Hi JB and everyone. Here we go with the latest puzzler. One of the Duos I have been playing with is now working. However, when switching it on and changing channel early, sometimes it will go into starting loop. It will restart once or twice and then work perfectly the the rest of the time while it's on. Any thoughts of this one please. I keep thinking caps again but I could be wrong? I have already changed many caps on main board and PSU. Thanks. Regards, Jules.
See / check if you experience it with both lnb inputs, or either one. Disable one to check the other. If it happens to both, I would examine the u202 or the surrounding parts. If it is one of them then I would research the u808 / u809 depending on which lnb side it is happening on.
Thanks JB. With you mentioning LNB area, there is something I noticed. The LNB connector on tuner B is sticking out further than the one for tuner A. It also keeps rotating when I try to tighten it, could this be something that could be causing it? Thanks again.
Could be, maybe it creates, or has a close to short to ground, or when sticking a connector into it, or something in that way. Normally I replace them if they have been used for a long time, as this can give a better contact / reception when using a new one.
Thanks JB, I suppose it is a main board out job to remove the socket. Is a replacement socket hard to get hold of ?
Yes, you need to remove the mainboard to replace the lnb connector. Hard to find, no not really, just search with google, or on aliexpress etc to something like this.. SMA Female Thru Hole plug Right Angle 90 DEGREE And choose the one with the right mm size.
