Hi everyone. So I finally got some new parts, and some spare time to rebuild the audio circuit. In the pic the way I did it. The speaker works fine, but when I plug the headphones I can hear only one channel. What's the matter? Also, at the moment I have no overheating problems, but I did only a 10 ...

you have a headphone socket and that's not shown in the diagram, especially as the USB sound card was overheating when headphones were plugged in..... how have you wired the headphones? do you have a volume wheel, if so how is that wired? how is the ground for the audio wired (complete circuit)? Wh...

Hi everyone! I finished my first build two weeks ago, and I am very happy with the result and the overall experience (never used a dremel or a solder before January 8-) ). I also made a video to celebrate it (with thanks to the people who helped me, like RodoCop, you can see it here, sorry it is in ...

Thanks Rodocop, and great advice! I already started to ask in the forum for modding the unknown screen's board, hope that someone will find a solution so I'll surely start working on my second build, one day 8-) Meanwhile: DHL texted me to say that the Xianjie screen will be delivered at my home on ...

Hi, I got this board form BW. Seems some sort of remix of the one you were discussing about in this topic. One problem is that the number of one of the chips is scarcely visible. It is the one in yellow in the photo; in the detail photo the number seems to be MK 25D46BTIO 1720, but I'm not sure (the...

Hi everyone, having unsuccessfully tried to mod an Amazon screen (though the last word has to be written yet: https://sudomod.com/forum/viewtopic.php?f=44&t=4929&sid=9eb93d1917ae7b762f55fd5d4c2cd23c ), I bought a XIANJIE 5v-ready screen from Alibaba, which is going to be delivered at my home next th...

Hi don't you believe that the 6 pins IC in the red circle could be the power IC? Like that: https://www.sudomod.com/forum/viewtopic.php?f=44&t=3892#p44008 or that : http://lcd-television-repair.com/newsletter/LCD_&_LED_TV_Monitor_6_Pins_SMD_Power_IC.html bwscreen.jpg I'll sure give a try as soon as...

Hi everyone, I'm here just to thank all the people who helped me trying to make this screen work. Unfortunately, it is still not working. I'll get another screen soon, probably the Shenzen one. And if one day someone will ever get this screen working, then I'll start to build my second Game Boy Zero...

Hi joey, and many, many thanks for your help. I Just checked the numbers on the two chips, but I found no XL1509, I have: the one on the right: RZC2013S the one ont he left: T25S40 I find these specifications on the Internet: RZC2013S: http://img009.hc360.cn/m8/M07/AA/BB/wKhQpVYt9feENd_8AAAAAHR4jTI8...

Check theses guys here: https://imgur.com/a/mT4gB You are looking for the IC 1509, the DC to DC converter is the one you are looking for. The datasheet for it is: www.xlsemi.com/datasheet/XL1509 datasheet.pdf Just check with some loupe or magnifier glass to check the pinout. Counting from the smal ...
