also to keep the comrade you know。
