    I can not guarantee if a new cpu solves it, but it could be.
    However, to buy somewhere this cpu may not so easy as it sounds, as also removing, replacing a cpu is not so easy without good equipment and tools.

    Hello, I'm from the Czech Republic and I'm quite unhappy and dissatisfied with the operation of the DM900, which are very defective, in one model the HDMI went out, in the other the LAN ethernet mesh and in both cases a complete replacement/replacement /CPU will be necessary, unfortunately I don't know which type I have with these models exactly, maybe BCM 7328 or BCM 7325, but I can't find them anywhere in the offers on google, I find out here that the replacement is possible, although quite demanding and only with the use of special soldering tools.

    Can you please tell me where and if this processor can be found somewhere and if so, whether you have a cartridge for it. Another option is to buy a complete main board from the Saudis for approx. 180 Euros, which seems a little too much to me, what kind do you have in this regard please your personal experience?

    Thank you for your response and please send me an e-mail:

    Thank you very much

    Hello Josef W.

    Sorry, I can't help you with your question, simply because I haven't dug into it.

    With the older dream and vu+ boxes I sometimes took the trouble to replace the cpu until I lost a lot of money on fake CPUs.
    After that I didn't feel like replacing it with new CPUs. but only when they were used old re-balled cpus.

    As for the processor, from what I see, it will be difficult to find a seller. re-balling the old one is often the best solution to try to repair.
    Using a stencil and using low heat solder paste instead of solder balls worked better in the past when I did it.
    But it's still a lot of work, and the risk of failure is always possible.

    If the question is related to the IRLML5203, than it's easy to find by example aliexpress.

    it's the Q2102 with marking code H5XG2, but the marking code could be different, but its the same.
