LNB: Strange problem!!

[TheHighLander]

Hi,mates
I have got old Fuji lnb.It has recently got a problem..Most of frequencies must be reduced to get signal.
For example: to receive the signal of 11096,I must reduce about 15 digits to get signal, like this: 11081..This causes headache for me,,Any solution?
thx

I am experiencing a lot of problems with Cband LNB, it's shooting up and down. If I got like 70% in my strong receiver the signals usually drop to 45-50% and that cause the picture freez or skip.
Please can you help me solve it?

Why don't you simply change the LNB so as to make sure it's coming from the Lnb. One thing for sure if the problem is from the LNB there is not much you can do except to change it.

Try lowering your LO frequency offset by 15 MHz. 11050 rather than 11065 on your receiver.

reset your device and check after that

or try to use other lnb and tell us results

After some tests, I am sure that the problem comes of the LNB. I discovered also that the problems happen only to frequencies from 11700 to 12750 ranges.
This is a very rare lnb I hope a solution will be available.

If it's a standard DRO LNB, there should be 2 local oscillators (round, white plastic objects on the PCB a few mm thick) in the LNB with screw tensioners for fine tuning on them, the smaller one [for high band] sounds like it has loosened a little, you would have to open the lnb up to get at it & tighten it with meter readings on a meter,

I would say just change the LO frequency in your lnb settings to allow for the outage- keep the low band lo setting to 9.750 & just alter the highband from 10600 by the amount it is out (-15) & don't use the normal Universal defaults.

After few months, the difference increased from 15 to 66.
So, I increased the amount 10600 to 10666 in CrazyScan, EBSPro and DVB Dream..And I succeeded to have the signals of the right transporders.:thum:

But the question which plays in my mind:Will this alter will affect badly on the efficiency of my TBS Card? or this works only with CrazyScan, EBSPro and DVB Dream???

Might cause a problem at the top end on some tuners or software, seems to have altered quite a bit so if it's really important, you can consider opening it up & adjusting the tensioner on the high band Local Oscillator- try to use a small plastic screwdriver and have some outdoor sealant handy - put some on the LO tensioner after it's right to stop it moving again & you might need it on the case if it was sealed with it & doesn't have a rubber seal.
