Hello Recent I broke the LCD track and shows nothing on the screen. I've been looking for a screen on AliExpress, but I have a lot of doubts since the original screen comes a separate controller, and those selling on AliExpress don't have it. Anyone recommends a screen to replace it please?

the CD4050 is a voltage-converter not an lcd-controller.

Its a ST7735S compatible here was the same problem Beitrag "AVR TransistorTester China DIY Kit - Display zeigt nichts an" most display boards on aliexpress are only 3.3V compatible. the second problem is is the pin assignment compatible.
or you buy the original https://3v3.com.ua/product_8282.html and replace the display only. i think this is critical. the easier way ist to measure the pin assignments and buy a 5V-compatible model with the same pin assignment or something like that.
I've found the LCD on aliexpress US $3.20 | Puerto serial SPI TFT de 1,8 pulgadas, pantalla LCD a color, 18PIN, 128x160, ST7735S, espaciado de pines, 0,8 MM, Z180SN007, para probador de Transistor GM328A https://a.aliexpress.com/_mL9kGPP Unfortunately, the price+shipping cost the same than buy a new one US $6.74 5%OFF | Probador multifuncional de Transistor GM328, capacitancia de diodo, medidor de frecuencia de voltaje ESR PWM, generador de señal de onda cuadrada https://a.aliexpress.com/_mOGt8t7 So I bought a new one and I will save the remaining pieces.
