DM 900 Tuner and scanning issue

[Naveenkhan]

To all friends and experts
I hv DM 900 from Germany dual tuner..
Two weeks ago i observed that Tuner B failed to respond/scan signal of any Satellite either directly or via Desisque..
Two days ago i observed that DM has no signal of 13e on TUNER A ( i let u know all, i got 6.5 feet base on 100.5 and 108e and 88e on side LNBs, and 8 feet visiton on 13e base and 38e on side LNBs) but 38e is OK.
I did many attempts to improve signals via Android App DM Satfinder but got Nothing only Paksat signals.
Yesterday,
I called the technician and got good signal of both 13e and 38s .
I checked with some China receiver via Desicq ( Waterproof 10 switches) all was OK.
Then i tried with DM now NO signal both on 13e and 38e ( installed on 8 feet as described before).
Then checked directly without desicq Signal was OK.
Then tried with china receiver again via desicq, Signal was again OK..
I tried with different Nos on desicq switch, again No signal..
Now i am unable so far to understand the problem and how to resolve it...
If it was desicq, then it has OK signal to China receiver..
If it is DM with problem, it shouldnt work directly..
So needed help...
Sorry for being so long and boring detail wise

Then checked directly without desicq Signal was OK.

you need to cross check by replacing another DiSEqC switch ...ho sukta hay switch nay malfunction kerna sharoo ker dia ho
no comparison with non-enigma box

Signal ok without DiSEqC, then no problem with Tuners, Please share your Tuner Config here if possible

I faced same issue few days ago with starsat 90000 extreme HD. When my C band lnb 38e was not responding &13e signal drops. I change diseqc but result was same. Then i changed wire connectors & switch divider of 38e lnb, which is connected with other china receiver. Now all things are ok. Please check same.

Thanks for all
I did replace the wires...and all resolved..
But strange to undestand...why that wires and Desicq responds to china Box

Because of Chinese technology

when I purchased DM 900 ...it used to work by applying a jigarh....tuner A peh signals sahih aatay thay lekin tuner B peh signals aatay he naheen thay .....since this box is fixed ,both tuners work 100% okay.
