本人的IC-7300因为一些原因磕碰到了屏幕，现在屏幕上有很明显的磨损。在闲鱼上找人维修被要价400并表示只能更换整个液晶模块。想问问各位大佬有没有这种液晶屏幕的型号信息，我自己网购自己更换，或者有没有更加经济实惠的维修方式推荐，如果有大佬愿意低价帮我维修的话我也很乐意 [upl-image-preview uuid=38edd3f1-4967-4f72-b944-8bb83f3a81d2 url=https://storage.hamcq.cn/2025-05-04/1746369948-651661-202505042245151.jpg alt={TEXT?}] [upl-image-preview uuid=7c6662ee-05ce-4c0d-b8ff-2d9eafe3918b url=https://storage.hamcq.cn/2025-05-04/1746369975-920885-df1eace02bbfd804f016a9b31dc321b.jpg alt={TEXT?}]

最后我因为不满意之前买的屏幕极低的亮度和极窄的可视角度，重新换了一块屏幕，这个屏幕的主控IC和原装屏不一样，不是ST7282，但是换上之后可以正常使用，亮度和可视角度都比原来好得多。希望我的经历可以给大家一些帮助： 1.屏幕只要是标准40pin的4.3寸TFT液晶屏(分辨率460*272，针脚定义楼上有)，IC7300就能用 2.别买海鲜市场上的ic7300拆机屏和定制屏，很贵，不值 3.可以自己买裸屏+电阻触摸膜，手动组装一下，不麻烦

之前鱼上有其他爱好者自己做的7300屏幕，好像100元左右

@"BG6HFD"#p63840 请问有没有链接或者关键词呢？我在咸鱼上好像没有搜索到

@"VR2ZNB"#p63848 搜用户anyBaker，之前的屏幕是卖完了，目前在收集需求

这两款应该都可以 [upl-image-preview uuid=4507a978-db47-482d-ab26-32242181247c url=https://storage.hamcq.cn/2025-05-08/1746688885-833302-img-1871.jpg alt={TEXT?}]

出售一块9700的原装屏幕，闲鱼直接搜就行

你看下屏幕尺寸大小，像素大小多少，还有硬件接口是什么的。搞清楚这些，基本上自己就可以修了

我之前发过DX10自制屏幕的教程，可以看我之前的帖子参考下，主要是接口定义那块

之前查过，这是一款标准的液晶屏，看到国外网友买的规格查一查后会发现很多深圳的厂子生产，淘宝也有，只要注意一下pinout就可以知道都是一样的。

IC7300 screen repair

VR2ZNB

The screen of my IC-7300 has been damaged due to some reasons, and there is now a very noticeable scratch on the screen. When I tried to find someone on Xianyu to repair it, they quoted 400 yuan and said that they could only replace the entire LCD module. I was wondering if anyone here knows of any specific models with this type of LCD screen. Alternatively, are there more affordable repair options that you can recommend? If anyone is willing to help me repair it at a lower price, I would be very grateful.

BG6HFD

Previously, some enthusiasts had installed screens that cost around 7300 yuan (approximately $100).

VR2ZNB

BG6HFD Are there any links or keywords you can provide? I haven't been able to find anything on Xiaoyao (Pinduoduo).

BG6HFD

Official screens are indeed more expensive.

BG6HFD

VR2ZNB Searching for users named anyBaker; previous screen sales are complete, currently collecting demand.

BG8AOI

Both of these should work.

VR2ZNB

BG8AOI Thank you for the recommendation. The second store said that they no longer have this main control IC in stock and will not be restocking it. The first store was unable to identify what specific IC it was.

BG5BQB

Selling an original 9700 screen. Search for "9700" on Xianyu directly.

BG4KHT

Check the screen size and resolution, as well as the type of hardware interface. Once you understand these details, you should be able to fix it yourself.

BG6HFD

I previously posted a tutorial on creating DX10 custom displays, which you can refer to in my previous posts. The main focus is on the interface definition.

I checked this previously, and it's a standard LCD screen. After checking the specifications of similar screens purchased by foreign users, you will find that many factories in Shenzhen produce them, and they are also available on Taobao. As long as you pay attention to the pinout, you can see that they are all the same.

VR2ZNB

BA7JKX Thank you for the information. However, I noticed that the original ST7282 controller used in the 7300 screen is no longer available, and when I searched for this controller on an e-commerce platform, I found that either it was out of stock or lacked touchscreen functionality. I would like to ask if different controllers can be compatible with each other. For example, are ST7282 and ST7262 screens compatible? These screens have no differences in other parameters, and both are standard 40-pin models, but the controller IC is different.

VR2ZNB

A seller on Xianyu who offers customized 7300 screens stated that the pin definitions for the 7300 screen and standard screens are different.

VR2ZNB The touchscreen can be attached separately. Check if the ICs have compatible interfaces, especially for the touchscreen part. If they are the same, it's likely to work. When replacing a screen, also check if the cable positions match.

VR2ZNB

I haven't actually tried it yet, but my understanding is that I should follow the pinout and protocol specifications. The master controller might be compatible (and even if it's the same master controller, there could be differences in configuration).

BI4UMB

Please contact them to inquire about availability.

VR2ZNB

BI4UMB I've contacted them, and they have stock available in August. It's been a very long wait.

I saw a repair video on YouTube mentioning the Raystar RFE430V-AZH-DNS module, and after checking the datasheet, I found that it's compatible with both AliExpress and Taobao. However, I haven't purchased one yet. I hope the original poster can try it out.

Then I noticed that the pinout was:

Then I looked at one of the products sold on Taobao:

The item I favorited on my Taobao collection is shown below; it should be a resistive screen, but I'm not sure which brightness setting to choose.

I feel the same way. (And I have no vested interest in this store, so I won't include a link. You can just search for this store directly.)
