Monitor screen blur When the weather gets hot, my LCD monitor tends to have a screen blur or even a black screen. What's going on? What should I do? Thank you all, prawns

Just replace a few parts and it is very cheap. If it costs 100 yuan, it will not be used. If it is kept In this case, it is a problem with the screen, which means the screen is not working. But the most expensive thing about LCD monitors is the screen. If you want to replace the screen, it is better to replace it with a new one. Then you can dry it out and squeeze it around the monitor. It may be better.
