In the end I did not change it, I disassembled it to know the model to buy. I cleaned the contacts and when I put it back together it started to work properly. But I had found this page on aliexpress. es.aliexpress.com/item/1005001678877931.html?gatewayAdapt=glo2esp&spm=a2g0o.ppclist.product.2.7290EAN1EAN1FN&_t=pvid:3437b9d9-5f30-4f9c-8a52-fca41dc87789&afTraceInfo=1005001678877931__-911__pcBridgePPC__dKbFdLr__1650401374855
@@fantasticofficecollection7742 what was wrong with it that made you take it apart and clean it? Mine suddenly has a whole bunch of black pixels out of nowhere. Assuming the DMD chip crapped out.
@@grumpyssandbox8363 This projector started out with a few gray pixels, then went on to have the entire screen mottled gray. Disassemble the DMD to make a note of the model and purchase one. but when remounting the old DMD, it started to work. I guess the problem might be dirt on the DMD contact. or a bad contact. Another projector that I disassembled had a dust problem on the lenses, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-z38lDFdq4Wc.html For what you tell me it seems a problem of burned pixels in the DMD, but I also thought that my DMD is broken and I was wrong. luck.
@@fantasticofficecollection7742 I cleaned the socket and reseated the DMD chip a few times but had no luck. Perfect square dead pixels all over the screen =\. Will see if I can get a replacement. Thanks for the video though, I followed along to make sure I didn't mess up on reassembly.
